3. Using a pair of needle-nose pliers or a
magnet remove the filter.
4. Replace the filter and drain plug (torque
to 115-135 in-lbs) and fill through the
expansion reservoir slowly until the
“FULL COLD” line. Allow the transmission
oil to move through the system and top
off as necessary.
5. Replace the cap and fully tighten.
Tractor Storage
If your tractor is not going to be operated
for an extended period of time (30 days to
approximately six months), the tractor should
be prepared for storage. Store the tractor in a
dry and protected location. If stored outside,
cover the tractor (including the tires) to protect
it from the elements. The procedures outlined
below should be performed whenever the
tractor is placed in storage.
1.
Change the engine oil and filter following
the instructions provided in the
Engine Operator’s Manual packed with
this manual.
WARNING
Never store the tractor with fuel in the tank indoors or
in poorly ventilated enclosures, where fuel fumes may
reach an open flame, spark, or pilot light as on a furnace,
water heater, clothes dryer, etc.
2. If storing the tractor for 30 days or more:
a. To prevent gum deposits from
forming inside the engine’s
carburetor and causing
possible malfunction of
the engine, the fuel system
must be either completely
emptied, or the gasoline must
be treated with a stabilizer to
prevent deterioration.
WARNING
Fuel left in the fuel tank deteriorates and will cause
serious starting problems.
b. Use a fuel stabilizer for storage
between 30 and 90 days:
• Read the product
manufacturer’s
instructions
and recommendations.
• Add to clean, fresh
gasoline the correct
amount of stabilizer
for the capacity
(approximately 3 gallons)
of the fuel system.
• Fill the fuel tank with
treated fuel and run the
engine for 2-3 minutes
to get stabilized fuel into
the carburetor.
c. Emptying the fuel system for
storage of more than 90 days:
• Prior to putting the tractor
in storage, monitor fuel
consumption with the
goal of running the fuel
tank empty.
• Run the engine until it
begins to stall. Use the
choke (if equipped)
to keep the engine
running until all fuel
in the carburetor has
been exhausted.
• Referring to the Engine
Operator’s Manual,
drain the fuel from the
carburetor bowl.
3. Clean the engine and the entire
tractor thoroughly.
4. Fully charge the battery, then disconnect
the negative cable at the battery to
prevent possible discharge. Recharge
the battery periodically when in storage.
Note:
Remove the battery if exposed
to prolonged periods of sub-freezing
temperatures. Store in a cool, dry location
where temperatures are above freezing.
5. Lubricate all lubrication points.
Note:
Using a pressure washer or garden
hose is not recommended for cleaning your
tractor. It may cause damage to electrical
components, spindles, pulleys, bearings or
the engine. The use of water will result in
shortened life and reduce serviceability.
Removing the Tractor from Storage
1. Check the engine oil.
2. Fully charge the battery and inflate the
tires to the recommended pressure.
3. Fill the fuel tank with clean, fresh gasoline.
4. Start the engine and allow to idle for
a few minutes to ensure engine is
operating properly.
5. Drive the tractor without a load to
make certain all the tractor systems are
functioning properly.
Adjustments
WARNING
Shut the engine off, remove the ignition key, and engage
the parking brake before making adjustments. Protect your
hands by using heavy gloves when handling the blades.
Deck Leveling
Note:
Check the tractor’s tire pressure before
performing any deck leveling adjustments. Refer
to Tires for information regarding tire pressure.
Always level the deck side-to-side before front
to rear.
Side-to-Side Leveling
1. Park the mower on a flat paved surface,
engage the parking brake, shut off the
engine, remove the key from the ignition
switch, disconnect the spark plug wires,
using the deck lift pedal position the
mowing deck into the 4” height of cut
position (the 4” height of cut position is
recommended in order for one to see and
obtain a measurement. Any height of cut
position is acceptable as long as a proper
measurement can be taken) and rotate
both outside blades so that they are
perpendicular with the tractor.
2. Measure the distance from the outside
of the left blade tip to the ground and
the distance from the outside of the
right blade tip to the ground. Both
measurements taken should be equal. If
they’re not, proceed to the next step.
3. Adjust the eyebolt (a) at the left front of
the deck so that the blade-to-ground
height at the right outside blade tip
matches that of the left outside blade
tip. This is done by loosening the
jam nuts (b) on the eyebolt (a) and
tightening the upper jam nut (b) to raise
the deck and loosening the jam nut (b)
to lower the deck. The right outer blade
tip height is fixed by the right, front
eyebolt (a) so you must adjust the left
outer tip to match it. See Figure 4-11.

4. Once the proper adjustment is made,
re-tighten the jam nuts (b).
Front-to-Back Leveling
1. Park the mower on a flat paved surface,
engage the parking brake, shut off the
engine, remove the key from the ignition
switch and disconnect the spark plug
wires. Using the deck lift pedal position
the mowing deck into the 4” height
of cut position (the 4” height of cut
position is recommended in order for
one to see and obtain a measurement.
Any height of cut position is acceptable
as long as a proper measurement can be
taken) and rotate both outside blades so
that they are parallel with the tractor.
2. Measure the blade-to-ground height at
the right rear blade tip. Again be sure
to measure the blade tip at the rear of
the right blade when aligned along the
mower centerline. The blade-to-ground
height at the rear of the blade tip should
be 1/8” to 1/4” higher than the front tip.
This is referred to as blade pitch. The
same height difference should be true
for the left blade, measured front and
back. The pitch should not exceed 1⁄16” if
cut height is below 1-1/2”.
3. Loosen the jam nuts (b) at the rear left
and right of the deck eyebolts (a). Refer
to Figure 4-11.
4. Start at the rear right to raise the rear of
the deck, tighten the upper jam nut (b)
to raise the deck or loosen the upper
jam nut (b) to lower the rear of the deck.
Refer to Figure 4-11.
5. Adjust the jam nut (b) at the rear left to
take the “slack” out of the threaded rod.
Refer to Figure 4-11.
6. Tighten both lower jam nuts (b) to secure
the deck adjustment. Refer to Figure 4-11.
7. The final adjustment would be to take the
“slack” out of the left rear linkage if the
rear of the deck was raised by adjusting
the jam nuts (b) on the eyebolt (a). Loosen
the jam nuts (b) and tighten the upper
jam nut (b) to remove “slack
”.
Refer to
Figure 4-11.
8. In many cases it will be necessary to
adjust deck height using both eyebolt (a)
adjustments and pitch adjustment to
achieve the correct blade-to-ground
heights. If you remember that the front
right blade tip adjustment is fixed
and you level to that height, adjusting
the decks will be simplified. Refer to
Figure 4-11.
