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.

Install the Discharge Chute

1. Place the springs into the brackets on the mower

with the hooked ends over the raised back of the

bracket (Fig. 1).

2. Align the discharge chute with the holes in the

brackets and the spring straight ends in the space

under the hinge and above the chute (Fig. 1).

3. Secure the chute to the bracket with bolts

through the discharge chute, springs and

brackets. Secure with lock nuts (Fig. 1).

4. Lift the discharge chute and check that it is

spring loaded and pivots freely to the full down

position.

IMPORTANT: Discharge chute must be

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).

4. Position the tractor and mower side by side, with

the mower on the right–hand side of the tractor.

5. Set the parking brake, raise the attachment lift,

and turn the ignition key to “STOP” to stop the

engine. Remove the ignition key.

6. If you have previously had a snowthrower, blade

or tiller attached to the attachment lift, remove

the two clevis pins on each side of the

attachment lift (Fig. 5).

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’

s attachment

lift arm.

5. Start the tractor.

6. Lower the attachment lift arm fully and adjust

the deck’s position until you can pull out on the

J–pin of the lift arm and slide it into the slot in

the mounting bracket of the mower (Fig. 9).

7. On the driver’s left–hand side, pull out the

attachment lift J–pin and slide it into the slot on

the other mower mounting bracket.

8. After the two J–pins are seated through the

mower’s mounting brackets, using the

attachment lift and your hand on the right front

adjustable mower wheel bracket (Fig. 10),

position the mower so its attachment bar fits into

the mid Attach–A–Maticmount.

POTENTIAL HAZARD

•The “scissor” formed by the mower

mounting brackets and the attachment lift

arm is dangerous.

WHAT CAN HAPPEN

•Hands and fingers can get caught between

the mower parts and the tractor and be

injured.

HOW TO AV

OID THE HAZARD

•Keep hands away from moving parts while

operating the attachment lift.

•Always position the mower with your hand

on the right front mower wheel bracket.

•Never try to position the mower with your

hands on the mower mounting brackets or

below the mower housing.

10. Now raise the rear center wheel on the deck so

that it will not interfere with mowing.

IMPORTANT: Always raise the rear center

wheel before mowing. The mower may

become damaged if the wheel is left in the

down position while mowing.

A. Remove the hairpin cotter from the wheel

rod.

Installation

B. Slide the wheel rod back toward the center

wheel as far as it will go. The end of the

control rod should no longer be in the hole

in the height–of–cut plate (Fig. 12).

C. Then install the hairpin cotter into the

control rod hole closest to the height–of–cut

plate as shown.

11. Turn the (2) front mower wheels parallel to the

tractor.

A. If the mower has not been leveled with the

tractor, set the height of the front wheels to

the highest position from the ground.

B. If the mower has been leveled with the

tractor, refer to Adjusting the Two Front

Wheels, page 17.

12. Set the parking brake, lower the attachment lift,

and turn the ignition key to “STOP” to stop the

engine. Then remove the ignition key.

2. Extend the belt through the center of the pulley

box, between the two pulleys.

3. Release the belt tension release arm on the

pulley box housing and swing it out toward you

(Fig. 16).

4. Remove the tractor’s grille by pulling it straight

out toward you.

POTENTIAL HAZARD

•Components under the hood will be hot if
