Abstract
ABSTRACT OF THE DISCLOSURE
A self-propelled swather includes a front drive wheel at one end thereof and a rear drive wheel at the other end with a castoring support wheel on the rear side between the two drive wheels. The drive wheels are each driven by a variable speed hydraulic motor so that side draft or drag of one end is eliminated. Steering from a cab at one end of the swather is by hydrostatic means and the rear drive wheel assembly can be turned 90° for trans-port. When in the transport position, all of the power can be directed to the front drive wheel thus increasing the drive speed of the swather under these conditions.

7~ 6 which includes a transversely extending rame with a swather unit mounted thereon and which is pulled by a tractor, from one end of the swather~
The main disadvantaga to this type o swather is the fact that the outer end of the swather drags back sometimes as much as five feet which makes it difficult to manoeuver with the tractor and oten involves complica-ted structure in an attempt to eliminate the drag back or side draft o the outer end.
Also considerable strain is placed upon the struc-ture under these circumstances, particularly in relatively wide swathers which can exceed 24 eet.

~ 77~26 DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, reference character 10 illustrates a transverse main frame, reference character 11 a swather mit, and re-ference character 12 a cab situated upon the main frame.
The main frame consists of a transversely extending main beam 13 having a forwardly extending support means in the form of a beam 14, secured to and extending forwardly from one end 15 of the main beam 13 and substantially at right angles thereto.
The swather unit 11 is convantional in construction ;~
and may either be of a center delivery type as illustrated in Figure 1~ a right delivery type as illustrated in Figure
2 or a left delivery type as illustrated in Figure 3. How~
ever~ as this construction is conventional, it is not be-lieved necessary to discuss same further.
This swather unit 11 is mounted within the main r~me 10 by means of members 16 and 17 which extend from the main beam 130 Means may or may not be provided to ad-just the height of the swather unit within the main frame~
- but once again as this is conventional, it is not believed necessary to describe sam~, A front drive wheel assembly collectively designa-ted 18, is mounted adjacent the front end of the forwardly extending beam 14 by means of a vertical post 19 pivotally supported within the front end of the beam 14.
A wheel 20 i9 journalled for rotation upon the ,,~
lower end of this post 19 which extends at right angles from the vertical post 19 in the usual mannerO
,`;`
, ~
An hydraulic motor shGwn schematically by reference character 21, is operatively connected to the ~ront wheel 20 and is adapted to rotate same at varying speeds and .in either direction as will hereinafter be described~
A rear drive wheel assembly collectively designated 22, is mounted adjacent ths outer or distal end of the main beam 13 and it also consists of a vertical post 23 pivoted or journalled for rotation within tha main beam 13 and in-cludes a wheel 24 journalled for rotation upon ~he lower horizontal end of the member 23, once again in the usual manner~
A further hydraulic motor 21A is operatively con-nected to this rear wheel 24 to rotate same in either direction and at variabl2 speeds~
~777Z6 A castor wheel assembly collectively designated 25, is mounted to the main beaml3 in a loccation between the wheel assembly 18 and the wheel assembly 22, rrhis castoring wheel assembly 25 includes the support member 26 journalled for rotation within the ]main beam as indica-ted by reference character 27 and carries the castoring wheel 28 journalled for rotation upon the lower hori~on-tal end of the member 26 in the usual manner and th:is wheel is slightly behind the main beam 13 as clearly shown in the drawings.
These three wheel assemblies 18, 22 and 25 give a three-point support for the swather as clearly shown, ' ' A cab unit collectively designated 29 is mounted upon the main frame adjacent the junction of the main beam 13 andthe orwardly extending beam 14 and Figure 4 shows a bracket assembly 30 extending outwardly from this junction point so that the cab unit 29 can be mounted within the bracket 30 by means of a pivot pin 31.
This means that the cab can be movad from a straight-ahead swathing position shown in Figures 1 and 2, to a trans-port position shown in Figure 3 which is substc~ntially at 90 from the swathing position shown in Figures 1 and 20 -- 8 ~
777;~6 It will also be noted that this cab unit is situa ted above the main frame 10 so that an adequate view is obtained by the operator, not only of the crop being swath but of any obstructions which may interfere.
Situated within this cab ~not illustrated) is a :
steering wheel shown schematically by reference character 32 in Figure 6, and a valve control indicated by reference character 33 in Figure 6.
