could result in serious injury or death.
Stop engine, remove key, allow all the moving
parts to stop before accessing the drive wheel
release valves.

very hot. Touching a hot engine or hydraulic
drive components can cause severe burns.

PTO Engagement Switch
Located behind the RED Equipped LDU on the RH
console (see Figure 7).
Switch must be "ON" (pulled up) to engage the
blades. Switch is "OFF" (pushed down) to disengage
the blades.
The LCD indicator will appear on the information
screen of the RED Equipped LDU when the PTO
switch is disengaged.
Note: Engaging and disengaging the PTO switch
changes the engine throttle between "mow" and
"transport" mode.
Note: The starter will crank with the PTO switch in
the "ON" (pulled up) position; however, the system
will disengage the PTO and a PTO reset error will
occur. Engaging the PTO will require the operator to
reset the PTO switch by turning it "OFF" (pushed
down) and then turning it "ON".
Important: On 96 inch Decks: The wings must
be unfolded before the PTO can be engaged.
