The cutting deck position switches are normally open proximity switches that
interact with sensing plates as the cutting deck lift arms raise and lower. When a
cutting deck is in the lowered position, the sensing plate will be near the position
switch and the switch will be closed. When a cutting deck is raised, the sensing
plate is moved away from the position switch and the switch opens.
The cutting deck position switches are attached to brackets on the traction unit
frame. The sensing plates are attached to the lift arms.
The slave controller monitors the position of the cutting deck position switches.
Using inputs from the position switches, the engine and coolant temperature
senders, the high/low range traction speed switch and the seat switch, the slave
controller energizes hydraulic solenoid valves PRV in the cutting deck control
hydraulic manifolds as necessary to engage the cutting blades.