' :
The valve control controls the fluid from a pump 34 fed by a reservoir 35. Conventional conduits shown schematically in Figure 6, extend between the valve con-trol and the hydraulic motors 21 and 21A thus enabling the operator to select firstly the ~orward or reversa rotation of wheels 20 and 24 and sacondly, the relative speeds thereof so that if, for example, the swather is in the straight-ahead swathing position, the speeds of wheels 20 and 24 may be adjusted readily so that there is no drag back or side draft of the outer end of the .
swather assembly~ :
~.' ' The pump also supplies fluid to the steering motor 35A shown schematically in the drawings and taking the form of a hydrostatic motor operatively connected to the vertical spindle 19 to supply steering to the :~ront ..... - .
., ........................ ' .
.:
wheel assembly 18.
; A valve (not illustrated) may be connected to the hydrostatic motor 35A and to the steering wheel 32 so that steering is readily effected. However, such structure is well known so that it is not believed necessary to show details ` thereof.
`:
When it is desired to corner the swather, the front wheel 20 is steered as necessary so that, for example, the front wheel takes up the position shown in Figure 2. The cas-tor wheel assembly 25 also automatically tracks as illustratedin Figure 2 with the rear wheel assembly not turning under these conditions. However, if a sharp turn is necessary, the speed of the rear wheel 24 may be decreased or even reversed .: .
and the speed of the front wheel 20 may be increased.
It will therefore be seen that the swather is ex-tremely manoeuverable under all conditions.
When it is desired to transport the swather, it is moved to the transport position shown in Figure 3.
Under these circumstances, the rear drive wheel assembly .
~. .
$~
:.
~77~6 22 is moved through approximately 90 so that it is sub-stantially parallel with the main beam 13 and in this con~
naction, a fluid operator 36 is provided extending hatween the main beam 13 and an offstandLng member 37 secured to the rear wheel assembly 22, When in the position shown in Figurs 2, the wheel is fixed in the straight-ahead posi-tion but when the fluid operator is extended as shown in Figure 3, the wheel swings through approximately 90 as shownO A positive lock (not illustrated) may be provided for these two positions which may take the form of a pin engaging within apertures in the wheel assembly and the main beamc When in the transport position, the front wheel as-sembly is turned by the steering wheel to the position shown in Figure 3 and of course the castoring wheel auto-matically tracks as shownO
The cab may also be moved through approximately 90 to take up the position shown in Figure 3 and the cab may be locked in either position by means of a pin assembly shown schematically in Figure 5 and identified by reference character 38.
This enables the operator to have good vision for transport of the swather, particularly along public 1~77~6 roads and the like.
When in the transport position, the valve control 33 is preferably provided with means whereby all of the power may be directed to the front wheel assembly hydraulic motor 21 from the rear wheel assembly hydraulic motor 21A. This gives approximately twice the power to the front wheel and enables the swather to be driven in transport position, at a speed greater than when in the straightahead swathing position.
DRAWINGS SUPPORTED BY THE SUPPLEMENTARY DISCLOSURE
Figure 7 shows the rear drive wheel portion of Figure 1 in the steering position for a right hand turn.
Figure 8 is a schematic plan view of the steering mechanism and draft control.
Figure 9 is a ~op plan view of the swather showing the swather section in tandem.
In the embodiment illustrated in Figures 7, 8 and 9, the front steering and drive wheel assembly 18 is mounted upon a relatively short frame section 14A which in turn is pivoted to the front of the forwardly extending frame member 14, by means of vertically situated pivot pin 39 and a fluid operator collectively designated 40 extends between a lug 41 adjacent the rear end of the portion 14~ and an offstanding arm 42 connected to the steering post 19. The fluid operator 40 is connected to the steering wheel in such a manner that rotation of the steer-ing wheel operates an hydraulic valve (not illustrated) which . ~
~..,,~
~3777Z6 controls hydraulic fluid under pressure to the fluid operator 40 thus turning the front wheel in synchronization with the steering wheel.
Figure 8 shows a draft control system in which con-; 5 trol valve 33 is provided with two sections, one operatively connected to the front left drive wheel for variable oil flow control and the other conneted to the rear right wheel for var-iable oil control.
This valve is in the form of a shuttle valve assembly operated by a pair of rods 43 and 44 running substantially parallel with the main frame member 13 and being connected to an actuating plate assembly collectively designated 45 which in turn is pivoted centrally as at 46, to a main control link 47 which in turn is pivoted by one end thereof to the frame member 13 as indicated by reference character 48.
The basic position of this link 47 is controlled by an operating lever 50 within the cab pivoted horizontally adja-cent the lower end thereof as at 51 and connected to lever 47 by means of rod 52~ This rod 52 which includes a spring loaded mounting assembly 53, is connected to the distal end of the link or lever 47 as clearly shown in Figure 8.
