BELT ADJUSTMENT

The best tension for a V-belt drive is the lowest tension at which the belts will not slip under normal load condition. Check the tension on a new belt frequently during first hours of operation and every 10-15 hours or monthly thereafter. Too much tension shortens belt and bearing life. Too little tension causes slippage and loss of power. Be sure that belts and pulleys are kept free of foreign material. If belt slippage occurs, tighten it just enough to prevent slippage.

TRANSAXLE DRIVE BELT

To adjust tension, loosen 4 bolts which hold engine to mount and belt keeper in place. Loosen tension bolt located at rear of machine. Adjust tension bolt until desired tension is achieved, tighten 4 bolts holding engine and tighten tension bolt lock nut.

MOWER DRIVE BELT

Belt tension for mower drive belt is adjusted by loosening nut on mower deck turnbuckle assembly and turning turnbuckle to achieve desired tension. Retighten nut. Tension should be checked with belt in engaged position.

REPLACE BELTS WHEN ADJUSTMENT CAN NO LONGER BE MADE SATISFACTORILY OR IF BELTS BECOME WORN.
