Operating Instructions
42
Engaging the Debris Blower
1. Set the engine throttle at about 1/3 speed. DO
NOT attempt to engage the PTO clutch at
high engine speeds. This will drastically short-
en drive belt life. Use only moderate engine
speed when engaging the PTO clutch.
2. Pull the PTO clutch lever SLOWLY to engage
the debris blower.
NOTE: For cold weather operation, allow suffi-
cient time for the debris blower components to
warm up before beginning to blow debris.
IMPORTANT: DO NOT engage the PTO
clutch when transporting the machine. DO NOT
engage the PTO clutch with the PTO shaft
disconnected (the debris blower removed from
the tractor).
Recommendations For Operating the Debris
Blower
IMPORTANT: Operate the engine at full speed
when operating the debris blower, to allow the en-
gine to produce full horsepower and to increase ef-
ficiency of the engine cooling system.
•
When operating on a slope, reduce speed and
use caution to start, stop, and maneuver. Avoid
sharp turns or sudden changes in direction.
•
Use optional tire chains or optional all-terrain tires
to improve traction.
•
Disengage the PTO clutch to stop the debris
blower when driving the machine but not operating
the debris blower.
•
Avoid damage to property and extra cleaning
work by carefully choosing the direction to move
the debris. Orient the blower away from people and
property due to the possibility of thrown objects.
•
To momentarily increase traction in case the drive
wheels are slipping, use the lift switch to raise the
debris blower slightly and transfer extra weight on
the drive wheels.
STOPPING THE MACHINE
1. Slow the engine to idle; put the throttle in the
IDLE position.
2. Pull the steering levers to the NEUTRAL posi-
tion and then move the FSC lever backward to
the NEUTRAL-PARK position.
3. Disengage the PTO clutch.
IMPORTANT: DO NOT disengage the PTO
clutch with high engine speed (above 1/2 throt-
tle) since the brake action on the PTO drive will
cause premature wear of the brake band.
4. Turn the ignition switch OFF.
5. Engage the parking brake.
IMPORTANT: The hydrostatic transmissions
lock to prevent the machine from rolling freely
with the engine stopped. However, if the ma-
chine is parked on a slope, it is necessary to
ENGAGE the parking BRAKE to prevent the
machine from creeping. This is due to a small
amount of slippage in the hydrostatic transmis-
sions, especially when transmission fluid is
warm.
WARNING
A safety interlock switch (seat switch) will
cause the engine to stop if the PTO clutch
is engaged and the operator is not in the
seat. The function of this switch should
be checked by the operator raising off the
seat and engaging the PTO clutch; the en-
gine should stop. If the switch is not
working, it should be repaired or replaced
before operating the debris blower. DO
NOT disconnect the safety switches; they
are for the operator’s protection.
WARNING
A brake stops the machine from free-
wheeling within five (5) seconds after dis-
engaging the PTO clutch. If the brake
system malfunctions and the machine
does not stop within five (5) seconds, the
brake should be adjusted or repaired be-
fore operating the machine. Refer to the
appropriate Tractor Owner’s Manual for
adjustment procedures.
WARNING
Remove the key from the ignition switch
when leaving the machine unattended.
This will prevent children and inexperi-
enced operators from starting the engine.