The control lever 50 is capable of being set in any one OL three positions. Neutral as shown in Figure 8 under which circumstances the shuttle valves 33 are inoperative, forward in which instance the lever 50 is moved in direction of arrow 52, , ~ ~
7~Z6 and reverse in which the lever 50 is moved in the direction of arrow 53.
The rods 43 and 44 are pivoted to the member 45 one upon each side of the pivot 46, by means of pivots 54 and 55 and an extension 56 extends centrally of the pivots 54 and 55 ;
and in substantial alignment with pivot 46. A link 57 is pivo~
tally connected by one end thereof to portion 56 of pivot 58 ~:
and extends forwardly to be connected to a crank arm 59 by means of pivot 60, the crank arm being pivoted to adjacent the front end of the forward extension 14 of the frame as indicated by reference character 61.
A transport and field position cylinder assembly col-lectively designated 62 is mounted by one end thereof to lugs 63 towards the front end of member 14A with the piston rod 64 being pivotally connected to the other end of the crank link 59 as in-dicated by reference character 65 and this piston and cylinder assembly 62 normally acts as a fixed or rigid link when the swather is in the field position. When the control lever is in the forward or reversed position, and the swather is in the field :
position, the rods 43 and 44 route oil from the pump 34 to the hydraulic motors 21 and 21A thus supplying drive to the swather through the wheel assemblies 18 and 22.
Under these circumstances the draft control system is in the position shown in Figure 8 with the portion 14A being in alignment with the frame member 14.
`~,~"
~ .
, ~7~726 ' However when -the steering wheel is turned to the leEt : or right, the piston and cylinder assembly 40 turns the front wheel 18 around the vertical pivot 19. This applies a draft ~ force to the portion 14A and pivots it slightly around its pivot :~ 5 39 in one direction or the other depending upon the direction of wheel 20, and as indicated by double headed arrow 66. This moves the piston and cylinder assembly 62, which is acting as a rigid link, thus actuating crank link 59 and pivoting lever 45 around its pivot 46 thus moving rod 43 in one direction and rod 44 in the other direction which in turn actuates the shuttle valves 33. As an example iE the swather is turned to the right, then the linkage causes the hydraulic motor 21 to speed up and the hydraulic motor 21A to slow down. If the swather is steer- :
~ ed to the left, then the rods 43 and 44 are reversed thus caus-~ 15 ing the hydraulic motor 21 to slow down and the hydraulic motor ; 21A to speed up thus facilitating the turning of the swather.
. ~ .
If a servere right turn is made then the lever 45 moves suffici.ently to actually reverse the direction of hydraulic motor 21A thus facilitating a right hand turn by backing up the right hand end of the swather.
When the swather is moved to the transport position, piston and cylinder assembly 62 is retracted so that portion 14A
extends at right angles to portion 14 under which circumstances ; an offstanding lug 67 adjacent pivot 65, engages frame member 14 and prevents the draft control from operating as of course there :~ is no necessity to utilize same.
~ 77~6 Figure 9 shows the swather with a right hand exten-sion swather section llA pivoted to one end of the swather sec-tion 11 around pivots 68 which permit the two sections to ar-ticulate in a vertical plane,.
A support wheel assembly 69 is pivotally secured to the frame 14B of the section llA adjacent the distal end thereof and this wheel is steerable by means of link 70 extending between arm 37 o wheel assembly 22 and a similar arm 37A of wheel as-sembly 69 so that the steering of the wheel assemhly 18 when in the field operating position shown in Figure 9, also steers not only wheel assembly 22 but also wheel assembly 69.
This wheel assembly 69 can also be moved to the trans-port position similar to wheel assembly 22.
Due to the width of the -tandem swather assembly illus-trated in Figure 9, a further castor wheel assembly 25A may beprovided adjacent the inner end of the frame 13. Also in this particular structure, the cab 12 is mounted inboard of the or-wardly extending beam 14 with the engine assembly 71 being mount-ed upon the frame between the cab and the forwardly extending member 14.
In conclusion, there are two basic positions which the two drive wheels 20 and 24 of the swather can assume. One is a longitudinal position which is for transport. In this position, the ront wheel functions as the steering wheel and the rear wheel is fixed in the longitudinal position and trails therebe-.
~1771~726 hind.
