Abstract
A rotary mower discharge chute capable of allowing material to be ejected within a swath extending between transverse and fore-and-aft lines is provided. The chute is open along its fore-and-aft outer dimension as well as its transverse dimension to permit discharge of cut material through either or both openings or through the rear opening when the transverse opening is blocked by tall grass or border obstructions.
Description
2~ ~6821 MOWER DIS~ CHUTE
Back~round of the Invention 1. Field of the I~lvention The present invention relates to implements used in cutting grass and other ground vegetation and more particularly to a discharge chute used with rotary mower implements.
2. Description of the Related Art Rotary mowers and particularly multiple spindle rotary mowers are used to cut grasses, weeds and similar vegetation in a variety of conditions. Not infrequently, they are used to cut vegetation which is substantially higher than the height of the housing of the mower implement. Typically, the discharge chutes on the type of mowers used for this purpose open to the side.
When cutting tall vegetation, the opening of these chutes can be blocked by the tall, uncut vegetation, preventing ejection of the cut material. As a result, the chute becomes clogged and the operator must shut down the mower to clean it.
A similar problem can arise when these implements are close to fences or walls, since the opening of the discharge chute can also be blocked by these obstructions.
One approach used to minimize clogging of side discharge chutes when mowing along obstructions has been to angle the chute so that it discharges material rearwardly as well as sidewardly. While this can sometimes prove acceptable with single blade implements, it often presents problems with multiple blade units since they are much larger. With such units, a strong air flow is desirable to propel the greater volume of material cut by the multiple blades. This can best be achieved by transversely aligning the blades to provide a relatively straight air flow path from and along the blades to and through the discharge chute. To discharge the cut material rearwardly on multiple spindle units mounted beneath the tractor, and maintain aligned blades, the rotary mower housing has to be angled rearwardly. Since the fore-and-aft 2~66821 space between the front and rear tractor wheels is limited on many vehicles, this approach is not desirable.
Sl~mmary of the Invention It would therefore be desirable to have a chute that will discharge cut material transversely and will not clog when used with multiple blade rotary mower implements in tall vegetation, along fences and other borders. It would further be desirable to have a chute that can be used with a rotary mower having a high air flow speed that permits side discharge or bagging of the cut material. It would also be desirable to have a chute that does not require the implement to be angled rearwardly, so that the implement space required beneath, in front of or behind the vehicle in minimized. It would finally be desirable to provide a discharge chute that would discharge rearwardly when the transverse discharge is blocked, as can occur when mowing in tall grasses or close to walls, frames and fences.
Towards these goals, there is provided a discharge chute that is usable with a multiple blade rotary mower having transversely aligned blades that provide a high flow rate of cut material towards the chute. The chute further can be used without angling the implement or chute rearwardly, thereby requiring only a minimum of fore-and-aft mounting space in front of the tractor, between its wheels or behind it. The chute opens transversely as well as rearwardly to permit discharge through its fore-and-aft extending outer dimension or its transversely extending rear dimension. When transverse discharge is blocked, material is able to flow out beneath the rear surface of the chute as the tractor moves ahead.
The improved discharge chute includes a forward vertical wall which is essentially an extension of the mower's front housing wall. This forward wall extends transversely outwardly from the discharge opening of the implement housing.
The chute further includes a top surface composed of first and second portions. Both portions are generally horizontal and extend outwardly and transversely from the discharge opening 2 1 6682 t in the housing. The first portion extends rearwardly as well, sloping down to the sloping second portion which extends yet further transversely and rearwardly. The second portion terminates at first transversely extending and second fore-and-aft extending edges, both which are positioned above the plane of cut of the blades.
With the present discharge chute, material passing through the opening of the housing can travel along a line tangent to the front edge of the blade and be ejected transversely outwardly through the chute. Similarly, material can be ejected by the blade along a fore-and-aft extending tangent line to pass through the rear opening of the chute.
Material can also be ejected within the swath between these lines since the chute is open both along its side and its rear edges permitting material to be e~ected and discharged even when the transverse opening is blocked.

