FRONT SUSPENSION ADJUSTMENT
The shock assembly can be adjusted to vary the amount
of pre-load applied to the springs. This allows the oper-
ator to customize the ride according to operator’s weight
and/or operating conditions.
Less Pre-Load:
• Light operator weight
• Softer, more cushioned ride
• Best for relatively flat terrain
More Pre-Load:
• Heavy operator weight
• Stiffer, more rigid ride
• Better handling and greater stability on hilly terrain
To adjust the spring pre-load:
1. Park machine on a flat, level surface. Disengage the
PTO, stop the engine and engage the parking brake.
2. See Figure 23. Using the supplied spanner wrench
(p/n 22853), insert the tip of the wrench into the
notch in the pre-load adjuster. While holding the
wrench in place with one hand, turn CLOCKWISE to
increase the pre-load, turn COUNTER-CLOCKWISE
to decrease the pre-load. Make sure both shocks
are set to the same amount of pre-load.
NOTE: Spanner wrench is located behind the rear seat
cross member, on the left-hand side of the machine.
REAR SUSPENSION ADJUSTMENT
If the rider tilts either side-to-side or front-to-rear, this
adjustment will level the frame with the ground.
Although this adjustment may not be necessary, it may
be required if additional weight (ie. a grass catcher) is
added to the frame or a drive tire is replaced.
NOTE: Perform this adjustment on a hard, level surface
such as a concrete floor.
Measure the distance between the ground and the bot-
tom of the frame, behind the drive tires. This should
measure 9-3/4” (24,7 cm) for both sides for 25hp model;
10-1/4” (26 cm) for 27hp model. If it does not, loosen
the jam nut (B, Figure 24) and turn turn the height
adjustment bolt (A) COUNTER-CLOCKWISE to lower
the corresponding side of the frame, and CLOCKWISE
to raise the frame. Tighten the jam nuts.

WARNING
Use two hands when adjusting the shock springs.
This will prevent the wrench from slipping while
pressure is being applied.
