concrete floor. Disengage the PTO, engage the park-
ing brake, turn off the engine, and remove the ignition
key.
2. Remove the PTO drive belt (see MOWER BELT

the spring anchor hook (H, Figure 38) 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).
5. Reinstall the anchor hook (H) into the anchor tab and
loosely fasten the nut. Adjust the spring until a meas-
urement of 7-3/4" (19,7cm) is achieved from the out-
side if the spring hooks. Tighten nut.
6. Reinstall the PTO drive belt.
