An agricultural apparatus including an agricultural vehicle and a number of work units suitable for cutting a standing crop. The work units include a front work unit and two lateral work units located behind and to the sides of the front work unit, each of the work units depositing cut crop as a swath. Each of the lateral work units is supported from a central chassis by a hydraulic system. A plurality of sensors determine a speed of the agricultural vehicle, a speed of operation of each lateral work unit and a relief pressure in the hydraulic system of each lateral work unit. A control unit is configured to receive inputs from the plurality of sensors, compare the values for a desired vehicle speed or speed of operation of the mower unit and adjust the pressure relief in the hydraulic system based on this comparison. The inertia of the hydraulic control system can accordingly be compensated for and the work units are able to follow the terrain contour, resulting in an even cut.

An adjustable lift rate system on a grass mowing machine such as a riding greensmower having a lift and lower circuit including a plurality of hydraulic lift cylinders to lift and lower a plurality of cutting units, and a controller providing a current to a proportional solenoid valve to bypass the hydraulic lift cylinders. An operator control may be used to adjust the current to the proportional solenoid valve to adjust the lift and lower rate of the cutting units.

A draper header includes a draper frame and a reel arm. The reel arm is coupled to a reel and pivotally coupled to the draper frame. The draper header further includes a cutterbar pivotally coupled to the draper frame. The reel arm and the cutterbar are configured to pivot about the draper frame to adjust a side profile aspect ratio of the draper header from a first aspect ratio to a second aspect ratio. A height of the first aspect ratio is less than a height of the second aspect ratio, and a width of the first aspect ratio is greater than a width of the second aspect ratio.

An agricultural harvester, such as a combine harvester, which has an auxiliary axle assembly for support of the feeder house of the harvester. The auxiliary axle assembly can be provided in a retracted position when in a field mode, and can be locked in an extended position when in a road mode, where a wheel of the assembly contacts the ground. When in the locked, extended position, the auxiliary axle assembly supports substantially all of the weight of the feeder house and any attached implements, allowing the feeder house to pivot relative to the main chassis of the harvester.

A riding lawn care vehicle may include a frame, an engine, a steering assembly, a support platform and a front platform. At least a pair of drive wheels may be operably coupled to the frame. The engine is operably coupled to the frame via an engine platform. The engine is disposed between the drive wheels to selectively provide drive power to the drive wheels via respective hydraulic pumps. The steering assembly includes control levers operably coupled to respective drive wheels via the respective hydraulic pumps. The steering assembly enables steering of the lawn care vehicle based on drive speed control of the drive wheels responsive to positioning of the control levers. The support platform is operably coupled to the frame at a rear portion of the lawn care vehicle. The front platform is operably coupled to the frame forward of the engine platform. The front platform supports the hydraulic pumps.
