• Turn off the blades when not mowing. Before leaving the machine, turn off the
blades and stop the engine.
• Watch for traffic when operating near or crossing roadways.
• Do not operate the mower if the mower has been dropped or damaged
in any manner or if it vibrates excessively. Excessive vibration is an
indication of damage. Repair mower as necessary.
• Dress properly. Do not operate the mower when barefoot or
wearing open sandals. Wear only solid shoes with good traction when
mowing.
• Do not operate the machine while under the influence of alcohol or
drugs.
• Operate self-propelled machines up and down slopes. There is
significant risk of overturns when operating across slopes. Operate walk-
behind machines across slopes. There is a significant risk of slipping
under a walk-behind machine when operating up and down slopes. Do not
operate on slopes greater than 15 degrees.
• Never tamper with safety devices. Check their proper operation
regularly.
• Stop and inspect the equipment if you strike an object. Repair, if
necessary, before restarting.

OPERATING YOUR TRAIL MOWER
INTENDED USE
The 44” Trail Mower is designed to produce a quality finish cut on lawns, golf courses,
etc. It is not intended to clear brush or cut saplings. Your Trail Mower should be
towed behind an ATV, golf cart, lawn tractor, or other approved vehicle. It is not
designed for speeds exceeding 5 MPH. WARNING: To avoid serious injury,
operate your mower up and down the face of slopes, NEVER across the face. DO
NOT MOW SLOPES GREATER THAN 15 DEGREES! (See attached guide for
sighting slopes.)
ATTACHING TRAIL MOWER TO TOW VEHICLE
• Back vehicle up to desired towing position.
• Offset the Trail Mower to the side opposite the tow vehicle discharge (if any).
This prevents the tow vehicle from throwing grass into Trail Mower engine.
• If tow vehicle has a ball hitch, the ball must be removed before hitch can be
fastened.
• Attach hitch to the tow vehicle with hitch pin (H11). Make certain the hitch
pin goes completely through and is clipped to prevent accidental separation.
• Securely attach safety tether (6736) to tow vehicle and to the Trail Mower
toggle switch located on right side of the engine. The safety tether will stop the
Trail Mower engine either manually or if the two should become separated. It is
very important that the safety tether is securely attached to both the toggle
switch and to the tow vehicle. See Fig 3, pg 15.
The operation of any mower can produce foreign objects to be thrown into the
eyes, resulting in severe eye damage. Always wear certified safety glasses or
wide-vision safety goggles over spectacles before staring any cutting machine
and while operating such a machine.
The operation of any cutter produces sound waves that are damaging to the
human ear. Ear protection is recommended.
CAUTION!
Tragic accidents can occur if the operator is not alert to the presence of
children. Children are often attracted to the machine and the mowing
activity. Never assume that children will remain where you last saw
them.
TRANSPORTING MOWER
• Stop Trail Mower.
• Place Trail Mower deck in its highest position.
• When transporting without the use of a tow vehicle, remove spark plug
wire and place it where it cannot contact the spark plug.
6

• Set vehicle parking brake or chock wheels to prevent accidental rolling.
• Start engine properly.
• Slowly engage blade control.
• In a safe environment, i.e. no children, allow blades to rotate and engine to
idle for 5 minutes. This breaks in the belts and the engine.
• Stop mower properly.
ENGAGING BLADES
The Trail Mower will not start if the blade lever is in the “ENGAGED” position.
• Engage blades by rotating blade lever into the “ENGAGED” position.
• Rotate blade lever in opposite direction to disengage blade.
• The dual braking system is applied when the blades become disengaged. It is
designed to bring the blades to quick stop (approximately 7 seconds). Each
Trail Mower brake system has been tested and calibrated. For safety, the
consumer should not alter the braking system.
STARTING THE ENGINE
See engine manufacturer’s recommendations for the type and amount of oil and fuel
used. Trail Mowers equipped with an electric start engine will need a battery (sold
separately). Swisher recommends using a standard “12N12A” battery.
• Make sure the tow vehicle parking brake is set, mower is level, and blades are
disengaged. Engine must be level to accurately check and fill oil. Do not overfill.
• Check spark plug wire, oil, and fuel.
• Check all electrical connections for buildup or debris.
• Make sure toggle switch is not turned “OFF” and safety tether is attached.
• Set engine throttle to “RUN” position.
• Move the choke lever to the “ON” position (cold engine only).
• With feet clear of mower deck, turn key switch to the “START” position; release
when engine begins to run (12 volt models). Recoil models must use pull-rope.
Pull rope with a single fluid motion.
• Set engine throttle at maximum RPM.
• Allow engine to run a few moments before engaging blades.
BREAKING IN YOUR MOWER
CAUTION!
SHUT OFF MOWER ENGINE AND REMOVE SPARK PLUG WIRE FROM
SPARK PLUG BEFORE MAKING ANY ADJUSTMENTS TO THE MOWER.

