MAINTENANCE
! CAUTION !
Before per
forming any maintenance work, turn OFF
engine, remove key and disconnect Spark Plugs. Use
extreme care when working on machinery. Do not wear
loose fitting clothes, and observe all common safety
practices with tools. Also let all hydraulic and engine
parts cool before servicing any filters or engine parts.
! BATTERY WARNING !
AVOID SERIOUS INJURY OR DEATH:
THE BATTERY CONTAINS SULFURIC ACID.
AVOID CONTACT WITH SKIN, EYES OR
CLOTHING.
LEVELING THE DECK:
The deck comes from the manufacturer pre-
leveled. If the deck does not appear to be cutting
level, follow this procedure.
1. Set all tire pressures to correct specification.
2. Place machine on a level cutting surface and
inspect blades to make sure that one is not
damaged or bent.
3. Stop engine and Remove the ignition key.
While wearing heavy gloves rotate the blades
so that they are all pointing to the forward side
of the deck. (See fig.1) Measure from the
blade tip to the ground on all three blades. If
there is more than 3/16" difference from one
side of the deck to the other, the deck should
be leveled.
4. To adjust the deck height, remove the clevis
pin from the lift spring rod. This may be
accomplished by moving the lift arm to a point
that relieves the pressure off the pin. (See fig.
2) To raise the deck, thread the back of the
spring rod clockwise. To lower the deck, turn
the spring rod counter clockwise (Note: That
when changing the length of the spring rod do
so in two turn increments). At this time also
inspect the bushings or washers, at the base
of the spring (by the spring bolt) and check for
binding.

5. Reassemble the spring rod and replace the
clevis pin. Now move the deck up and down
and recheck the side to side blade
measurement.
BELT ADJUSMENT:
Remove the key from ignition switch. Flip up the
floor plate (See fig. 3) to gain access to the deck
drive belt and the eyebolt assembly that is used
for adjusting the spring tension. The spring tension
is measured by the gap between the coils and
should be approximately 1/8". By turning the 5/
16" nylock nut on the end of the eyebolt clockwise,
it will increase tension. Moving the deck bracket
into the second slot (See fig. 3) may also increase
tension.
