6.4—REAR MOWER LIFT
The rear mower lift height has been preset at the factory and
normally will not need to be adjusted.
The I-Trim may be
fitted with a needle valve on the rear lift cylinder.
Turning the needle valve CW will slow the lift and
lowering speed of the rear deck. Always lock the
adjusment knob down when done adjusting.

6.5—HEIGHT OF CUT ADJUSTMENT
1. To set the height of cut, lift the
deck to a vertical position (Fig.
O). Remove linch pins and assemble spacers (1 Fig. 0) to set
height of cut desired. Loosen side attachmement bolts of rear
roller if needed to slide rear roller out (2 Fig. O). Min HOC is 1.5”
with no spacers under the roller attachment shaft. Max HOC is
4”
Rollers must be adjusted to the same height so
that there will be uniform cutting the entire width
of the mower.
To avoid possible serious bodily injury, before
performing and adjustments, maintenance, or lu-
brication, place all controls in “neutral”, lower
the mowers to the ground, engage parking brake,
turn ignition switch off and remove key.
Use heavy gloves and be careful. Blades are
very sharp.
2. Make sure adjustment nuts are tight before
mowing.

6.6—BLADE REPLACEMENT PROCE-
DURE
Replace blades with factory blades only. Standard discharge
blades and mulching blades are available. Note: The Rear
and Right decks use the same blade (RH). The Left deck uses
a LH blade.
Be extremely careful not to let tools, your fingers
or clothing get caught in the blades. Use ap-
proved safety glasses to protect eyes from flying
particles and abrasives.
NEVER START ENGINE WITH DECKS ROTATED
UP AND NOT IN A HORIZONTAL POSITION.
1. Loosen 1/2-13 Grade 8 bolts and remove blades. Install
new blades as shown in Fig. O. Make sure cutting edge is
closest to ground and correct blade is on each deck.
2. Install bolts and torque to 98 ft-lbs. If needed, replace
