Abstract

A transport system for transport of a harvesting header comprises separate front and rear carriers in a configuration that permits a single person to prepare a harvesting header for transport. The wheeled front carrier engages a support member attached to one end of the harvesting header and includes a towing member and means of connecting the front carrier to a towing vehicle. A wheeled rear carrier comprises deployable straps that can be attached to the harvesting header. A winch applies tension to the straps and on retraction pulls the rear carrier up and into position underneath the header. The harvesting header is then lowered to transfer the weight to the carriers and the header then disconnected from the combine, and is ready for transport.

Description

HARVESTING HEADER TRANSPORT SYSTEM AND METHOD
Honey This invention is in the field of mechanical devices for transporting farm equipment. In particular, the invention relates to devices that are useful in transporting a harvesting header assembly.
Background:
For the last century, the general trend in agriculture has been the consolidation of farmland into larger and larger farming operations. In 1900 the average farm size in the U.S. was about 140 acres, which today the average size is over 400. Because of the way in which farmlands were originally surveyed and parceled, and the way in which land is acquired, large farms generally do not consist of contiguous plots of land. As a result, in order to manage a farm, farm equipment frequently must be moved from one site to another using public roadways.
For some self-propelled equipment this presents little problem. However, other types of farm equipment, for example combines, cannot simply be driven down the road as the header portion is generally too wide to be accommodate by public roadways.
Headers can

2 be as much as 40 feet in width (about 12 m). The standard lane width in North America is about 12 feet (3.7 m). Thus, transporting a harvesting header while installed on the combine can be virtually impossible, as it would completely tie up traffic in both directions on most single lane roads, the routes typically available from field to field.
As a result, the header on a combine generally has to be removed from the combine, loaded onto a trailer lengthwise so that it can be safely transported to the next field where combining operations are to take place. A variety of prior art solutions have generally taken the obvious approach of removing the header and placing lengthwise on a trailer, the header and trailer being narrow enough to fit safely within a single lane of a roadway.
For example, U.S. Patent No. 5,333,904 (Kuhns) discloses a trailer with supporting brackets onto which a harvesting header can be loaded and secured. The header is placed such that it is aligned longitudinally with the trailer, thereby allowing the header to be safely transported on public roadways. The fact that the header is placed onto the trailer means that this system cannot conveniently be manipulated by a single operator. Further, the use of brackets as support members means that the system is not readily adaptable to a variety of harvesting header configurations.
Later approaches to the problem include those such as are disclosed in U.S.
Patent No.
6,047,989 (Wood). That invention includes adjustable header support units that are configured to be more readily adapted to various header units. The solution, however, simply adds a plurality of mounting points for the supporting brackets, such that the user

3 can select a particular bracket mount point to more or less align with the desired engagement point on the header. Given its size, the system is still not particularly amenable to use by a single operator, and stills retains defined attachment points, which may or may not perfectly align with sites on the header to which one might wish to secure the header to the trailer.
Others have provided trailers that allow the header to be rotated around the longitudinal axis in order to save space and make it easier to effect repairs. For example, U.S. Patent No. 6,428,047 (Ka.derabek) discloses a trailer that allows the header to be placed on the trailer and then pivotally rotated in order to either provide access to the underside of the header, or to save space for storage of the header in the off-season. A
variation of this same theme is disclosed in U.S. Patent Publication No. 2009/0189382 (Nubel et al.). Still others have disclosed a trailer with a steerable wheel system on which headers can be transported, as is disclosed in U.S. Patent Publication No. 2010/0052289 (Frey et al.).
These prior art devices all suffer from similar limitations. For example, by using a fixed size trailer, a system may not be easily adapted for headers of difference sizes. More importantly, each of these prior art system are effectively a large trailer that is difficult for a single operator to manipulate. Generally, using prior art equipment requires two or three people in order to situate the trailer and move the header from the combine to the trailer.
Thus what is needed is a harvesting header transport system and accompanying method of use that simplifies the movement of a harvesting header from one site to another, and is

4 compatible with typically public roadways that are used to transport farm equipment from site to site. In addition, what is further needed is a system and method that can be used by a single worker.

