  • Work vehicle with hydraulic assist for power off steering
    Patent number: 9867325
    Abstract: A steering system for a work vehicle includes a steering hand pump, a hydraulic main supply line fluidly coupled with the steering hand pump and including a check valve, and a normally open, two position valve. The valve includes an inlet fluidly couplable with a pressurized access point of a hydraulic sub-system, an outlet fluidly coupled with the main supply line on a downstream side of the check valve, and a pilot port fluidly coupled with the main supply line on an upstream side of the check valve. The valve is operable in the closed position based on pressure in the main supply line when the main supply line is pressurized from a pressure source, and operable in the open position and interconnecting the pressurized access point with the main supply line through the outlet when the main supply line is not pressurized from the pressure source.

  • System for determining counter knife bank insertion position
    Patent number: 8141805
    Abstract: A chopper assembly for a combine includes a rotary chopper element, a chopper grate assembly spaced from the rotary chopper element to form a passageway for crop residue and a knife bank adjustably connected to the chopper grate assembly. The knife bank is movable between a first position where the knife bank is fully inserted into the passageway and a second position where the knife bank is full retracted from the passageway. An actuating mechanism is used to move the knife bank between the first position and the second position. A position sensor is used to measure the position of the actuating mechanism and determine the position of the knife bank relative to the passageway.
