As previously described, when the lift switch is neither in the R
position, fluid pressure shifts the logic cartridge LC open to provide a fluid path to
the tank. When the lift switch is set to the L
is energized to open a path for fluid trapped behind the lift cylinder pistons to
escape through the open logic cartridge LC as well.
The weight of the cutting deck or implement causes the cylinders to retract thus
lowering the cutting deck or implement. As the cylinders retract, the pistons
draw hydraulic fluid from the reservoir (front axle) into the lower (rod end) of
the lift cylinders.
