Winter Storage
At the end of the mowing season, or when it will not be in
use for more than 30 days, the Zero Turn Mower should
be readied for storage.
Fuel allowed to stand for long periods of time (30 days
or more) can leave sticky residues that can plug the car-
buretor and disrupt engine function.
Fuel stabilizers are an acceptable option as regards to
the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank and in the storage
container.
Always use the mixing ratios specified by the manufac-
turer of the stabilizer.
Run the engine for at least 10 minutes after adding the
stabilizer so that it reaches the carburetor. Do not empty
the fuel tank and the carburetor if you have added stabi-
lizer.
Never store an engine with fuel in
the tank indoors or in poorly venti-
lated spaces where fuel vapor can come in contact with
open flames, sparks, or a pilot light such as in a boiler,
hot water tank, clothes dryer, etc. Handle the fuel with
care. Gasoline Fumes are very flammable and can cause
serious personal injury and property damage. Drain the
fuel into an approved container outdoors and store far
away from open flame or sources of ignition. Never use
gasoline for cleaning. Use a degreaser and warm water
instead.
Preparing the Machine for storage:
1. Thoroughly clean the Zero Turn Mower, especially
under the Zero Turn Mower deck. Touch up damage to
the paint and spray a thin layer of oil on the underside of
the Zero Turn Mower deck to avoid corrosion.
2. Inspect the Zero Turn Mower for worn or damaged
parts and tighten any nuts or screws that may have be-
come loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer. Start the
engine and allow it to run until the carburetor is drained
of fuel or the stabilizer has reached the carburetor.
5. Remove the spark plug and pour about a tablespoon
of engine oil into the cylinder. Turn over the engine so
that the oil is evenly distributed and then re-install the
spark plugs.
6. Lubricate all grease fittings, joints, and axles.
7. Remove the battery. Clean, charge, and store the bat-
tery in a cool place, but protect it from direct cold or freez-
ing.
8. Store the Zero Turn Mower in a clean, dry place and
cover it for extra protection.
New Season Preparation
Before starting the mower following post season storage,
the following service is required:
Always check that fresh oil has
been added to Zero Turn
Mower. If oil is drained at season’s end and not re-
placed, engine damage will result.
1. Clean Zero Turn Mower, removing trash and dirt accu-
mulation.
2. Check engine oil and hydraulic oil levels.
3. Fill fuel tank with fresh fuel. Run Zero Turn Mower at
half speed for 5 minutes, checking operation of steering
control lever. Stop engine and check for oil leaks, loose
fittings.
4. Tighten any bolts that have loosened and make sure
all hair pins, cotter pins and clevis pins are in place.
5. Check that all safety shields are in place and secure
and review safety precautions listed in this manual.
6. Check Mower belt and drive belt for damage or severe
cracking and replace if needed.
7. Check Mower blades for sharpness and damage. Re-
place or sharpen if needed.
8. Check and inflate tires to 15 psi / 1 bar / 103 kPa.
9. Install fully charged battery and attach the battery ca-
bles.
10. Check Safety system startup. Refer to
Safety Sys-
tem
in the
Maintenance Section
.
11. Refer to engine manual for more information.
If Service Parts are required
after New Season Preparation
check is completed use only Genuine Bush Hog

Turn Mower performance, void warranty and pres-
ent a safety hazard
