Adjusting Turf Compensation Spring - Toro 5 Operator's Manual

Set–Up
Adjusting Turf Compensation
Spring
The Turf Compensation Spring (Fig. 2), connecting
carrier frame to cutting unit, controls the amount of
fore-aft rotation available, as well as the amount of
ground clearance in transport and turn around.
The Turf Compensation Spring also 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. Refer to Traction Unit
Operator's Manual for mounting
instructions.
1. Tighten lock nut on rear of spring rod until the
gap (C) between rear of spring bracket and front
of washer is 1" (26 mm) (Fig. 2).
2. Tighten hex nuts on front end of spring rod until
the compressed length (A) of spring is 8" (203
mm) (Fig. 2).
Note: When cutting rough or undulating turf,
increase compressed length (A) of
spring to 8-1/2" (216 mm) and gap (C)
between rear of spring bracket and
front of washer to 1-1/2" (39 mm)
(Fig. 2).
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.
