Replacing Engine Belt
 Slide the engine back toward the cutter wheel
with the engagement handle as far as it will go,
then remove the belt and put on the new belt.
 After replacing the belt, check it for tension.
Slide the engine forward to engage the belt.
The belt should deflect 3/8" with 25 lbs. of
force centered between the pulleys. New belts
will stretch and become loose as machine runs.
Check belt tension often when belts are new.
 If any adjustment is required, there is a linkage
assembly below the engagement handle on the
operator side. Loosen jam nut and adjust clevis
with wrench turning up toward machine. This
will make engine slide further and will tighten
the belt. Make only slight adjustments at a time
and recheck tension; repeat as necessary until
tension is correct. When proper tension is
achieved, tighten jam nut back onto clevis.
 Use this same procedure to tighten loose belts.
 DO NOT OVER TIGHTEN BELT; OVERLY
TIGHT BELTS WILL CAUSE BEARING
AND ENGINE DAMAGE. Turn the clevis
down with a wrench if the belt is too tight.
 Replace belts when worn or when repeated
adjustments are necessary. Belts should never
get so loose that all of the adjustment capability
is used.
 If the belt tension was adjusted, the engine slide
lock will also have to be adjusted. This locks
the engine in the disengaged position so that the
cutter wheel will not accidentally engage.
When adjusting the engine slide lock, turn the
clevis clockwise to shorten the length of the
engine slide lock when the engagement linkage
was lengthened. The engagement linkage
would be lengthened to put more tension on the
belt. Lengthen the engine slide lock if the
engagement linkage was shortened.
