TO STOP ENGINE AND BLADE
1. Move throttle control lever to SLOW position.
2. Release the blade control handle to stop the
engine and blade.
WARNING: The blade continues to
rotate for a few seconds after the engine is
shut off.
3. Disconnect the spark plug wire and ground it
against the engine to prevent accidental starting
while equipment is unattended.
USING YOUR ROTARY MOWER
Be sure that lawn is clear of stones, sticks, wire, or
other objects which could damage lawn mower or
engine. Such objects could be accidently thrown by
the mower in any direction and cause serious
personal injury to the operator and others.
For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings, and
could cause you to slip and fall. New grass, thick
grass or wet grass may require a narrower cut.
Blade speed should be adjusted to the condition of
the lawn.
The best mowing pattern is one that allows the
clippings to discharge towards the uncut part of the
lawn. This permits recutting of the clippings to
further pulverize them. When cutting high weeds,
discharge towards cut portion, then recut at right
angles to first direction.
For a healthy lawn, always cut off one-third or less
of the total length of the grass. Lawn should be cut
in the fall as long as there is growth.
This mower is designed to be operated at full
throttle to give you the best cut and do the most
effective job of bagging the cut grass.
WARNING: If you strike a foreign
object, stop the engine. Remove wire from
spark plug, thoroughly inspect the mower
for any damage, and repair the damage
before restarting and operating the mower.
Extensive vibration of the mower during
operation is an indication of damage. The
unit should be promptly inspected and
repaired. See Safety labels in Figure 1.
SECTION 7: ADJUSTMENTS
WARNING: Do not at any time make
any adjustment to lawn mower without first
stopping engine and disconnecting spark
plug wire.
CUTTING HEIGHT ADJUSTMENT
Figure 9
An adjusting plate and thumb lever at each front
wheel provides cutting height adjustment. Each
adjusting plate has nine height positions. Height of
cut will be changed when the thumb lever is moved
from one position to another. Simply depress the
lever towards wheel and move wheel and lever
assembly to desired position. See Figure 9.
HANDLE HEIGHT ADJUSTMENT
(230 series mowers only)
Your mower is shipped with the handle in the higher
height position. To lower the handle height, proceed
as follows.
1. Remove the starter rope from the rope guide.
2. Remove the upper handle by removing the
hand knobs and carriage bolts. Lay the upper
handle out of the way, being careful not to bend
or kink the cables.

the handle brackets. Press outward on the legs
of the lower handle, and remove it from the