Description of the Preferred Embodiment Looking first to Fig. 1, there is illustrated in plan view a schematic depiction of a multi-spindle rotary mower implement 10 provided with three blades 12, 14, and 16. The implement frame or housing 18, which encloses the blades 12, 14, and 16, includes a front vertical wall 20, a rear vertical wall 22, side vertical walls 24 and 26 and an opening 28 at the right side through which material can be discharged transversely. The blades 12, 14 and 16 are transversely aligned and cooperate to provide a strong air flow for ejecting the cut material from each blade 12, 14 and 16, along the front of the housing 18 as depicted by the arrows, and out through the opening 28 and chute 30.
As best shown in Figs. 2, 3, and 4, the discharge chute 30 includes first, second and third surfaces 32, 34 and 36.
The first surface 32 takes the form of a forwardly wall which is attached to the front wall 20 of the housing 18. The forward wall 32 includes a first edge 38 which may be joined by bolts 40 or other fastening means with the vertical forward wall 20 of the mower housing 18 as well as a second edge 42 along its top side which is joined with the generally horizontal top surface 44. The generally horizontal top surface 44 is composed of the second and third chute surfaces 34 and 36 with the second surface 34 being joined by hinges or other fastening means along its first edge 46 with the mower housing 18, along its second edge 48 with the forward wall 32 and along its third edge 50 to the third surface 36 which slopes downwardly and outwardly. The second surface 34 is attached by bolts 52 or other fastening means to the mower housing 18 at its rear.
The third surface 36 is integral with and attached to the third edge 50 of the second surface 34 along the bend line or first edge 54 of the third surface 36. It slopes downwardly and outwardly away from the first edge 54 and extends to a fore-and-aft extending outer or second edge 56 as well as to a third or rearward edge 58 which extends generally transversely. The two edges 56 and 58 slope downwardly to join at a tip 60, and terminate at a vertical elevation that is spaced above the plane of operation 62 of the blade 16 (see Fig. 3) .
2 1 ~682f As illustrated in Fig. 4, the lower edge 64 of the chute's forward wall 32 extends from its attachment with the front wall 20 of the housing 18, upwardly to a terminal point 66 transversely spaced from the mower opening 28. The outer point 66 of this lower edge 64 terminates at a height roughly equivalent to the height of the tip 60 of the third surface 36, both being above the plane of operation 62 of the mower blades 12, 14 and 16.
Looking now to Fig. 5, there is depicted in schematic form the housing 18, the discharge chute 30 and the one blade 16 adjacent the opening 28 of the housing 18. The one blade 16 is provided with a center of rotation at 68 causing the end of the blade 16 to pass through the circular path defined by the dotted line 70. The discharge opening 28 of the housing 18 extends between the forward vertical wall 20 of the housing 18 and the rear vertical wall 26 of the housing at 18. This large opening 28 makes it possible for material to be ejected from and by the blade 16 in a wide swath 72 that extends through this opening and between the tangent lines 74 and 76.
In operation, the multiple blade rotary mower 10 illustrated in Fig. 1, would usually be carried by a tractor between its front and rear wheels. It could also be carried in front of or behind the tractor. As the mower 10 cuts, it also operates to generate an air flow within and along the forward edge of the housing 18 as depicted in Fig. 1 by the arrows at the forward edge of the housing 18. Each blade 12, 14 and 16 would rotate clockwise, preferably in a timed relationship to generate this air flow and to cut particles of grass or other vegetation, ejecting them into the air flow for discharge out the opening 28 of the housing 18.
As material is cut and propelled into this air flow, it would be propelled out the opening 28 of the housing 18 and through the discharge chute 30. Since the plane of operation 62 of the blades 12, 14 and 16 is below the lowermost portions of the discharge chute 30, material can be ejected beneath it and within the swath 72 defined by the tangent lines 74 and 76.
Looking again to Fig. 5, it is shown that cut material can be propelled by the blade 16 through the housing opening 28 forwardly and transversely along the tangent line 74.
Since the chute 30 is open at its transverse side, the material can clear the forward edge of the forward wall 32 at an angle of approximately 11 degrees above a transverse line and still exit the chute 30. Further, material can escape from the housing opening 28 and be ejected by the one blade 16 rearwardly along the fore-and-aft extending tangent line identified as 76. With the transverse and rearwardly opening chute 30 of the preferred embodiment, material can be ejected by the blade 16 and discharged through the chute 30 throughout the 101 degree swath 72. As is evident from Figs. 1, 3, and 4, the surfaces 34 and 36 slope downwardly and rearwardly, serving as a shield against upwardly ejected rocks and/or similar materials. Not only do these surfaces 34 and 36 deflect such materials, but their outer edges 56 and 58 extend relatively low to the ground, sufficiently spaced from the blade 16 so that they provide barriers to an operator's foot preventing it from projecting beneath them and into the blade path 70.
When operating in tall grasses or adjacent a fence or other border at its outer transverse edge, the chute 30 permits cut material blocked at the transverse outlet or edge 56 of the chute to fall beneath the chute 30 and be passed over by the rear edge 58 of the chute 30 as the tractor moves ahead. Accordingly, materials prevented from being ejected transversely would not clog the discharge chute 30 since it can be passed over by the open rearward surface 36 of the discharge chute 30.
In contrast some prior art chutes 78 such as that illustrated in Fig. 6 have a swath of discharge 80 much more limited than is provided in the present invention. As is also common, these chutes are often angled rearwardly to discharge material, but so not allow material that is blocked from transverse discharge to escape rearwardly from beneath the chute as the tractor moves ahead.

The first surface 32 takes the form of a forwardly wall which is attached to the front wall 20 of the housing 18. The forward wall 32 includes a first edge 38 which may be joined by bolts 40 or other fastening means with the vertical forward wall 20 of the mower housing 18 as well as a second edge 42 along its top side which is joined with the generally horizontal top surface 44.

The second surface 34 is attached by bolts 52 or other fastening means to the mower housing 18 at its rear.
The third surface 36 is integral with and attached to the third edge 50 of the second surface 34 along the bend line or first edge 54 of the third surface 36. It slopes downwardly and outwardly away from the first edge 54 and extends to a fore-and-aft extending outer or second edge 56 as well as to a third or rearward edge 58 which extends generally transversely. The two edges 56 and 58 slope downwardly to join at a tip 60, and terminate at a vertical elevation that is spaced above the plane of operation 62 of the blade 16 (see Fig. 3) .
2 1 ~682f As illustrated in Fig. 4, the lower edge 64 of the chute's forward wall 32 extends from its attachment with the front wall 20 of the housing 18, upwardly to a terminal point 66 transversely spaced from the mower opening 28. The outer point 66 of this lower edge 64 terminates at a height roughly equivalent to the height of the tip 60 of the third surface 36, both being above the plane of operation 62 of the mower blades 12, 14 and 16.