Detailed Description of the Invention:
Prior art transport systems for harvesting headers have several limitations.
In some instances the systems require several people in order to position and load the header onto to trailer or other transport means. Still other systems are not readily adaptable to headers of different sizes. The present invention solves a number of these issues and provides a substantially universally adaptable transport system for harvesting headers and other difficult to transport farm equipment. Significantly, a single user can effectively employ the present invention.
In the present invention, the term "end" as it relates to the harvesting header is taken to refer to any position between the center of balance of and the physical end of the header.
The term therefore should not be taken to strictly mean the absolute end of the harvesting header. As a result, when referring below to placement of the front and rear carriers with respect to an "end" of the harvesting header, what is meant is that the front carrier can be positioned at some location away from the center of balance toward, and including a physical end of the harvesting header, and the rear carrier will be positioned at some

12 location on the other side of the center of balance and toward or at the opposite physical end of the harvesting header.
The invention comprises in some embodiments a front carrier 100 and rear carrier 200 that are configured to accept a harvesting header 300 for transport, as depicted in Figs. 1A and 1B. As shown, the harvesting header is supported by the front and rear carriers in such a way that the header can be transported lengthwise along a standard roadway.
Referring to the remaining figures, additional detail regarding the construction and operation of the invention will become apparent.
Fig. 2A depicts an embodiment of the front carrier of the invention. In one aspect of the present invention, the front carrier comprises a towing member 110 a front carrier wheel assembly 120 and a hitching means 112 that permits the towing member to be connected to a vehicle used for transporting a harvesting header. The front carrier wheel assembly comprises wheels 121 connected to each other by an axle 122. In a preferred embodiment, the front carrier wheel assembly comprises two wheels, although additional wheels can be include in the assembly if desired to more effectively support or distribute the weight of the harvesting header supported by the front carrier. Wheels suitable for use with the invention will be obvious to those of skill in the art, and generally typical pneumatic tires .. can be used. In addition, the front wheel assembly is configured such that the front wheel assembly portion can be steerable, those simplifying towing and maneuvering of the combine header once it is secured to the support system as described by the present invention.

13 The wheels and axle assembly are connected to the towing member via an axle mount 124.
In some embodiments the axle mount may be attached directly to the towing member. In other embodiments, as shown in Fig. 2A, the axle mount can be attached to a towing member receiver 116 by a portion of the header support mount 123. In other embodiments, the axle can be attached directly to the towing member receiver. The towing member receiver can be configured to be reversibly attachable to the towing member.
Providing a separate towing member receiver component permits the towing member to be removed from the wheel assembly, such as might be desired for storage thus minimizing the space required to store the various components of the present invention.
Where a towing member receiver is provided it can be secured to the towing member by a fastener 126. Suitable fasteners can include nut and bolt combinations, locking pins, and other like components.
The front carrier also comprises a structure designed to support one end of a harvesting header. In the embodiment illustrated in Figs. 2A and 2B, the carrier includes a header support mount 123. The header support mount is connected to the towing member, in some cases, by attaching to the towing member receiver. For improved strength and rigidity, the header support mount can also be attached to the axle mount 124. The header support mount further includes a front connector 125 that is designed to receive an end of a header support member 127. In some embodiments, the front connector can be a typical ball hitch.
One end of the header support member is designed to be attachable to a portion of the

