Checking Mower Level
m–3465
For optimum efficiency, the level of the mower
should be checked at the time of initial installation
and periodically as a check, to ensure that the blades
are 1/8” (3 mm) lower in the front than in the rear.
The mower must be checked and adjusted on a flat
level surface, preferably concrete. Before checking
the mower level, set the air pressure in the front and
rear tires as specified in the tractor operator’s manual.
Place the mower height–of–cut lever to the middle
cut position. Make sure the two adjustable front
wheels are off the ground.

Adjusting the Blade Slope for Transport
Because the attachment lift is used when the PTO
drive is engaged, blade slope in transport must be
adjusted to extend PTO drive belt life. This
adjustment also provides for adequate transport
height. Three steps accomplish this: 1) Making sure
the lift arm cams are in the same position, 2)
Measuring blade slope in its front and rear positions
and 3) Making adjustments if the blade slope is not
within specification.
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.
IMPORTANT: Failure to adjust for blade
slope in transport can result in drive belt
failure and/or insufficient transport height.
1. Check to see that both adjustment cams are
oriented with the indicator toward the pivot point
at the rear of the tractor (Fig. 22).

the rear position.
C. When the blade tip is in the front position,
it should be approximately 1/4” (7 mm)
lower than when it is in the rear position.
6. If it is not, start the tractor, lower the attachment
lift to take pressure off the cams, and turn the
ignition key to “STOP” to stop the engine.
Remove the ignition key.
7. Loosen the cam nuts and equally rotate the
left–hand and right–hand cams down to raise the

for Mowing 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.
Using the Mower 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 assure an acceptable quality-of-cut.
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.
18
Page 21
Operation
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization. Avoid
mowing in reverse.
Mow at Correct Intervals
Normally, mow every 4 days. But remember, grass
grows at different rates at different times. So 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 height setting.
Ground Speed
To improve cut quality, use slower ground speed. For
best operation on average lawns, operate engine at
full throttle while controlling ground speed with
transmission. Tractor should be operated at 2 to 3.5
MPH (3.2 to 5.6 kms/hr) while mowing grass.
Uneven cutting is often a result of excessive ground
speed. To correct, use low range with the high–low
lever, or reduce ground speed in high range.
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.
2. To disperse the clippings evenly, raise the mower
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.
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 uneven turf is not cut too short. Average
lawns are usually cut at a height between 2 and 3
inches (5–7.6 cm).
Long Grass
If the grass is ever allowed to grow slightly 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.
