A vehicle has a pair of opposite drive wheels driven by a dual path hydrostatic transmission. Steering and speed/direction controls are effected by changing the displacement and/or direction of fluid flow through the pair of reversible, variable displacement pumps that are respectively coupled to fixed displacement ground wheel drive motors. The control mechanism for accomplishing steering and/or speed/direction control includes a steering rack that is caused to pivot about a fixed post in response to steering wheel movement. A first crank arm is coupled for pivoting in concert with the rack and a second crank arm is coupled for pivoting in concert with a pivot plate about a second axis, the pivot plate having a pair of connection points respectively coupled to control arms of the pair of pumps by a pair of pump control rods. The pivotal motion of the steering rack is transmitted to the pivot plate by a tie-rod coupled between the first and second crank arms. This tie-rod is parallel to a pivot support bar that swings about the fixed post in response to fore-and-aft movement of a speed/direction control lever, the pivot plate being pivotally mounted to the free end of the pivot support bar.

A steering and ground speed control mechanism of a vehicle equipped with a dual-path hydrostatic drive system includes a pivot plate fixed to a vertical pivot post at a location between and equidistant from a pair of locations respectively linked to a pair of pump displacement control arms of a pair of pumps respectively coupled for delivering fluid to right- and left-hand drive motors coupled to right- and left-hand ground wheels. A train of elements for transferring steering inputs from a steering wheel to the pivot plate includes a timed belt and sprocket set with one of the sprockets being fixed to the pivot post and the other mounted to a fixed post together with a quadrant-shaped steering rack for pivotal movement about the fixed post in concert with the rack. Pivoting the pivot plate in opposite directions from a centered position causes different displacements of the pumps and, hence, in the two drive motors being driven at different speeds. A train of elements for transferring speed inputs from a speed control lever to shift the pivot plate back and forth in a nearly straight path includes a push-pull cable coupled between the lever and an arm having the pivot post pivotally mounted in one end thereof, with the arm being mounted for pivoting about the fixed post exclusive of the rack and sprocket.

A self-propelled windrower is provided with a platform including a reel which sweeps crop to be cut over a sickle cutterbar and into the nip of a pair of counter-rotating center-feed augers that, in turn, deliver the crop to the nip of a pair of counter-rotating conditioner rolls; and these driven components may be reversed to disgorge slugs of crop. The reversible drive includes a hydraulic pump carried by the traction unit and coupled to a motor carried by the platform. The hydraulic motor on the platform is coupled to power a main gear box which distributes power to the driven components of the platform. Operation of the pump is electro-hydraulically controlled with a single switch being operable to effect forward operation of the platform drive train, and with a second switch being designed to be moved and held in place to effect and maintain the drive train in reverse. Both switches cannot be operated at the same time, however the machine can be reversed with the platform lowered, fully raised, or anywhere in between.

An agricultural implement includes a header or platform suspended from a main frame by a suspension permitting movement of the header between a lowered working position and a raised transport position. The suspension includes single-acting float cylinders and a single-acting lift cylinder controlled by an electrohydraulic control system including a programmable microprocessor in which a signal representative of a minimum acceptable float pressure may be set. The microprocessor contains an electronic switch that couples a warning device lead to ground to effect energization of the warning device in response to the microprocessor receiving an electronic signal representative of a float circuit pressure below the minimum acceptable float pressure. In one embodiment, the microprocessor contains a timing device which is triggered whenever a control switch is connected to energize a "lower" signal lead the timing device being set to time out when sufficient time has elapsed to ensure that the header has reached its working position. The timing device works to suppress the signal representative of the float circuit pressure so that a premature energization of the warning device does not occur when a low float pressure is due to the header being elevated from the ground.

An agricultural harvester includes a traction unit and a crop harvesting header coupled with the traction unit. The header includes a main frame with a right hand (RH) side and a left hand (LH) side. A RH gauge wheel is movably coupled with the RH side of the main frame, and a RH hydraulic cylinder is coupled between the RH gauge wheel and the main frame. A first hydraulic circuit is coupled with the RH hydraulic cylinder and configured to control an operating height of the RH gauge wheel. A LH gauge wheel is movably coupled with the LH side of the main frame, and a LH hydraulic cylinder is coupled between the LH gauge wheel and the main frame. A second hydraulic circuit is coupled with the LH hydraulic cylinder and configured to control an operating height of the LH gauge wheel. The second hydraulic circuit is independent from the first hydraulic circuit. A third hydraulic circuit is coupled with a vertical position hydraulic cylinder and configured to operate at a predetermined operating pressure, whereby a portion of the weight of the header is carried by the traction unit.

An agricultural windrower includes a traction unit having a frame. A cutting platform has a longitudinal extension, a feeder opening associated with a first mounting location, and a first hitch at an end of the cutting platform associated with a second mounting location. A lift assembly carried by the traction unit frame is configured to mount with the cutting platform at the first mounting location. An articulated transport arrangement is mounted to the traction unit frame. The articulated transport arrangement includes a second hitch configured for mating with the first hitch, and at least one actuator for coupling between and adjusting a relative angular orientation between the frame and the cutting platform when the first hitch and the second hitch are mated together.

A dual-path hydrostatic drive arrangement for driving ground wheels at the opposite sides of the front of a self-propelled windrower is controlled for effecting steering and ground speed changes by a control mechanism including a gear train defined by a steering input gear and idler gear and steering output gears carried by a gear support member mounted for pivoting about a fixed axis of rotation of the input gear. The output gear is coupled for transmitting movement to first and second pump displacement control rods and steering is effected by turning a steering wheel which is coupled for rotating the input gear so as to impart rotation to the output gear which rotates so as to cause the control rods to move different amounts or in different directions. Speed changes are effected by a speed control device that is coupled for selectively swinging the speed/direction control arm.

A vehicle has a parking brake system including spring-applied, pressure-released brakes. An electrohydraulic control system is provided for selectively energizing a solenoid-operated brake control valve so that release pressure is supplied to the brakes when the transmission control lever is not in neutral or when the vehicle tachometer is indicating a ground speed other than zero.
