1. Park the rider on a smooth, level surface such as a
concrete floor. Disengage the PTO, engage the
parking brake, turn off the engine, and remove the
ignition key.
2. Remove the PTO drive belt (see MOWER BELT

3. Loosen the nut towards the front of the machine on
the spring anchor hook (H, Figure 35) to release the
majority of the belt tension. Use caution and remove
the nut to completely release the tension.

Make sure the V-side of the belt runs in the grooves
of the crankshaft pulley and pump pulleys (B & C).

loosely fasten the nut. Adjust the spring until a
measurement of 7-3/4” (19,7cm) is achieved from the
outside of the spring hooks. Tighten nut.
