Setup & Adjustments
BRAKE / TRACTION ADJUSMENT
1.Disconnect the brake linkage from the brake band arm.
2.With the mower in gear, place the drive levers in the drive position. Firmly pull back on the handles until the tires slide to seat the drive belts into the pulleys.
3.Measure the distance between the back drive lever slot and the neutral bail. It should be between 3/16 and 1/4" but not exceeding 1/4". See Figure #3.
4.If the clearance is less than 3/16”, disconnect the drive lever from the idler arm by removing the retaining ring.
5.Adjust the drive linkage to the proper clear- ance by screwing it into the yoke at the drive lever end of the linkage. This will achieve proper clearance if the distance is less than 3/16”. Screw the linkage out if it is greater than 1/4".

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.
OPERATOR PRESENCE SWITCH ADJUST- MENT
The operator presence switches can be ad- justed by loosening the screws on the back side of the console and sliding the switch left or right. The O.P. switch plunger should just come in contact with the O.P. lever when the operator presence levers are released.
BLADE SWITCH ADJUSTMENT
The blade engagement switch can be adjusted by loosening the screws on the blade engage- ment bracket and moving the switch up or down. The blade switch should be adjusted so the plunger is fully depressed when the engage- ment lever is fully disengaged.
ADJUSTMENTS - DRIVE BELTS
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.
BLADE DRIVE BELT ADJUSTMENTS
WARNING
BEFORE PERFORMING ADJUSTMENTS ON BLADE BELT, TURN MOWER OFF, CLOSE FUEL VALVE, AND DISCONNECT SPARK PLUG WIRE.
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
5.Tighten whiz nut on turnbuckle and install belt shield.
