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

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
NOTE:
DO NOT over tighten belt. Excessive tension will decrease belt and spindle bearing life.

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.
1.Remove front deck belt shield.
2.Loosen whiz nut on turnbuckle.
3.Set belt tension when engagement lever is in the engaged position.
4.To increase belt tension rotate turnbuckle toward the rear of the mower until desired tension is gained. Do not over tighten belts, to much tension will reduce belt and spindle bearing life. See figure # 6
