The frame is configured to support a fluid-carrying conduit of the irrigation system. The first and second spindles each include a generally upright beam. The first height adjustment assembly is rigidly connected to a first side of the frame and movably coupled to the first spindle. The first height adjustment assembly includes a first mechanism configured to raise or lower the first side of the frame relative to the first spindle. The second height adjustment assembly is rigidly connected to a second side of the frame and movably coupled to the second spindle. The second height adjustment assembly includes a second mechanism configured to raise or lower the second side of the frame relative to the second spindle.

The present invention provides a pull-out force compensating gearbox mount for an irrigation machine. According to an exemplary preferred embodiment, the present invention provides a system to counteract pull-out forces by inducing camber into the wheel gearbox and thus the tire. According to a further preferred embodiment, the tire of the present invention preferably begins to camber as a result of excessive pull-out force, with the bottom of the tire moving outwards relative to the top of the tire. This camber action is preferably applied to mitigate the pull-out forces. According to a further preferred embodiment, when excessive pull-out forces are reduced, the tire is then returned to its original position.

By using various feedback data on a sprayer system, such as engine speed, wheel speed, sensed temperatures and/or sensed pressures, an onboard logic controller can be used to fine tune parameters of the driveline system in an automatic calibration process. In one aspect, a controller can drive up engine speed and manipulate electrical current being sent to coils of propel pumps and/or wheel motors as current reaches a point where there is no more change in wheel speed as detected by the system, thereby achieving a. calibration setpoint. Additionally, during the automatic calibration process, the machine as a whole can be monitored with respect to several sensors, such as pressures, temperatures, and the like, so that if any parameter being monitored is out of a predetermined range, the calibration can be stopped and not set.

A drive line arrangement for self-propelled agricultural product applicator includes an engine connected to a remotely mounted pump arrangement by a driveshaft that passes through an axle of a frame of the applicator. The axle includes an axle tube extending transversely across the frame and defining front and rear facing surfaces of the axle tube, and a tubular-shaped tunnel fixedly attached to and extending through the axle from the front to the rear facing surfaces of the axle tube, and defining an internal opening of the tunnel for passage of the driveshaft through the tunnel. The tunnel extends beyond at least one of the front and rear facing surfaces of the axle tube to structurally reinforce the axle tube around the opening in the tunnel.

A self-propelled filling pipe for a liquid manure spreader has a frame, an elongated pipe on the frame having a lower inlet end and an elevated outlet end, at least two wheels mounted on the frame, a caster wheel mounted on the elongated pipe proximate the lower inlet end and a fluid drive system. The fluid drive system includes a hydraulic pump, a first hydraulic circuit connecting the hydraulic pump to a plurality of hydraulic motors drivingly connected to the wheels. The fluid drive system also includes a second hydraulic circuit connecting the hydraulic pump to a hydraulic motor operatively connected to the caster wheel. A prime mover provides power to the hydraulic pump to power the hydraulic motors to rotate the caster wheel thereby steering the filling pipe and/or to drive the wheels thereby propelling the filling pipe on the ground.

An irrigation system includes a series of spaced mobile towers; support structure connecting the mobile towers to each other; a water-carrying conduit supported by the mobile towers and the support structure; and a plurality of water emitters connected to the conduit for delivering water to a ground surface. At least one of the mobile towers includes an integrated motor and wheel assembly for driving the mobile tower. The integrated motor and wheel assembly includes a wheel; a tire, track or other ground-engaging component mounted on the wheel; and a direct drive motor positioned in or adjacent the wheel for directly driving the wheel. The direct drive motor drives the wheel without a drive shaft and right-angle gear boxes.

In one aspect, a system for controlling the torsional output of a hydrostatic transmission of a work vehicle may include pilot-operated first and second valves. The first valve configured to be actuated to a closed position to occlude fluid flow through a first fluid conduit when a pressure within such conduit at a location downstream of the first valve drops below a first threshold. Moreover, the second valve configured to be actuated to a closed position to occlude fluid flow when a pressure within the second fluid conduit at a location downstream of the second valve drops below a second threshold. As such, when one of the first or second valves is actuated to the closed position, an increased flow of fluid is delivered through the other of the first valve or the second valve to increase a torsional output of an associated hydraulic motor.

A chassis frame includes a side rails and cross-members that intersect at a number of intersection points, which collectively define a chassis frame with front and rear portions that define a main support section and an integral engine support section. Each side rail includes a top plate, a bottom plate, and first and second side plates extending between the top and bottom plates. The first and second side plates each have a first end coupled to a bottom surface of the top plate and a second end coupled to the top surface of the bottom plate. Each cross-member includes a top plate, a bottom plate, and first and second side plates extending between the top plate and bottom plates. The first and second side plates each have a first end coupled to a bottom surface of the top plate and a second end coupled to the top surface of the bottom plate. A plurality of gusset portions is formed between the top plates of the side rails and cross-members at each intersection point.

An agricultural machine such as a high clearance sprayer is provided with a hydraulic warm-up system for warming multiple hydraulic circuits. The sprayer includes a parking brake system, a hydraulic system including a parking brake hydraulic circuit and at least one ancillary hydraulic circuit, and a hydraulic warm-up system. The warm-up system includes a warm-up circuit defined by the parking brake hydraulic circuit and the at least one ancillary hydraulic circuit so that oil flows through the parking brake hydraulic circuit into the at least one ancillary hydraulic circuit. As a result of this oil flow, the at least one ancillary hydraulic circuit is warmed to improve functionality of the ancillary hydraulic circuit. Where the parking brake is activated and the sprayer is stationary, oil may be diverted to the ancillary hydraulic circuit.
