SAFETY INFORMATION
Safety is a primary concern in the design and
manufacture of our products. Unfortunately,
our efforts to provide safe equipment can be
wiped out by a single careless act of an
operator.
In addition to the design and configuration of
equipment, hazard control and accident
prevention are dependent upon the awareness, concern, prudence and proper training
of personnel involved in the operation, transport, maintenance and storage of equipment.
It has been said ‘The best safety device is an
informed, careful operator.’ We ask you to be
that kind of an operator.
SAFETY RULES
ATTENTION! BECOME ALERT!
YOUR SAFETY IS INVOLVED!
The designed and tested safety of this equipment
depends on it being operated within the limitations
explained in this manual.
Training
l Safety instructions are important! Read this
manual, the tractor manual and all safety rules.
l Know your controls and how to stop tractor
engine and mower quickly in an emergency.
l Operators must be instructed in and be ca-
pable of the safe operation of the equipment, its
attachments and all controls. Do not allow
anyone to operate this equipment without
proper instructions,
l Keep hands and body away from pressurized
lines. Use paper or cardboard, not body parts
to check for leaks. Hydraulic fluid (oil) under
pressure will penetrate skin causing serious
injury.
l Make sure that all operating and service per-
sonnel know that in the event hydraulic fluid
penetrates skin, it must be surgically removed
within a few hours by a doctor familiar with this
form of injury, or gangrene may result.
l Do not allow children or unqualified persons to
operate equipment.
Page 6
SAFETY INFORMATION
Preparation
l Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hands, hearing and head.
l Ensure that mower is properly mounted, ad-
justed and in good operating condition.
l Remove accumulated debris from mower to
avoid fire hazard.
l Ensure all safety decals are installed and in
good condition. (See Safety Decals section for
location drawing.)
l Ensure shields and guards are properly in-
stalled and in good condition.
l Inspect area to be cut and remove stones,
branches or other hard objects that might be
thrown, causing injury or damage.
Operational Safety
l You may not be able to stop the tractor safely if
the clutch or brake pedal mechanisms are
improperly adjusted, allowing them to contact
mower components.
l When the mower lift stops are installed as
instructed in this manual, properly adjusted
clutch and brake pedal mechanisms will not
contact mower components. You should
frequently check that the tractor clutch and
brake pedal mechanisms are in adjustment.
l If the clutch or brake pedal mechanisms can
contact mower components, do not operate
until properly adjusted.
Do not operate mower unless discharge chute
is installed.
Keep bystanders away from equipment while it
is in operation.
Never direct discharge toward anyone.
Operate only in daylight or good artificial light.
Keep hands and feet away from mower while
tractor engine is running.
l Stay clear of all moving parts.
l If your tractor is equipped with a ROPS, you
must wear your seat belt.
l No riders are allowed on tractor or mower.
l Start engine from operator’s seat after disen-
gaging tractor PTO and placing transmission in
neutral.
l Always sit in tractor seat when starting the
engine or operating controls.
l Disengage power-takeoff, shift tractor into
neutral, and place all controls in neutral before
starting tractor engine.
Make sure area behind you is clear before
operating in reverse.
Do not operate on steep slopes,
Do not stop, start or change directions suddenly on slopes.
Use extreme care and reduce ground speed
on slopes and rough terrain,
l Watch for hidden hazards on the terrain during
operation.
l Stop mower and tractor immediately upon
striking an obstruction. Turn off engine, remove
key, inspect and repair any damage before
resuming operation.
l Before working underneath, raise mower, and
block securely. Hydraulic system leak down
and failure of mechanical or hydraulic system
can cause equipment to drop.
l Disengage power to mower, lower mower to
ground, stop engine, set parking brake and
remove key before dismounting tractor.

l Lower mower to ground or block securely, turn
tractor engine off, before performing any
service or maintenance.
l Never perform service or maintenance with
tractor engine running.
l Before working underneath, raise mower, and
block securely. Hydraulic system leak down
and failure of mechanical or hydraulic system
can cause equipment to drop.
l Keep all persons away from operator control
area while performing adjustments, service or
maintenance.
l Frequently check blades. They should be
sharp, free of nicks and cracks and securely
fastened.
l Use a new Nylok blade bolt when you replace
the blade. Do not substitute any bolt for the
special blade bolt. It is self-locking, meeting the
non-loosening requirements for this applica-
tion.
l Your dealer can supply genuine replacement
blades. Substitute blades may not meet original
equipment specifications and may be dangerous.
l Tighten all bolts, nuts and screws, and check

Front to Back Leveling
1. Set the left and right mower blades so that they
face front and rear. Measure the distance to the
ground from front and rear of blades.
NOTE: This measurement can be made with a
steel tape or by using the Blade Height Gauge, an
optional HONDA part (#07JPJ-75OOlOA) available at your HONDA Multipurpose Tractor Dealer.
With the gauge wheels set at the 2%”
position, and the two outside blades
positioned as shown, the blade height at
points A and B should be 64 - 70 mm (2.52 -
2.76 in). The blade height at points C and D
should be slightly higher by about 3 mm (.l
in). The blade height should be the same for
left and right blades.
2. If distance at front of blade tip is too great or
too small, adjust as follows: (Perform this
before connecting drive belt). Tip up front of
deck with steel pry bar and support front of
deck with wooden block.

