The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by sitting on the seat in the normal operator’s
position.

POTENTIAL HAZARD
•Without the discharge chute mounted in
place, you and others are exposed to blade
contact and thrown debris.
WHAT CAN HAPPEN
•Contact with rotating mower blade(s) and
thrown debris will cause injury or death.
HOW TO AV
OID THE HAZARD
• NEVER r emove the discharge chute from
the mower because the discharge chute
routes material down toward the turf. If
the discharge chute is ever damaged,
replace it immediately. Never put your
hands or feet under the mower.
•Never try to clear the discharge area or
mower blades unless you move the power
take off (PTO) to “OFF” and turn the
ignition key to “STOP.” Also remove the
ignition key and pull the wire(s) off the
spark plug(s).
Mower Belt Routing
1. Route the mower belt as shown in Fig. 2. Be
sure to install the belt on the lower mower deck
pulley.

Installing the Mower
Initial Preparation
The mower must be installed on a level concrete
surface. Rough dirt or lawn surfaces make
installation much more difficult.
1. Place the height–of–cut lever on the deck to the
position for lowest cut (Fig. 3).

2. Lower the rear center wheel (if not already
lowered). Do this by:
A. Removing the hairpin cotter from the wheel
rod (Fig. 4).
B. Lifting the rear of the deck.
C. Pulling the rod toward the outside of the
mower, inserting the end of the rod into the
hole in the height–of–cut plate (Fig. 4), and
then installing the hairpin cotter into the
second hole of the wheel rod as shown
(Fig. 4).
3. Set the height of the (2) front mower wheels and
turn the wheels parallel to the mower by
removing the clevis pins and hairpin cotters,
then turning and raising or lowering the wheels
until you can put the clevis pins and hairpin
cotters in the third position from the top (Fig. 3).

2. Make sure the front mower wheels are turned
parallel to the mower and the rear center wheel is
lowered (Fig. 3).
3. From the driver’s right–hand side of the tractor,
slide the mower under the tractor. Once the
mower is almost under the tractor, you may need
to turn the steering wheel to the left to provide
enough room for the mower to slide completely
under the tractor.
4. After sliding the mower under the tractor,
position it so that the slots in the side of each of
the mower’s mounting brackets (Fig. 8) are
aligned directly below the tractor’