The other position is the field operating position illustrated in Figure 8. In this position, the front left wheel 20 serves as the main steering wheel~ The sharper the turn, the more the draft control mechanism is activated. In order to make a sharp right turn, the draft control mechanism is designed to reverse the rotation of the right rear wheel 24 and turn that wheel approximately 40 to the right as illustrated in Figure 7, thus drawing the right end of the table back while, at the same time, moving the whole table to the left. These movements im-prove the position of the swather for forward movement after the turn. Essentially the same basic procedures apply to the a sharp left turn as well as right turns. The sharp right turn movement is shown in phantom in Figure 7.
Since various modifications can be made in my inven-tion as hereinabove described, and many apparently widely dif-ferent embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specifi-cation shall be interpreted as illustrative only and not in a limiting sense.
ever~ as this construction is conventional, it is not be-lieved necessary to discuss same further.
This swather unit 11 is mounted within the main r~me 10 by means of members 16 and 17 which extend from the main beam 130 Means may or may not be provided to ad-just the height of the swather unit within the main frame~

This means that the cab can be movad from a straight-ahead swathing position shown in Figures 1 and 2, to a trans-port position shown in Figure 3 which is substc~ntially at 90 from the swathing position shown in Figures 1 and 20 -- 8 ~

naction, a fluid operator 36 is provided extending hatween the main beam 13 and an offstandLng member 37 secured to the rear wheel assembly 22, When in the position shown in Figurs 2, the wheel is fixed in the straight-ahead posi-tion but when the fluid operator is extended as shown in Figure 3, the wheel swings through approximately 90 as shownO A positive lock (not illustrated) may be provided for these two positions which may take the form of a pin engaging within apertures in the wheel assembly and the main beamc When in the transport position, the front wheel as-sembly is turned by the steering wheel to the position shown in Figure 3 and of course the castoring wheel auto-matically tracks as shownO
The cab may also be moved through approximately 90 to take up the position shown in Figure 3 and the cab may be locked in either position by means of a pin assembly shown schematically in Figure 5 and identified by reference character 38.
This enables the operator to have good vision for transport of the swather, particularly along public 1~77~6 roads and the like.
When in the transport position, the valve control 33 is preferably provided with means whereby all of the power may be directed to the front wheel assembly hydraulic motor 21 from the rear wheel assembly hydraulic motor 21A. This gives approximately twice the power to the front wheel and enables the swather to be driven in transport position, at a speed greater than when in the straightahead swathing position.

Figure 7 shows the rear drive wheel portion of Figure 1 in the steering position for a right hand turn.
Figure 8 is a schematic plan view of the steering mechanism and draft control.
Figure 9 is a ~op plan view of the swather showing the swather section in tandem.
In the embodiment illustrated in Figures 7, 8 and 9, the front steering and drive wheel assembly 18 is mounted upon a relatively short frame section 14A which in turn is pivoted to the front of the forwardly extending frame member 14, by means of vertically situated pivot pin 39 and a fluid operator collectively designated 40 extends between a lug 41 adjacent the rear end of the portion 14~ and an offstanding arm 42 connected to the steering post 19. The fluid operator 40 is connected to the steering wheel in such a manner that rotation of the steer-ing wheel operates an hydraulic valve (not illustrated) which . ~
~..,,~
~3777Z6 controls hydraulic fluid under pressure to the fluid operator 40 thus turning the front wheel in synchronization with the steering wheel.
Figure 8 shows a draft control system in which con-; 5 trol valve 33 is provided with two sections, one operatively connected to the front left drive wheel for variable oil flow control and the other conneted to the rear right wheel for var-iable oil control.
This valve is in the form of a shuttle valve assembly operated by a pair of rods 43 and 44 running substantially parallel with the main frame member 13 and being connected to an actuating plate assembly collectively designated 45 which in turn is pivoted centrally as at 46, to a main control link 47 which in turn is pivoted by one end thereof to the frame member 13 as indicated by reference character 48.
The basic position of this link 47 is controlled by an operating lever 50 within the cab pivoted horizontally adja-cent the lower end thereof as at 51 and connected to lever 47 by means of rod 52~ This rod 52 which includes a spring loaded mounting assembly 53, is connected to the distal end of the link or lever 47 as clearly shown in Figure 8.
The control lever 50 is capable of being set in any one OL three positions. Neutral as shown in Figure 8 under which circumstances the shuttle valves 33 are inoperative, forward in which instance the lever 50 is moved in direction of arrow 52, , ~ ~
7~Z6 and reverse in which the lever 50 is moved in the direction of arrow 53.
