c. Emptying the fuel system for storage of more than 90 days:
• Prior to putting the mower 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 mower 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 mower. 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 Mower 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 mower without a load to make certain all the mower systems are
functioning properly.
ADJUSTMENTS
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 mower'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, 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 perpendicular with the mower.
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 are not, proceed to the next step.
PRODUCT CARE
WARNING
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 (Figure 46).
4. Once the proper adjustment is made, re-tighten the jam nuts (b) (Figure 46).
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 mower.
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)
(Figure 46).
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
(Figure 46).
5. Adjust the jam nut (b) at the rear left to take the "slack" out of the threaded rod
(Figure 46).
6. Tighten both lower jam nuts (b) to secure the deck adjustment (Figure 46).
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"
(Figure 46).
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 deck will be simplified (Figure 46).