14 harvesting header, typically a part of the header frame superstructure, via a front header attachment 129. The front carrier and associated support structures are generally designed to be attached to the bottom plane of the header, at or near the front end of the header, although in some embodiments it may be desirable to support the front end of the header by other means.
In some cases the front header support can comprise a plurality of members that are adapted to be telescoped within one another. In addition a telescoping front header support can further include locking means to restrict the movement of the telescoping members once the header support has been extended or retracted to a desired length. The front and/or rear carrier assemblies as described herein may further include shock absorbing means in order to isolate the combine header from vibration experienced during transport.
The front header attachment can comprise any kind of removable means of securing components, including nut and bolt combinations, locking pins, or a post onto which an end of the header support member can be inserted. Where a post is used, it may also include a locking pin or like arrangement to prevent the header support member from sliding off the pinion during transport. Where a post is used, the components can be designed such that the header support member inserts into an appropriately sized hollow post, or vice versa.
The opposite end of the header support member is designed to engage the front connector.
In some embodiments, the end of the header support member that engages the front connector can simply be a tube with an inside opening large enough to accept the connector, for example a ball hitch of a known diameter. In addition, and as shown in Figs. 2B and 2C, the header support member can comprise a upper member 1230 that attaches to the harvesting header, and which slidably engages a lower member 1232 which includes the portion that engages the front connector.
In use, this allows the header support member to be attached to the harvesting header, and then the lower portion extended into position to engage the front connecter.
Then, when the harvesting header is ready to be lower, the upper and lower member simply slide relative to each other to effectively shorten the length of the header support member. The lower member can further include a flange 1234 that provides a stop that prevents further shortening of the header support member past a certain pre-determined length.
Figs. 2B
and 2C depict the header support member in the retracted and extended configurations, respectively. As can be easily appreciated with reference to Fig. 2C, as the combined header is lowered, the upper member will slide over the lower member until the upper member reaches the flange, at which no further shortening will occur, and a portion of the weight of the harvesting header will be supported by the front carrier.
For improved security when transporting the harvesting header, a safety 126 can be included to insure that the header support member does not inadvertently disengage from = the header support member mount during transport. Such safety devices include chains, locking pins, or nut and bolt arrangements well known in the art.

The invention further comprises a rear carrier 200 that in cooperation with the front carrier is designed to support a harvesting header during transport and/or storage. In a preferred embodiment, depicted in Fig. 3A, the rear carrier comprises a frame 210 that serves as a support for components adapted to receive the harvesting header, and at least one rear wheel assembly 220 that is attached to the rear carrier. Attachment of the rear carrier frame is preferably to the bottom plane of the header within a region termed the rear carrier support zone.
Analogous to the front carrier, the wheel assembly comprises wheels 221 connected by an axle 222. In a preferred embodiment, the rear carrier wheel assembly comprises two wheels, however, as discussed above for the front carrier, more than two wheels may be desired in order to support heavier loads or to distribute the load being carried. For example, in some embodiments it is conceivable that the present invention could be designed to carry more than one harvesting header, with a second header "stacked" onto the first. In these cases, a more robust wheel assembly on both the front and rear carrier assemblies might be required. The wheels on the rear wheel assembly will preferably already be oriented in the desired direction of transport when the rear carrier frame is attached to the rear carrier.
The rear carrier further includes a first support member 212 and second support member 213 connected to the frame, and which are configured to cooperate to support an end of the harvesting header, opposite to that supported by the front carrier. The support members are situated generally perpendicular to the longitudinal axis of the rear carrier, although other configurations and placements than those shown in Fig. 3B can be employed without departing from the scope of the invention. The number and location of support members will be obvious to those of skill in the art.
The rear carrier further comprises a winch and an extendable header strap system designed to engage and secure the harvesting header to the rear carrier. As shown in the accompanying Figs. 3A-3C, in one embodiment a winch 230 is situated on one side of the frame. The winch can be manually operated, in which case it will include a handle 231 to allow a user to operate the winch mechanism. The winch can also include typical features such as a lock, which locks the winch in a position, and a release in order to disengage the lock. In some embodiments it may be desirable to provide a motorized winch rather than one that is operated manually. In such cases, the winch will include some form of power supply, for example, a battery as in the case of an electric motor, or some means of connecting the motor to an external power supply.
The drive mechanism of the winch is connected to a winch axle 235, which passes through and is supported by members of the frame. The winch axle engages the proximal end of one or more straps 241, 242, the straps designed to reversibly connect the harvesting header to the rear carrier. As can be appreciated, the winch can be operated to permit the extension or retraction of the header straps depending on whether the user is securing or removing the rear carrier from the header.

