• Best for relatively flat terrain. 38 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 unit on a flat, level surface. Disengage the PTO, pivot the ground speed control levers out to the NEUTRAL position, and stop the engine. 2. Turn the pre-load adjustment collar (B, Figure 39) with your hand to a higher notch (-) to decrease the pre-load, or to a lower notch (+) to increase the pre-load. 2. Tilt the back end of the floor pan up and then remove it from the unit. 3. To install the floor pan: reverse the removal procedure. Neutral Adjustment The neutral system for this unit is a function of the transaxles. 1. Drive the unit to a flat, level surface. Engage the parking brake and disengage the PTO. 2. Without touching the ground speed control levers disengage the parking brake. If the unit moves, the neutral systems on the transaxles are not correctly adjusted. See your authorized STIHL servicing dealer. Suspension Adjustment The shock assemblies (A, Figure 39 - front shown, rear similar) can be adjusted to vary the amount of pre-load applied to the springs. This allows the operator to customize the ride according to operator's weight and operating conditions. 39 Parking Brake Adjustment The parking brake is not adjustable. If the parking brake does not function properly, do not use the zero-turn riding mower! See your authorized STIHL servicing dealer to have the parking brake serviced. Mower Deck Removal and Installation Removing the mower deck makes deck maintenance items easier to perform. 1. Park the unit on a flat, level surface such as a concrete floor. Engage the parking brake, disengage the PTO, turn the ignition switch to OFF, and remove the ignition key. 2. Remove the mower deck drive belt as described in Mower Deck Drive Belt Replacement. 3. Place blocking underneath the mower deck. 4. Lower the mower deck to its lowest cutting height to relieve the pressure on the mower deck mounting hardware. 5. Remove the hardware that connects the puller bar (A, Figure 40) to the front deck mount (B) to disconnect the puller bar from the unit. 40 Less Pre-Load: • Light operator weight. • Softer, more cushioned ride. 33
