Brush Mower
Service Adjustments
DANGER: Before making any adjustments or servicing
your brush mower, make sure the brush mower is on
level ground, the blades are disengaged, the key is
removed, the engine is off and the spark plug wires are
disconnected from the spark plugs to prevent
accidental contact. If maintenance or adjustments are
being performed after operation of the brush mower,
allow the unit to cool since heat build up could cause
severe burns.
Engine-to-Blade Belt Adjustment
1. Remove the deck cover and move the blade control
lever on the control console to the ON position.
2. With approximately 10 pounds of pressure, push
the clutch pulley to tighten the belt. The linkage
should stop approximately 1 inch before contacting
the stop bolt. If the belt moves more than ½-inch,
move the blade control lever back to the OFF
position.
3. Loosen locking nut.
4. Rotate turnbuckle until desired tension is achieved
(approximately 1 inch from stop bolt).
5. Tighten locking nut when finished.
6. Replace
deck
cover.

IMPORTANT! The brush mower blades do NOT stop
quickly. Visual indication that the blades are turning
is provided at the center of the belt guard. DO NOT
approach the brush mower deck for service,
cleaning, removing debris, or for any other reason
until after the visual warning disk has stopped
completely. Even at slow speeds the blades can
cause serious injury or death.

Engine-to-Hydrostatic Drive Belt Adjustment
1. The engine-to-hydrostatic drives belt is located
underneath the rear deck. The belt should move
approximately 5/16-inch to 3/4-inch with three (3)
to five (5) pounds of pressure applied to the belt
midway between the transmission pulley and the
engine output shaft pulley.
When installing a new belt, the tension should be
higher than the running tension. It is not necessary
to keep the belt at the greatest (smallest
deflection) tension during normal operation.
Important: Do not over-tighten the belt.
2. To adjust the
belt, turn the
nut on the
threaded
tension rod
found on the
right, rear
corner of the
mower.
3. Do not over-tighten. This could cause serious
damage to the hydraulic drive systems.
