WHEEL DRIVE ADJUSTMENTS Drive Belt Guard See Figure 27 DANGER: Avoid injury from rotating blade.
Wheel Drive Speed Adjustment The wheel drive lower belt connects the mower blade shaft to a variable speed (VS) pulley. Wheel drive speed is determined by how deep the wheel drive lower belt rides in the VS pulley. The higher the belt rides in the VS pulley groove, the slower the wheel drive speed. The lower the belt rides in the VS pulley groove, the faster the wheel drive speed. See Figures 24 and 25. 1. Remove both the upper and lower guards. See WHEEL DRIVE ADJUSTMENTS Drive Belt Guard on page 23. 2.
Wheel Drive Traction Adjustment The gap (clearance) between the drive rollers and tires, when wheel drive is disengaged, is used to set the amount of contact force (traction) when wheel drive is engaged. Drive roller to wheel gap should be 1/8" – 1/4" (3mm – 6mm). NOTE: A smaller gap between rollers and tires when wheel drive is disengaged provides for more engaged traction, which is helpful on sloped terrain.
