* The key switch must be on.
* The neutral latches must be in the neutral lock position.
MOWER OPERATION (CONT'D)
3.
Start the engine:
* Choke as required. If the engine is cold, pull the
choke knob out. When the engine starts, slowly
push the choke in. If the engine stalls, repeat the
above operation. When the engine is warm,
choking may not be necessary.
4. Engage the cutter blades by depressing the operator
presence levers and pulling the blade clutch switch
into the ON position. Push the switch to the OFF
position to disengage the cutter blades.
* The parking brake must be on.
* Cold starting. In the spring and fall when the
morning temperatures are cool it may be difficult
to start the machine due to the parastatic load
from the hydraulic drive. To relieve this load, pull
out and up on the de-clutch chain located on the
right side of the machine behind the tire. This will
allow you to start the engine easily. When the
engine is warmed up, slowly release the de-
clutch chain to engage the hydraulic system.
5. Engage the cutter blades by pulling the blade clutch
switch into the ON position. Push the switch to the
OFF position to disengage the cutter blades.

PUSH DOWN TO DISENGAGE
-NOTE-
When PTO is engaged or (possibly) disengaged,
a squealing sound from the underside of the
machine is normal. It is caused by the electric
clutch plates meshing as the mower comes up to
speed. For best equipment life, engage the
clutch with the engine at 3/4 throttle, not under
full load.
WARNING:
If you are not familiar with the operation of the
hydrostatic drive and zero turn feature, practice
turning and maneuvering with the hand controls
before engaging the cutter blades.
7. While squeezing the steering brake levers with both
hands, release both neutral latches.
-NOTE-
Top speed is suggested only for transport!
6. Release the parking brake. Move the speed adjust-
ment lever to the desired mowing speed.
8. When the steering brake levers are released, the
machine will travel straight. To make a right turn,
squeeze the RH lever. To turn left, squeeze the LH
lever.
9. TO STOP, squeeze both levers, lock the neutral
latches, and move the speed adjustment lever to
neutral.
10. To move the machine in reverse, squeeze up on both
steering control levers.
11. To "freewheel" or move the machine around
without the engine running, turn the dump valve
levers located at the back of the pumps to the
"freewheel" positions (see Figure 1). To operate
the machine, the dump valve levers must be
returned to the closed positions.
