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.

Height Adjustment
Transport height is set at the factory and should not
need adjustment; however if the belt covers contact
the footrest in the raised position, adjustment is
required.
1. Adjust by turning transport height nut, (Fig. 9)
on lift mechanism, clockwise to raise or
counterclockwise to lower mower.
2. Adjust nut until there is 1/16–1/8 inch clearance
between belt cover and left footrest.

Side-to-Side
Mower Leveling
The mower blades must be level from side to side.
Check the side-to-side level any time you install the
mower or when you see an uneven cut on your lawn.
Before you level the mower, set the air pressure in the
front and rear tires to 12 psi (.85 kPa).
3” to 4” Height-of-Cut Range
When the mower height-of-cut is set to the 3” to 4”
range the mower is suspended from the tractor. The
side-to-side adjustment for this height range is made
as follows;
1. Park the tractor on a flat surface, disengage the
power take off (PTO), set the parking brake, and
turn the ignition key to “OFF” to stop the
engine. Remove the key.
2. Raise attachment lift lever all the way to the
latched position.

If the front blade tip is not 0–1/8” (0–3.2 mm) lower
than the rear blade tip, adjust the blade slope using
the following instructions:
1. Park the tractor on a flat surface, disengage the
power take off (PTO), set the parking brake, and
turn the ignition key to “OFF” to stop the
engine. Remove the key.
2. Check and adjust side-to-side blade level if you
have not checked the setting; refer to

3. Adjust the Dial-A-Height knob so the
height-of-cut is in the middle of the range and
lower attachment lift.
4. Carefully rotate blades so they are facing front
and rear (Fig. 13).
6. To adjust front-to rear blade level loosen jam nut
on front adjustable link. (Fig. 14).
7. Rotate the bolt on front adjustable link to change

Operation
Tips
for Mowing and Recycling
Grass
Fast Throttle Setting
For best mowing and maximum air circulation,
operate the engine at “FAST.” Air is required to
thoroughly cut grass clippings, so do not set the
height-of-cut so low, as to totally surround the mower
by uncut grass. Always try to have one side of the
mower free from uncut grass, which allows air to be
drawn into the mower.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure the
cutting height of the mower does not scalp any
uneven ground. However, the cutting height used in
the past is generally the best one to use. When cutting
grass longer than six inches tall, you may want to cut
the lawn twice to ensure an acceptable quality-of-cut.
Avoid Cutting Too Low
If the cutting width of the mower is wider than the
mower you previously used, raise the cutting height
to ensure that uneven turf is not cut too short.
Long Grass
If the grass is allowed to grow longer than normal, or
if it contains a high degree of moisture, raise the
cutting height higher than usual and cut the grass at
this setting. Then cut the grass again using the lower,
normal setting.
When Stopping
If the machine’s forward motion must be stopped
while mowing, a clump of grass clippings may drop
onto your lawn. To avoid this:
1. With the blade(s) “ENGAGED,” move onto a
previously cut area.
Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended, unless
grass is sparse or it is late fall when grass grows more
slowly.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization.
Mow at Correct Intervals
Normally, mow every 4 days, but remember that
grass grows at different rates at different times. To
maintain the same cutting height, which is a good
practice, mow more often in early spring. As the
grass growth rate slows in mid summer, mow less
frequently. If you cannot mow for an extended period,
first mow at a high cutting height; then mow again 2
days later at a lower setting.
2. To disperse the clippings evenly, raise the mower
one or two height-of-cut settings while driving
forward with the blade(s) “ENGAGED.”
Keep the Underside of the Mower Clean
Clean clippings and dirt from the underside of the
mower after each use. If grass and dirt build up inside
the mower, cutting quality will eventually become
unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding
turns grass brown at the edges, which slows growth
and increases the chance of disease. Every 30 days,
check the cutter blade(s) for sharpness and file down
any nicks.

Maintenance
Cutting
Blade
To ensure a superior quality of cut, keep the blade(s)
sharp. For convenient sharpening and replacement,
you may want to have an extra blade(s).
POTENTIAL HAZARD
• A blade that is worn or damaged could
break apart and pieces could be thrown at
bystanders or at you as you use the mower.
WHAT CAN HAPPEN
• Pieces of blade that may be thrown could
seriously injure or kill you or bystanders.
HOW TO AV
OID THE HAZARD
• Periodically inspect the blade for wear and
damage. Immediately install a new blade if
it is worn or damaged.

Inspecting the Blade(s)
1. Remove the mower; refer to Removing the
Mower, page 10.
2. Inspect the cutting edges (Fig. 22). If the edges
are not sharp or have nicks, remove the blade(s)
and sharpen them; refer to Sharpening the
Blade(s), page 17.
3. Inspect the blade(s), especially the curved area
(Fig. 22). If you notice any damage, wear, or a
slot forming in this area (Fig. 22), immediately
install a new blade.
2. Carefully tip the mower over.
3. Remove the bolt (5/8” wrench), washer, retainer
and blade (Fig. 23). A block of wood may be
wedged between the blade and the mower to
lock the blade when you are removing the bolt.
4. Inspect all parts. If a defect or damage is noticed,
install new parts.

Maintenance
Sharpening the Blade(s)
1. Use a file to sharpen the cutting edge at both
ends of the blade (Fig. 24). Maintain the original
angle. The blade retains its balance if the same
amount of material is removed from both cutting
edges.

Sharpen
at original angle
2. Check the balance of the blade by putting it on a
blade balancer (Fig. 25). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
metal off the back side of the blade. Repeat this
procedure until the blade is balanced.
Installing the Blade(s)
1. Install the blade, blade retainer, washer, and the
blade bolt (Fig. 26).
IMPORTANT: The curved part of the blade
must be pointing up to ensure proper cutting.
2. Tighten the blade bolt to 45–60 ft–lb
(61–81 Nm).

prevent grass build-up for improved recycling and
clipping dispersal.
1. Park the machine on a hard, level surface,
disengage the power take off (PTO) and turn the
ignition key to “OFF” to stop the engine.
2. Screw coupling to the end of a garden hose,
attach coupling to mower washout fitting and
turn water on high (Fig. 29).
Note: Spread petroleum jelly on washout
fitting o-ring to make coupling slide on
easier and protect o-ring.
3. Lower the mower to the lowest height-of-cut.
4. Sit on the seat and start the engine. Engage
power take off (PTO) and let mower run for one
to three minutes.
5. Disengage the power take off (PTO) and turn the
ignition key to “OFF” to stop the engine.
6. Turn the water off, remove coupling from the
washout fitting and hose.
Note: If the mower is not clean after one
washing, soak and let stand for 30
minutes. Then repeat process again.
7. Run mower again for one to three minutes to