In the depicted embodiment, four straps are provided, two front straps 241 and two rear straps 242. In the depicted embodiment shown in Figs. 3A-3C, the straps extend from the winch axle and are fed through guides provided in the frame. As shown, the two front straps can be configured to pass through respective front strap guides 243, while the two rear straps can be configured to be fed through corresponding rear strap guides 244. The distal ends of each strap can then be pulled upwards where they can engage a location on the harvesting header via strap fasteners 245 located substantially at the end of each strap.
In some embodiments, the strap guides may simply provide a smooth surface for straps to glide over. The strap guide will also be operative to bear a portion of the tension applied to the header straps when the winch mechanism is operated. In some other embodiments, it may be desirable to provide a roller mechanism over which the strap runs, the roller mechanism substantially reducing friction between the strap and its guide, and thereby reducing wear and tear on straps.
Generally, the header straps will further comprise means to allow them to be reversibly secured to the header structure. In some cases the means to reversibly secure the headers to the header will comprise at least one of a hook, and a snap, or other analogous structures.
Strap fasteners can comprise any of a number of structures, including open hooks that engage a portion of the harvesting header superstructure. The precise nature of the means of fastening a strap to the harvesting header is not considered limiting to the scope of the invention located at the distal end of each strap.

For example, the distal end of the strap may include a hook or eye designed to engage a complimentary structure located some distance away from the distal end of the strap. In this configuration one will appreciate that to secure the strap to the header, the end of the strap can be passed through some portion of the header structure and then looped back on itself to secure the end back to the strap. In some embodiments, the header strap hook might engage a complementary structure on the header without requiring any portion of the strap to directly engage or otherwise wrap around a portion of the header structure.
The rear carrier also includes a stand 260 attached to the frame. In some embodiments the stand is designed to be movable. Thus, when the rear carrier is being positioned, or when being stored, the stand maintains the rear carrier substantially level to the surface it is sitting on. This improves the ease of use of the rear carrier in terms of positioning it with respect to the harvesting header. It also keeps components of the frame off the ground thereby preventing inadvertent damage to the front of the rear carrier frame structure.
Conveniently, the stand can be pivotally mounted such that when not in used it can be rotated and secured out of the way. The stand can further include means of securing it in a desired position, such as through the use of a locking pin to engage the stand member with respect to a mount that connects the stand to the frame. In essence, the operation of the stand is analogous to that of a kickstand and so those of skill will readily appreciate how the stand operates and the various configurations that are useable in conjunction with the present invention.

The apparatus of the present invention as described herein provides additional advantages in a method of securing and transporting a harvesting header that improves significantly upon prior art solutions to this problem. A fundamental limitation in prior art apparatus is the need to have multiple people involved in the traileting of the harvesting header. This is obviated by the present invention.
In one aspect, the front carrier will be positioned between the center of balance and one end of the harvesting header to be transported, under the bottom plane of the header. The relatively small size of the front carrier makes it easily amenable to moving by one person.
Once in the desired position, a user can then attach the front carrier to the header via the header support member 127. As discussed above, one end of the header support member engages a header support member mount 123 on the frame of the front carrier, while the opposite end engages a portion of the harvesting header superstructure. The header support member is designed to be able to pivot about the front connector.
As discussed in some embodiments the front connector comprises a ball hitch and the header support member is designed to be able to engage and pivotally rotate laterally about the hitch such that the front carrier can more accurately track the vehicle towing the harvesting header. The end of the header support member that engages the harvesting header can be attached in any number of ways including clamping to the superstructure, bolting to holes in the harvesting header framing that are designed to accept the header support member, and other similar attachments.

