! WARNING !
Do not attempt to straighten a bent blade or weld
a broken or cracked blade. Always replace it with
a new blade to assure safety.
If a blade cutting edge is dull or nicked, it should
be sharpened. Remove the blades for sharpening.
Raise cutter deck to transport position. Lift the
front of unit using jack stands or equivalent
support making sure that the machine is secure.
Clean out any grass build-up from the underside
of the deck and in deck discharge chute.
Remove or install the blades by placing a block of
wood between the front or rear baffles and the
blade. When replacing the blade bolt be sure the
spring disk washer cone is installed toward the
bolt head (See fig. 1).
NOTE: Always balance the blade after sharpening.
CUTTER DECK GEARBOX:
CAUTION
The cutter deck gearbox can reach high operating
temperatures. Allow the cutter deck gearbox to
cool before servicing.
CHECKING LUBRICANT LEVELS:
CAUTION
The fluid level in the gear box should be checked
after every 100 hours of operation or bi-weekly,
which ever occurs first.
Remove ignition key and raise deck to transport
position. Clean and remove the check plug from
the side of the gearbox. Visually check that the
lubricant level is up to the bottom edge of the
check-plug hole. If lubricant is low, add SAE
80W90 lubricant through the check-plug hole.
Install the check plug and tighten securely.
The lubricant in the cutter deck gearbox should be
changed after every 500 hours of operation or
yearly, whichever occurs first.
Place a suitable container beneath the cutter deck
gearbox and locate the gearbox drain plug.
Remove the drain plug, drain the lubricant into the
container and properly discard it.
Reinstall the drain plug and add SAE 80w90
lubricant through the check-plug in the gearbox,
until it is level with the bottom of the check-plug
hole. Install the check plug and tighten securely.
HYDRAULIC SYSTEM:
The hydraulic oil should be changed after every
500 hours or annually, which ever comes first. The
oil should also be changed if the color of the fluid
has become black or milky. A black color and/or a
rancid odor usually indicates possible over heating
of the oil, and a milky color usually indicates water
in the hydraulic oil.
Park mower on a level surface and stop the
engine. Place a suitable container under the
hydraulic oil reservoir. Remove the fill cap from the
reservoir. Remove the drain plug from the bottom
of the tank and allow oil to drain into the container.
While the reservoir is draining replace the
hydraulic filter.
Replace the drain plug and fill reservoir to sight
glass (located in the rear side of the tank) with
20W50 motor oil. This will require approximately
7qts of oil.
! WARNING !
To avoid serious Burn injuries:
Allow engine, and hydraulic fluids to cool before
servicing transmission or engine systems.