right and left front links. Loosen the nuts which
hold the clevis tight. Turn both cievis an equal
number of full turns so that both will be set at
same length.
NOTE: Turning the clevis “OUT” lowers the front
clearance; “IN” raises the clearance Each turn
changes height by just over 1 mm (l/32 in).
4. If right and left blade heights are not equal, add
or subtract turns to make equal.
5. After completing adjustment, tighten nut holding
clevis in place, reinsert clevis pin and secure
with linchpin

l Remove the ignition key to prevent acci-
dental starting.
l Wear heavy gloves to protect your hands
from the mower blades.
l Place a block under the mower deck to
prevent it from lowering unexpectedly.
l Stop the engine, remove the ignition key
and disconnect the spark plug caps.
4. inspect each of the blades for cracks, bending
or signs of wear. The right and center blades
can be seen from under the right side of the
mower deck . The left blade can be seen from
under the left front edge of the mower deck.
Turn the blades 180” to inspect the opposite
side.
28
Page 30
If any of the blades show signs of damage or
excessive wear, a more thorough inspection is
necessary (see Page 25 for Mower Deck Removal). A dull blade can be sharpened, but a
blade that is worn out, bent, cracked or otherwise
damaged must be replaced. If a blade needs
sharpening or replacement, take the mower deck
to your authorized HONDA Multipurpose tractor
dealer. Or if you have the proper tools, you can
remove and install the blade yourself.
Use a genuine HONDA replacement blade
or equivalent.
To reduce the possibiiity of weakening the
blade or causing imbalance or poor cutting
performance, sharpening should be per-
formed by an authorized HONDA Muiti-
purpose Tractor dealer.
5. When you have completed the blade inspection, return the Lowering Speed Adjust knob to
its original position.

NOTE: Both gauge wheels must be set to the
same height.
8. If necessary, remove the nut and bolt from left,
right and center anti-scalping rollers, and set
the anti-scalp rollers for the desired cutting
height. This height is determined by which hole
is used in anti-scalping wheel brackets. As
illustrated, top hole sets height of 1.5 in, middle
hole 2 in and bottom hole 2 l/2 in. Make sure to
set all anti-scalping rollers to same height.

MOWING
Before operating this tractor you should read and
understand the Safety Information on Pages 4-6.
When mowing tall grass, make a first pass with the
deck fully raised. This will help to expose any
hidden obstacles. When you are sure that the area
is completely cleared, mow again at the desired
height.
m] if the tractor should accidentally
get caught on an unseen object (rock, root,
hole, etc.), do not attempt to ride over the
obstruction or turn the steering wheel to free
the mower. These actions can damage the
steering mechanism or the deck.
Mowing Tips
1. Mow at full throttle for best cut quality. The lawn
may not be trimmed uniformly at medium or low
engine speeds.
2. Observe the following when mowing:
4th gear
5/6th gear Normal cutting
7th gear Light cutting or transporting
8th gear
3. If grass is exceptionally tall, set deck to highest
position on first pass, then mow again with
deck set to desired height. Also allow the lawn
to dry thoroughly before you use the mower. To
cut a thick or lush lawn, mow in a lower gear or
cut twice.
4. Always turn counter-clockwise at low ground
speed when cutting close to trees, posts,
sprinklers, wails, etc.
5. Y&J may cut the lawn too short when the lawn is
thick or wet, and/or the ground is soft as the
gauge wheels may sink into soft ground.
Heavy cutting or trimming
Use only for transporting
32
6. Increase the cutting height if the lawn is spindly
and the surface is uneven.
Page 34
CUTTING PATTERNS
These cutting patterns are only recommended for
a flat, level lawn surface.
In a small area
First make 2 or 3 turns in a clockwise direction.
Then turn around and continue cutting in the
reverse direction.
In a large area
The first round of cuts is the key to making a neat
finish. First, make 2 or 3 turns in a clockwise
direction, As you reach the center of the area, turn
to the right and continue cutting in the reversa
direction until you have finished the upper half of
the area. Cut the grass in the remaining half in a
counter-clockwise direction.
OPERATION
Small Area Cuffing Pattern
Mowing unsquars areas
If your mowing area is not square or four-sided,
divide the area into several blocks so you can
mow In a neat mowing pattern.
Overlapping on straightaways
Be sure that each mowing lane overlaps sufficiently. The recommended overlap width is between 4-6 inches or approximately the width of
one of the mower’s front tires.
Overlapping in curves and turns
When cutting in curves and turns, shift to a slower
speed and be sure to overlap the previous cut by
20-50% or approximately half the width of the
mower.

REPLACING THE BELTS
One of the major causes of belt failure is improper
installation. Before a new belt is installed, check
pulley shafts and bearings for wear. Check pulley
grooves for cleanliness. Make sure spindles turn
freely and without wobble. If grooves require
cleaning, moisten a cloth with a non-flammable,
non-toxic degreasing agent or commercial detergent and water.
Avoid excessive force during installation. Do not
use tools to pry belt into pulley groove. Do not roll
belt over pulleys to install. This can cause hidden
damage and premature belt failure.
Drive Belt Replacement
1, Set the rear gauge wheel to 1 -l/2 in. position
(see Wheel Adjustments). Turn Lowering Speed
Adjusting knob counter-clockwise towards

spark plug caps before installing the
mower.
Wear gloves when installing belt. Be care-
ful. Do not allow your fingers to be caught
between belt and pulley.
Use care when installing or removing belt
from spring-loaded idler. Springs store
energy when extended and, if released
suddenly, can cause personal injury.