The rods 43 and 44 are pivoted to the member 45 one upon each side of the pivot 46, by means of pivots 54 and 55 and an extension 56 extends centrally of the pivots 54 and 55 ;
and in substantial alignment with pivot 46. A link 57 is pivo~
tally connected by one end thereof to portion 56 of pivot 58 ~:
and extends forwardly to be connected to a crank arm 59 by means of pivot 60, the crank arm being pivoted to adjacent the front end of the forward extension 14 of the frame as indicated by reference character 61.
A transport and field position cylinder assembly col-lectively designated 62 is mounted by one end thereof to lugs 63 towards the front end of member 14A with the piston rod 64 being pivotally connected to the other end of the crank link 59 as in-dicated by reference character 65 and this piston and cylinder assembly 62 normally acts as a fixed or rigid link when the swather is in the field position. When the control lever is in the forward or reversed position, and the swather is in the field :
position, the rods 43 and 44 route oil from the pump 34 to the hydraulic motors 21 and 21A thus supplying drive to the swather through the wheel assemblies 18 and 22.
Under these circumstances the draft control system is in the position shown in Figure 8 with the portion 14A being in alignment with the frame member 14.
`~,~"
~ .
, ~7~726 ' However when -the steering wheel is turned to the leEt : or right, the piston and cylinder assembly 40 turns the front wheel 18 around the vertical pivot 19. This applies a draft ~ force to the portion 14A and pivots it slightly around its pivot :~ 5 39 in one direction or the other depending upon the direction of wheel 20, and as indicated by double headed arrow 66. This moves the piston and cylinder assembly 62, which is acting as a rigid link, thus actuating crank link 59 and pivoting lever 45 around its pivot 46 thus moving rod 43 in one direction and rod 44 in the other direction which in turn actuates the shuttle valves 33. As an example iE the swather is turned to the right, then the linkage causes the hydraulic motor 21 to speed up and the hydraulic motor 21A to slow down. If the swather is steer- :
~ ed to the left, then the rods 43 and 44 are reversed thus caus-~ 15 ing the hydraulic motor 21 to slow down and the hydraulic motor ; 21A to speed up thus facilitating the turning of the swather.
. ~ .
If a servere right turn is made then the lever 45 moves suffici.ently to actually reverse the direction of hydraulic motor 21A thus facilitating a right hand turn by backing up the right hand end of the swather.
When the swather is moved to the transport position, piston and cylinder assembly 62 is retracted so that portion 14A
extends at right angles to portion 14 under which circumstances ; an offstanding lug 67 adjacent pivot 65, engages frame member 14 and prevents the draft control from operating as of course there :~ is no necessity to utilize same.
~ 77~6 Figure 9 shows the swather with a right hand exten-sion swather section llA pivoted to one end of the swather sec-tion 11 around pivots 68 which permit the two sections to ar-ticulate in a vertical plane,.
A support wheel assembly 69 is pivotally secured to the frame 14B of the section llA adjacent the distal end thereof and this wheel is steerable by means of link 70 extending between arm 37 o wheel assembly 22 and a similar arm 37A of wheel as-sembly 69 so that the steering of the wheel assemhly 18 when in the field operating position shown in Figure 9, also steers not only wheel assembly 22 but also wheel assembly 69.
This wheel assembly 69 can also be moved to the trans-port position similar to wheel assembly 22.
Due to the width of the -tandem swather assembly illus-trated in Figure 9, a further castor wheel assembly 25A may beprovided adjacent the inner end of the frame 13. Also in this particular structure, the cab 12 is mounted inboard of the or-wardly extending beam 14 with the engine assembly 71 being mount-ed upon the frame between the cab and the forwardly extending member 14.
In conclusion, there are two basic positions which the two drive wheels 20 and 24 of the swather can assume. One is a longitudinal position which is for transport. In this position, the ront wheel functions as the steering wheel and the rear wheel is fixed in the longitudinal position and trails therebe-.
~1771~726 hind.
The other position is the field operating position illustrated in Figure 8. In this position, the front left wheel 20 serves as the main steering wheel~ The sharper the turn, the more the draft control mechanism is activated. In order to make a sharp right turn, the draft control mechanism is designed to reverse the rotation of the right rear wheel 24 and turn that wheel approximately 40 to the right as illustrated in Figure 7, thus drawing the right end of the table back while, at the same time, moving the whole table to the left. These movements im-prove the position of the swather for forward movement after the turn. Essentially the same basic procedures apply to the a sharp left turn as well as right turns. The sharp right turn movement is shown in phantom in Figure 7.
Since various modifications can be made in my inven-tion as hereinabove described, and many apparently widely dif-ferent embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specifi-cation shall be interpreted as illustrative only and not in a limiting sense.
