1. Deck lift switch
The deck lift/lower switch is used to raise and lower the cutting deck on later
machines. The switch is located on the control panel
The engine must be running to allow the cutting deck to be raised or lowered.
When the front of the lift switch is pressed, the deck will lower fully. When the
rear of the lift switch is pressed and held, the deck will raise. When raising the
deck, the deck will remain in position if the switch is released.
When the rear of the lift/lower switch is pressed, both of the solenoid valve coils
(SV1 and SV2) on the hydraulic lift control valve are energized causing the
valves to shift and the lift cylinder to extend to raise the cutting deck. When the
front of the lift/lower switch is pressed, solenoid valve coil (SV2) on the hydraulic
lift control valve is energized causing the valve to shift and the lift cylinder to
retract to lower the cutting deck.
1. Park the machine on a level surface, lower the cutting deck, set the parking
brake, and shut off the engine.
2. Ensure that the key switch is in the O
from the key switch.
3. Remove the 4 thumb screws (item 2 in
