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.

Installing the Carrier Frame to
the Traction Unit
1. Fasten the angle brackets to the traction unit
frame with the six (6) 1/2”-13 x 1” (25 mm) hex
head flange bolts and flange locknuts. Position
the bottom locknuts on the outside of the angle
brackets. Torque the fasteners to 60–80 ft-lbs
(81–109 NM) (Fig. 2).
IMPORTANT: When installing the angle
brackets on traction units with hydrostatic
drive, use the 1/2”-13 x 1-1/4” hex head flange
bolts supplied with the traction unit.
2. Attach the carrier frame to the angle brackets
with the four (4) 3/8”-16 x 1-3/4” (44 mm) hex
head bolts and locknuts. Note that the locknuts
must be on the outside of the carrier frame.
Leave the locknuts loose to allow movement
between the carrier frame and angle brackets
(Fig 2).
3. Install the shims between the carrier frame and
angle brackets. Align the holes in the shims with
the top holes in the carrier frame and angle
brackets (Fig. 2).
4. Install the four (4) 3/8”-16 x 7/8” (22 mm) hex
head screws with flat washers through the carrier
frame and shims, and into the threaded holes in
the top of the angle brackets. Torque the hex
head screws to 27–33 ft.-lb (37–45 Nm)
(Fig. 2).
5. Tighten the four (4) 3/8”-16 x 1-3/4” (44 mm)
hex head bolts and locknuts. Torque to 27–33
ft-lb (37–45 Nm) (Fig. 2).

Installing the Cutting Deck
1. Position the cutting deck under the carrier frame.
2. Mount the cutting deck to the carrier frame with
four (4) clevis pins and hairpin cotters (Fig. 3).
Note: All four pins must be in the same hole
locations to prevent uneven cutting.

Installing the Drive Belt
1. Remove the deck cover from the top of the
cutting deck.
2. Install the drive belt around the traction unit
drive pulley and the top pulley on the left
spindle. The belt must be to the left of the belt
guide (Fig. 4).

4. Slide a 1/2” washer, spring and bushing onto
each adjusting shaft. Make sure to install the
bushing with the flange end against the spring
(Fig. 5).

the hole in the deck mounting bracket. Note that
the small end of the bushing fits into the hole in
the deck bracket. Insert the locknut end of the
adjusting shaft into the carrier frame mounting
tab (Fig. 6).
6. To tension the belt, tighten the front jam nut on
each adjusting shaft until the springs are
compressed to 5” (12.7 cm). Measure the spring
compression between the spacer and the bushing
(Fig. 6). Readjust if needed.
7. Tighten the rear jam nuts (Fig. 6).

Operation
Side Discharge or Mulch Grass
The mower has a hinged grass deflector that disperses
clippings to the side and down toward the turf.
POTENTIAL HAZARD
•Without the grass deflector or complete
grass catcher assembly 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 AVOID THE HAZARD
•NEVER remove the grass deflector from
the mower because the grass deflector
routes material down toward the turf. If the
grass deflector is ever damaged, replace it
immediately.
•Never put your hands or feet under the
mower.
•Never try to clear discharge area or mower
blades unless you move the power take-off
(PTO) to “OFF” and rotate the ignition key
to “OFF.” Also remove the key and pull the
wire(s) off the spark plug(s).
Engaging the Mower Blades
(PTO)
The blade control switch (PTO) in conjunction with
the blade control bail engages and disengages power
to the electric clutch and mower blades.
1. Move the blade control bail to the upper control
bar to stop the machine (Fig. 8).
2. To engage the blades, squeeze the blade control
bail against the upper control bar (Fig. 8).
3. Press the blade control rocker switch forward to
“ON” then release the switch. You must be
holding the blade control bail against the control
bar while operating.
Note: Repeat the procedure to engage the
mower blades if the blade control bail
is released.
4. To disengage the blades, release the blade
control bail (Fig. 8).
