Always set the parking brake, shut off power
unit engine, remove the ignition key, and ensure
all moving parts have come to a complete stop
before inspecting components or attempting any
repair or adjustment.
Attention
If any component requires replacement, use only
original Ventrac replacement parts.

Cleaning and General Maintenance

For best results, and to maintain the finish of the
mower deck, clean or wash the mower to remove
accumulated clippings, leaves, and dirt when the job is
finished. Refer to the "Deck Flip-up procedure" in the
service section to access the underside of the deck.
If washing the deck, do not spray directly into bearings
or seals. After washing, it is important to run the mower
so that water does not reside on seals of bearings for
the drive system. When washing is complete, return
the deck to the operating position and activate the PTO
for 30 seconds to remove any standing water.

Mower Blade Inspection/Replacement

Mower blades may be sharp. Always wear
heavy gloves when working with mower blades.
1. Rotate the mower deck up to the service posi-
tion following the deck flip-up procedure.
2. Inspect the mower blades to ensure cutting edges
are sharp. If blades are dull or damaged, they
must be removed and sharpened or replaced.
3. Place a short piece of 2 x 4 wood between the
end of the blade and an appropriate structural
part of the underside of the deck to prevent the
blade from rotating.
4. Loosen the blade bolt counterclockwise and
remove the blade for sharpening or replace-
ment.
5. When installing a blade, the wood block must be
placed on the opposite side to prevent rotation
for tightening the blade bolt.
6. Torque the blade bolt to 75-80 ft-lbs (102-108 Nm).

Mower Blade Sharpening

Blades should be sharpened and balanced by a pro-
fessional. Maintain balance, same bevel, and length
of sharpened surface.

Belt Inspection/Replacement

Inspecting the drive belts of the mower can prevent
sudden belt failure by finding problems before they
cause a belt to break. Typical wear on a drive belt
may result in the conditions shown in the diagram.
