Lowering the Hopper

When the hopper lift lever is moved to the LOWER position, hydraulic fluid flow
is directed to the hopper lift cylinders. The hydraulic pressure in the rod side of
the cylinder causes the piston to retract and lowers the hopper. When the lift
cylinders reach the end of their stroke, the relief valve in the steering control
valve opens and directs the hydraulic flow to the pump until the lift lever is
returned to the neutral position.
