Tension
Check the PTO drive belt tension after 5 hours of
operating with a new belt, then every 50 hours or
once a year, whichever occurs first.

pulley box. If the tension indicators are not in
the same position on both the left and right
sides, release the belt tension and turn the
adjustment knob. Push the belt tension release
arm back toward the pulley box to tension the
belt

same position.
3. Once the indicators are in the same position on
both sides, swing the tension release arm into the
pulley box by moving it into the position shown
in Fig. 35.