IMPORTANT: This engine is not equipped with a spark arrester muffler. It is a violation of
California Public Resource Code Section 4442 to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land. Other states or federal areas may have similar laws.

• There is approximately 1 ½” to 4 ½” of height adjustment.
• Rotate height adjust crank handle in a clockwise direction to lower the mower
deck. A counter-clockwise direction is used to lift the mower deck.
• Graduated scales are for reference only, not the actual cutter height.
• Bring tow vehicle to a complete stop, shut off engine, and set parking brake.
• Disengage blades.
• Manually shut toggle switch and/or key switch to their “OFF” positions.
• Always remember to remove keys to avoid irresponsible usage (electric start
models only).
• Adjust the cutting height.
• Double check vehicle to mower attachment.
• Start mower engine and set throttle to “FAST” for best cutting performance.
• Slowly engage blade clutch lever.
• Carefully mount vehicle and start mowing at a slow travel speed.
• Swisher recommends if the tow vehicle is equipped with a mid-mount mower
to overlap the cut approximately 6”. This may vary depending on mowing
terrain, obstacles, and/or tow vehicle. Always keep SAFETY the first priority.
• If the tow vehicle is not equipped with a mid-mount mower, we still
recommend offsetting the mower so that the tow vehicle does not crush the
grass.
• Make adjustments while Trail Mower is not running.
• Remove hairpins NB127 from clevis pins 18842 so L-hitch 18829 can
be repositioned.
• Raise or lower hitch section to obtain proper front to back adjustment.
• Insert clevis pins in the desired hitch position and secure with hairpins.
MOWER HEIGHT ADJUSTMENT
• Make adjustments while Trail Mower is not running.
FRONT TO BACK ADJUSTMENT
For best cutting results, the mowing deck should be raised to ½” to ¾” higher in
the rear.
TOW HITCH OFFSET
This Trail Mower has been designed to operate offset from the center of the tow
vehicle or consecutively with another Trail Mower, providing additional cutting
width. When offsetting the mower do so to the side opposite the discharge of the tow
vehicle.

SUGGESTED MOWING PRACTICES
• Operate mower engine at full throttle to assure the best cutting performance and
maximum material discharge.
• Allow wet grass to dry. Wet grass will clump and collect under the mowing deck.
• Mowing should be started with tow vehicle in low gear and increased only as safe
mowing conditions permit. Mowing speed should not exceed 5 MPH.
• The average lawn should be cut to approximately 2.5” during the cool season and to
over 3” during the hot months.
• For a healthier lawn and better aesthetics, your lawn should be mowed often and
after moderate growth.
• When cutting high or dense grass areas go slowly. Some areas may need to be
mowed twice. The second cut should be at 90 degrees to the first, if possible.
•Mowing thick or high grass: Raise rear of deck to ½” to ¾” above front of the
deck. See “FRONT TO BACK ADJUSTMENT”. When mowing thick or high grass,
it is recommended to cut area twice. The first at a higher setting and the second at the
desired lawn height.
•Creating a manicured lawn: Never cut more than 1/3 of the grass height in one
cutting.
GENERAL TROUBLE SHOOTING
The mower is not cutting level.
• Check air pressure of all tires; make sure they are equal. See tires for
maximum inflation.
• Make certain blades are installed identically, without the engine running.
The engine will not start.
• Disengage blades, turn toggle switch to “OFF” position, check battery and all
other electrical connections, and inspect spark plug and wire.
• Contact engine manufacturer or qualified mechanic.
Engine runs poorly.
• See engine manual.
• Check the throttle adjuster.
• Replace fuel, clean fuel filter and fuel line.
• Check spark plug and gap.
Mower bounces excessively while towing.
• Decrease tire pressure.
• Tow at a slower speed.
IF PROBLEMS PERSIST HAVE A QUALIFIED MECHANIC SERVICE THE
MOWER. NEVER ATTEMPT TO MAKE AN ADJUSTMENT THAT YOU
ARE NOT SURE IS CORRECT. DOING SO CAN CAUSE OTHER
PROBLEMS.
