MOWING SPEED __________________________________________________________

Cutting quality is better at speeds well below the transport
speed of the tractor. An initial mow speed of 5 -6 MPH (8 -10
kph) is set at the factory and should be satisfactory for most
cutting conditions. Local turf conditions however may
respond better to a different speed. If an adjustment is
needed, refer to the Parts and Maintenance manual.
4.9

TOWING / TRAILERING _____________________________________________________

If the tractor experiences problems and must be shut down
and removed from the area, it should be loaded onto a trailer
for transport. If a trailer is not available, the unit can be
towed slowly short distances.
Use care when loading and unloading tractor. Fasten tractor
to trailer to prevent tractor from rolling or shifting during
transport.
Before towing, open tow valve. The tow valve permits
moving the tractor without starting the engine and prevents
possible damage to hydraulic components.
Note: On machines equipped with four wheel drive (4WD)
the tractor will tow easier if the ignition is turned to RUN (do
not start engine) and the 4WD switch is set to 4WD.
The tow valve (A) is located on the hydraulic drive pump
beneath the operators seat. Remove cover from floor in front
of operator's seat. To open valve, use a wrench or insert a
pin or small screw driver into the small hole in the valve
stem. Turn the valve counterclockwise one full turn.

4.10 HILLSIDE OPERATION _____________________________________________________

!
WARNING
To minimize the possibility of overturning, the safest
method for operating on hills and terraces is to travel up
and down the face of the slope (vertically), not across the
face (horizontally). Avoid unnecessary turns, travel at
reduced speeds, and stay alert for hidden hazards.
CAUTION:
Do not operate this tractor on slopes
!
greater than 22°.
The tractor has been designed for good traction and stability
under normal mowing conditions; however, use caution
when operating on slopes, especially when the grass is wet.
Wet grass reduces traction and steering control.
Before towing make sure cutting units are raised. If they
cannot be raised, remove them from the tractor.
Close valve completely and replace cover after towing.
NOTE: Do not exceed 2 MPH (3.2 KPH) while towing. Long
distance towing is not recommended

Correct tire pressure is essential for maximum traction. See
Parts & Maintenance Maunal
A
Always mow with the engine at full throttle but reduce
forward speed to maintain the proper cutting frequency.
If the tractor tends to slide or the tires begin to "mark"
the turf, angle tractor into a less steep grade until
traction is regained or tire marking stops.
If tractor continues to slide or mark the turf, the grade
is too steep for safe operation. Do not make another
attempt to climb, back down slowly.
When descending a steep slope, always lower
implements to the ground to reduce the risk of tractor
overturning.
