8. Coat the spline of the reel motor with clean grease.
9. Oil the reel motor O-ring and install it onto the
motor flange.
10. Install the motor by rotating it clockwise so that
the motor flanges clear the cap screws (Figure 20).
Rotate the motor counterclockwise until the flanges
encircle the cap screws then tighten the cap screws
Important: Make sure the reel motor hoses
are not twisted, kinked or in the risk of being
pinched.

Note: If fixed cutting unit position is required,
insert steering locking pin into pivot knuckle
mounting hole (Figure 18).
11. Hook spring wire around bottom of steering locking
pin (Figure 18).

Adjust the Turf Compensation Spring
Tractors are setup at the factory appropriately for most
fairway mowing applications.
The following adjustments are available for fine-tuning
of the machine to the application:
The Turf Compensation Spring (Figure 21) transfers
weight from the front to rear roller. This helps to reduce
a wave pattern in the turf, also known as bobbing.
Important: Make spring adjustments with cutting
unit mounted to traction unit and lowered to shop
floor.
1. Tighten lock nut on rear of spring rod until the
gap (C) between rear of spring bracket and front of
washer is 2 in. (51 mm) (Figure 21).
2. Tighten hex nuts on front end of spring rod until
the compressed length (A) of spring is 6.25in. (159
mm) (Figure 21).
Note: When operating on rough terrain, decrease
the spring length by 1/2 inch. Ground following will
be slightly decreased.
Note: As compressed spring length (A) decreases,
weight transfer from front roller to rear roller
increases and carrier frame/cutting unit rotation
angle (B) decreases.
Note: As gap (C) between spring bracket and
washer increases, cutting unit ground clearance
decreases and carrier frame/cutting unit rotation
angle (B) increases.
Note: When cutting undulating turf, increase the
compressed spring length (A) and the gap width (C)
1/2 inch (Figure 21).
