MOWING SPEED __________________________________________________________
Cutting quality is better at speeds well below the transport
speed of the mower. An initial mow speed of 7 MPH (11 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 & Maintenance manual.
4.9
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.

4.10 TOWING / TRAILERING _____________________________________________________
If the mower 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.
A
Use care when loading and unloading mower. Fasten mower
to trailer to prevent mower from rolling or shifting during
transport.
Before towing, open tow valve. The tow valve permits
moving the mower without starting the engine and prevents
possible damage to hydraulic components.
LF006
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.
Rotate brake release lever (B) counter clockwise. Brake
release lever is located under access panel, near right front
axle mount. Turn steering wheel for right hand turn
(clockwise) until resistance is felt.
Before towing make sure cutting units are raised. If they
cannot be raised, remove them from the mower.
Close tow valve (A) completely, rotate brake release lever
(B) clockwise, and replace cover after towing.

QUALITY OF CUT
5.1
QUALITY OF CUT TROUBLESHOOTING _______________________________________
It is recommended that a “test cut” be performed to
evaluate the mower’s performance before beginning
repairs.
An area should be available where “test cuts” can be
made. This area should provide known and consistent
turf conditions to allow accurate evaluation of the
mower’s performance.
Another “test cut” should be performed after the
completion of the repairs and/or adjustments to verify the
mower’s performance.
Before performing a “test cut” to diagnose cut
appearance and mower performance, the following items
should be verified to ensure an accurate “test cut.”
5.2
1. Mowing (Ground) Speed.
2. Reel Bearing Condition and Pre-Load (End Play)
Adjustment.
3. Reel and Bedknife Sharpness.
4. Bedknife Alignment to Reel.
5. Reel-to-Bedknife Contact.
6. Height-of-Cut (HOC).
7. Roller and Roller Bearing Condition.
WASHBOARDING__________________________________________________________
Washboarding is a cyclical pattern of varying cutting
heights, resulting in a wave-like cut appearance. In most
cases, the wave tip-to-tip distance is approximately
6—8 in. (15—20 cm). Color variation (light-to-dark) may
also be noticed.
This condition is usually caused by a rocking motion in
the cutting unit(s). This condition is found mostly on
mowers with multiple (suspended) cutting units, but other
causes can produce the same result.
Washboarding may also be caused by variations in the
turf.
TN0159
NOTE: Arrow indicates direction of travel.
Probable Cause
Remedy
Mowing (ground) speed is too fast.
Reduce mowing (ground) speed.
Grass build-up on roller.
Clean the roller and use scrapers or brushes.
