1. Select desired cutting height before starting engine.
2. Be sure drive lever or blade lever are not engaged.
3. Choke if necessary.
4. Pull back on starter rope slowly until resistance is felt. Then pull cord rapidly to start. Repeat if necessary.
Do not operate if excessive vibration occurs. If excessive vibration occurs, shut engine off immediately and check for
damaged or worn blade, loose blade bolt, loose engine or lodged foreign objects. Note: See maintenance section for
proper blade bolt torque specifications.
Using two people to lift machine is recommended. Lift holding the handle and the caster arm at the front of
deck. Secure in place during transport.
Never lift the machine while the engine is running. ENGINE MUST BE OFF while handling, lifting, or
transporting the unit on or off the vehicle.
Never store engine indoors or in enclosed poorly vent
an open flame, spark or pilot light, such as a furnace, water heater, clothes dryer or other gas appliance.
If engine is to be unused for 30 days or more, prepare as follows:
Be sure engine is cool. Do not smoke. Remove all gasoline from carburetor and fuel tank to prevent gum
deposits from forming on these parts and causing possible malfunction of engine. Drain fuel outdoors, into an
approved container, away from open flame. Run engine until fuel tank is empty and engine runs out of gasoline.
NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or storage container. Always follow mix ratio found on stabilizer container.
Run engine at least 10 min. after adding stabilizer to allow it to reach the carburetor.
CAUTION: Wheels must be chocked or blocked when unit is parked on a slope.

when work is not being performed.
CUTTING HEIGHT ADJUSTMENT
back, remove lynch pin, remove all spacers then set if off to the side,
remainder of spacers if any, then reinsert lynch pin (see figure right).
Note
that all cutting heights will be from the lowest cutting edge with standard blades
CAUTION: Shut off the blades when crossing gravel drives, walks
objects might be a hazard.
CLEARING A CLOGGED CUTTING DECK: Turn engine off and wait for blade to stop completely. Disconnect
spark plug wire and place the unit in gear to prevent the unit from rolling.
Wearing durable gloves, remove clog. Danger, the clog may contain sharp materials. Reconnect spark plug
CAUTION: Use extreme care when operating the blades. Inspect the work area for foreign objects that could
cause damage to the unit or injure the operator if struck by the blade. Never operate the blades with bystanders in
the work area.
GENERAL OPERATION: To engage the blades, depress the operator’s left hand control lever against operator’s
handle. The blade is disengaged by releasing this lever. (See Fig. 16-5 next page) To engage the wheel drive lift the
operator’s right hand control lever against operator’s handle. The drive is disengaged by releasing this lever.(See
Fig. 16-6 next page) Ground speed can be varied by shifting gears as described on page 11. To begin cutting,
the material to be cut.
NOTE: Do not engage blades during transport between work sites. The blade should remain disengaged at all times
The best performance is achieved when cutting in dry conditions. If the deck becomes choked with grass or debris
during operation, back unit off of debris allowing machine to clear itself and continue cutting, or shut the unit off and
clear the clog by hand (See above). A drop in engine RPM or a noticeable change in engine sound is usually a good
indicator of a clogged discharge or other interference.
Under most conditions cutting should be done in second or third gear. The quality of the cut produced is directly
related to the unit's ground speed during cutting. If the quality of the cut is not satisfactory (i.e. material left standing)
you should shift into a lower gear during cutting.
CAUTION: DO NOT make cutting height adjustment when
engine is running.
Cutting height can be adjusted from 1.5" to 3.5" by placing spacers
above or below caster spindles. For easiest adjustment change the
height on one side at a time. To change cutting height, tilt the unit
remove caster rig, add or subtract spacers, reinstall caster rig, place
Repeat this step on other side. For finer adjustment relocate the
bolts located on the deck brackets to change the angle of the deck.
See the chart below for the corresponding positions and cutting
heights
NOTE: Be sure that the spacers are even on both casters. Running
the deck out of level will result in poor cut quality.

CABLE ADJUSTMENTS
Transaxle Drive Control Cable Adjustment
When the transaxle drive belt slips, the drive control cable needs to be adjusted or the
belt needs to be replaced with a new belt.
Cable Adjustment:
2. Using a ½ “ open end wrench, turn the inside adjusting nut counter-clockwise and
back it off 1/8", then tighten the outboard adjusting nut against the support bracket (see
figure 17-2).
3. Check for proper operation. If the operation is not correct, repeat step 2.
4. Replace the access door.
The drive control cable adjustment should be the minimum amount required so the belt
does not slip when the drive is engaged.
Blade Drive Control Cable Adjustment
When the blade drive control lever is depressed, the blades should turn and the blade
drive belt should not slip. When the cable is properly adjusted the tension spring on the
end of the control cable will open slightly (only enough for a piece of paper to slip
between the coils). Cable Adjustment:
1. Remove the belt cover and observe the tension spring on the end of the cable that
attaches to the idler when the blade drive lever is depressed. The spring should just
break open.
2. If adjustment is required, using a ½” open end wrench, turn the inboard adjustment
nut counter-clockwise and back it off 1/8". Then tighten the outboard adjustment nut
against the cable support bracket (Item 49).
3. Check the spring tension with the blade drive lever depressed.
4. Readjust the control cable as needed for proper tension.
5. Replace the deck belt cover.
Note: Too much tension will shorten belt and bearing life and too little tension will allow
the belt to slip.