In some cases it may be desirable to design the system such that the mounting point on the harvesting header is pivotally attached to the header support allowing that end of the member to rotate laterally. In either case, in preferred embodiments at least one end of the header support member will be pivotally connected to its respective mounting point in order to permit the lateral rotation of the front carrier relative to the longitudinal axis of the harvesting header during positioning of the front carrier and/or towing of the header.
The rear carrier provides a completely novel method of connecting a transport system to a harvesting header. In prior art transport systems, the harvesting header is lowered onto a trailer, secured, and then disengaged from the rest of the combine vehicle. In the present case, the inventors have developed the concept of connecting the rear carrier to the combine and then raising the rear carrier into position, and finally securing the harvesting header so that it is ready for transport.
Therefore, in accordance with an embodiment of a method of transporting a harvesting header, the rear carrier is first positioned at a point under the bottom plane of the harvesting header between the center of balance towards an end of the harvesting header opposite to that where the user intends to (or already has) positioned the front carrier.
At this stage the harvesting header is attached to the combine and positioned in an elevated position so that the user can easily place the rear carrier under the header.
Releasing the locking mechanism on the winch, the user is able to fully unwind and/or extend the straps from the winch axle and if there are not already so positioned, to pass each strap through its appropriate strap guide in cases where the apparatus includes one or more strap guides. Each strap will then be attached to a location on the harvesting header as described above, and as depicted in Fig. 3B. Once each strap is in place, the user will operate the winch to roll the straps back onto the winch axle, thus retracting the straps.
.. Operating the winch can be performed manually using a winch handle as depicted in the accompanying drawings, or via activation of a motorized winch in embodiment employing that type of a winch drive mechanisms.
Winding the straps onto the axle will eventually take the slack out of the straps and when sufficient tensions is created, the rear carrier will be lifted off the ground and upwards towards the harvesting header where it will eventually be secured the rear carrier support zone. The strap guides operate to transmit the tension applied on the straps into an upwardly acting bias force sufficient to lift the rear carrier into position, as shown in Fig.
3C.
The winch will be operated until the user determines that the rear carrier is positioned securely under the harvesting header and in the desired position within the rear carrier support zone. Once that is achieved the winch can be placed in the locked position in order to maintain the tension on the straps. Once satisfied the rear and front carriers are properly .. secured (as can appreciated by reference to Figs. 2C and 3C, the user can then lower the harvesting header towards the ground such that the wheels of the rear carrier are now on the ground supporting a portion of the weight of the header, with the remainder of the load being supported by the front carrier, as shown in Fig. 1A. In addition to being able to conveniently transport a combine header as shown in Fig. 1A, the invention can be adapted to secure and transport other bulky loads 301 as shown in Fig. 1B.
In some embodiments of the method, the user can position and install the rear carrier support as described above, and then once the rear carrier support is in position, then connect the front header support, and then lower the header to align and attach the front carrier to the front carrier support. It will be apparent to those of skill in the art that the precise order in which the front and rear carrier supports are secured to the header are not limiting to the scope and practice of the invention. In some cases, a user may decide to first secure the front carrier support and then the rear, or vice versa_ In either case, once the front and rear carrier supports have been secured to the header and the header lowered such that the entire weight of the header is borne by the front and rear carriers acting cooperatively, the header can then be safely disconnected from the combine.
Depending on the preferences of the user, in some cases it may be desired to secure the rear carrier in place, then attach the header support member at a location towards the other end of the carrier, and then secure the front carrier to the header support member prior to lowering the harvesting header. In other cases, it might be desired to secure the rear carrier in position, then lower the harvesting header part way to the ground, and then position the front carrier under the header support member, and then lower the header the remaining distance to engage the header support member to the front connector mount on the front carrier. As can be seen the specific steps can be performed in various orders and achieve the same result of securing the harvesting header to the front and rear carriers of the present invention. The preferred order of executing these steps will be one of personal preference of the user.
Finally, once the front and rear carriers are positioned and secured, and the harvesting header is lowered such that the weight of the header is supported on the carrier system, the header can then be disconnected from the combine. At this stage the harvesting header is ready for transport and can simply be towed away after connecting the front carrier to a hitch or other like connecting on the vehicle to be used to tow the header.
Upon moving the header to the desired site, the steps by which the header was secured to the front and rear carrier are simply reversed. In some cases, the harvesting header may be left mounted on the carrier system as may be desired for storage after the growing season is over.
Thus, it is clear that the described embodiments provide an improved device and method of transporting a harvesting header. In addition, it will be apparent to those of skill in the .. art that by routine modification the present invention can be optimized for use in a wide range of conditions and applications, and with various models of farm equipment. It will also be obvious to those of skill in the art that there are various ways and designs with which to produce the apparatus and methods of the present invention. The illustrated embodiments are therefore not intended to limit the scope of the invention, but to provide examples of the apparatus and method to enable those of skill in the art to appreciate the inventive concept.

Those skilled in the art will recognize that many more modifications besides those already described are possible without departing from the inventive concepts herein.
The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims.
Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms "comprises" and "comprising" should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that arc not expressly referenced.
