AXLEHEIGHTADJUSTMENT
1.To adjust rear axle, stop engine and place drive levers in the neutral lock position, remove spark plug wire.
2.Remove lower belt shield from underside of rear deck for better access to axle adjustment bolts.
3.Loosen axle pivot bolts and axle adjustment bolts. See figure # 1.
4.Place a jack under center of rear deck raise the jack slightly so axle adjustment bolts may be removed.
5.With the jack raise or lower the rear deck to the desired position using the chart to ensure proper height. Reinstall the axle adjustment bolts and tighten.
A tapered punch may be used to help align the holes. See figure #1.
NOTE:
It may be necessary to readjust drive and brake linkages.
NOTE:
To achieve the best quality cut, the blades should be level with the ground or slightly tipped forward
BRAKE/TRACTIONADJUSMENT
1.Disconnect the brake linkage from the brake band arm.
2.With the mower in gear, place the traction levers in the drive position. Firmly pull back on the handles until the tires slide to seat the wheel drive belts into the pulleys.
3.Measure the clearance between the bottom of the traction lever rod and the bottom of the thumb latch slot. It should be between 3/16" to 1/4", but not exceeding 1/ 4". See Figure # 3

4.If the clearance is less than 3/16", disconnect the traction rod from the traction lever by removing the hairpin cotter.
5.Adjust the traction rod to the proper clearance by
screwing it out of the swivel if clearance is less than 3/ 16".
NOTE:
More or less brake pressure may be desired depending on the operator or conditions of operation. To increase pressure tighten the wing nut on the brake linkage.
OPERATORPRESENCESWITCHADJUSTMENT The operator presence switches can be adjusted by loosening the screws on the side of the O.P. lever linkage and sliding the switch up or down. The O.P. switch should have a 1/32" to 1/16" gap between the plunger and the bottom side of the control panel when operator presence levers are released.
BLADESWITCHADJUSTMENT
The blade engagement switch can be adjusted by loosening the screws on the flange under the control panel and moving the switch in or out. The blade switch should be adjusted so the plunger is fully depressed when the engagement lever is fully disengaged.
ADJUSTMENTS-DRIVEBELTS
For all drive belts, tension should be set so that belt vibration is minimized or eliminated when belts are moving during normal operation. A properly tensioned belt should have 1/4" to 3/8" deflection at the center of belt span between pulleys when blades are engaged. Blade drive belt tension is preset at the factory.
NOTE:
DO NOT over tighten belt. Excessive tension will decrease belt and spindle bearing life.
