mulated around mandrels and entire upper deck surface.

drel pulleys (R) and all idler pulleys (V).

TO CHECK BRAKE
If tractor requires more than five (5) feet to stop at highest
speed in high est gear on a level, dry concrete or paved
surface, then brake must be serviced.
You may also check brake by:
•
Park tractor on a level, dry concrete or paved surface,
depress brake pedal all the way down and engage
parking brake.
SERVICE AND ADJUSTMENTS
• Disengage transmission by placing freewheel control
in “transmission disengaged” position. Pull freewheel
control out and into the slot and release so it is held in
the disengaged position.
The rear wheels must lock and skid when you try to manu-
ally push the tractor forward. If the rear wheels rotate,
then the brake needs to be serviced. Contact a qualified
service center.
TO LEVEL MOWER
Make sure tires are properly inflated to the PSI shown on
tires. If tires are over or under inflated, it may affect the
appearance of your lawn and lead you to think the mower
is not adjusted properly.
VISUAL SIDE-TO-SIDE ADJUSTMENT (See Fig. 33)
•
With all tires properly inflated and if your lawn appears
unevenly cut, determine which side of mower is cutting
lower.
NOTE: As desired, you can raise the low side of mower
or lower the high side.
• Go to side of mower you wish to adjust.
• With a 3/4" or adjustable wrench, turn lift link adjust-
ment nut (A) to the left to lower the mower, or, to the
right to raise the mower.
NOTE: Each full turn of adjustment nut will change mower
height about 3/16".
• Test your adjustment by mowing some uncut grass
and visually checking the appearance. Readjust, if
necessary, until you are satisfied with the results.

ground or driveway.
CAUTION: Blades are sharp. Protect
your hands with gloves and/or wrap
blade with heavy cloth.
• Raise mower to its highest position.
• At both sides of mower, position blade at side and
measure the distance (A) from bottom edge of blade
to the ground. The distance should be the same on
