ENGINE MUST BE OFF AND
IGNITION KEY REMOVED BEFORE
CHECKING BELT TENSION. ALL
PARTS MUST BE COMPLETELY
STOPPED. ALLOW ALL PARTS TO
COOL COMPLETELY TO PREVENT
BURNS. CLUTCH MUST BE
DISENGAGED.
• Insert a screwdriver or metal bar (a
metal ruler would be good) through the
slot to check belt tension.
• Make a mark on the screwdriver or
metal when it touches the belt without
any force applied and then apply force
and make another mark.
• Measure the distance between the two
marks. If the measurement is more than
3/4”, the belt tension needs to be
adjusted. If the measurement is much
less than 3/4”, the belt tension is too
tight and needs to be adjusted.
• Do not over tighten the engine belt. An
overly tight belt will cause damage to
PTO/clutch bearings and to cutter drum
bearings.
ADJUST BELT TENSION
• There are four engine slide bolts (3/4”)
mounting the engine to the frame. There
are also two eyebolts for adjustment,
which are mounted to the two engine
slide bolts at the front of the machine to
move the engine and adjust the belt
tension.
• Loosen all four of the engine slide bolts
enough to be able to move the engine but
don’t remove the bolts. The bolts are
secured through a block under the frame
and will require only one wrench to
loosen.
