Set-up Instructions
ADJUST THE TURF
COMPENSATION SPRING
The turf compensation spring (Fig. 5), connecting the
carrier frame to the cutting unit controls the amount of
fore-aft rotation available, and the amount of ground
clearance in transport and turn around.
The turf compensation spring also transfers weight from
the front to the rear roller. This helps reduce a wave
pattern in the turf.
IMPORTANT: Make spring adjustments with the
cutting unit mounted to the traction unit and lowered
to the shop floor. Refer to the traction unit operator's
manual for mounting instructions.
1.
Tighten the lock nut on the rear of the spring rod
until the gap (C) between the rear of the spring
bracket and front of the washer is 1/2" (13 mm)
(Fig. 5).
2.
Tighten the hex nuts on the front end of the spring
rod until the compressed length (A) of the spring is
8" (203 mm) (Fig. 5).
NOTE: When cutting rough or undulating turf,
increase the compressed length (A) of the spring to
B=1/2" (216 mm) and the gap (C) between the rear
of the spring bracket and the front of the washer to
1-1/4" (32 mm) (Fig. 5).
NOTE: As the compressed spring length (A)
DECREASES, weight transfer from the front roller
to the rear roller INCREASES and the carrier
frame/cutting unit rotation angle (B) DECREASES.
NOTE: As the gap (C) between the spring bracket
and washer INCREASES, cutting unit ground
clearance DECREASES and the carrier
frame/cutting unit rotation angle (B) INCREASES.
