7. Install the spring anchor eye bolt into the spring anchor
tab and loosely fasten the adjustment nut.
8. Tighten the nut until the spring (M) achieves a coil-to-coil
measurement of 6-3/4" (17,15 cm).
9. Tighten the jam nut.
10. Install the clutch anchor pad to the PTO clutch and
secure using the hardware previously removed. Connect
the wire harness to the PTO clutch.
11. Install the mower belt. See Long Left Hand Deck Belt
Replacement for installation instructions.
Suspension Adjustment
The shock assemblies (A, Figure 68) can be adjusted to allow
the operator to customize the ride according to the operator's
weight and/or operating conditions.
68
The front shock assemblies can be adjusted by changing the
spring's pre-load.
The rear shock assemblies can be adjusted by changing the
spring's pre-load and/or upper mounting position.
A spanner wrench (B) was included with the literature packet
that came with this unit. The spanner wrench is used to adjust
the spring's pre-load.
Items to consider before adjusting the suspension:
• Less spring pre-load should be used with light weight
operators, which will provide a softer, more cushioned
ride.
• More spring pre-load should be used with heavy weight
operator's, which will provide a stiffer, more rigid ride.
• There are three positions in which the upper shock
mount can be positioned to. If adjusting the spring's pre-
load does not achieve the ride requirement, the shock
should be moved to the next higher numbered upper
shock mounting position to achieve the desired ride
requirement.
• Before adjusting the upper shock mount to a higher
numbered position you should attempt to achieve the ride
height through the spring's pre-load adjustment.
• Shock mounting position #3 should always be used when
a rear-mounted grass collection system is installed on the
unit.
To Adjust the Spring Pre-load:
This procedure details the process for adjusting the spring's
pre-load for the rear shocks. To adjust the spring's pre-load
for the front shocks only steps #1 and #5 are required.
The shock's pre-load adjustment consists of rotating the pre-
load adjuster (A, Figure 69) with a spanner wrench so that the
adjuster rides either up or down on the shock's fixed point (B)
into one of the adjuster's five notch positions. As the adjuster
moves up towards the spring, the spring is more compressed
which creates more spring load. As the adjuster moves down
away from the spring, the spring is less compressed creating
less spring pre-load.

1. Park the unit on a flat, level surface such as a concrete
floor. Disengage the PTO, engage the parking brake, and
turn the ignition switch to OFF to stop the engine.
2. Chock the front wheels to prevent the unit from rolling.
3. Raise the rear of the unit and secure with jack stands.
4. Remove the rear drive tires.
