Operating Mower Deck
Check Ground Conditions
ˇ Clear mowing area of objects that might be thrown. Keep people and pets out of mowing area.
ˇ Study mowing area. Set up safe mowing pattern. Do not mow under conditions where traction or stability is doubtful.
ˇ First, test drive area with PTO switch DISENGAGED and mower lowered. Slow down when you travel over rough ground.
Avoid Injury From Contacting Blades
Before you dismount to unplug or adjust mower:
ˇ DISENGAGE PTO switch to stop mower blades.
ˇ Wait for mower blades to STOP.
ˇ Keep hands, feet and clothing away from mower deck when engine is running.
ˇ DISENGAGE PTO switch to stop mower blades when you are not using mower.
Adjusting Cutting Height And Gauge Wheel
CAUTION: Avoid injury! Before you adjust the mower, STOP the engine. LOCK the park brake.

NOTE: The pointer (A) does not show the cutting height on the decal (B). The numbers 1-4 are for reference only.
1. Turn the crank (C) to put the mower at the desired cutting height-from 25-100 mm (1-4 in.). One turn of the crank will raise or lower the mower approximately 6 mm (1/4 in.). Leave the crank at the bottom of a turn.
2. Cut a short strip of grass. For best results, measure the height of the grass at several places in the strip.
NOTE: When the mower is set at the desired cutting height, note the pointer number on the decal. Use this number as a reference to set the cutting height in the future.
3. Remove the ring (D) and drilled pin (E) from the wheel arm.
ˇ For normal operation: Adjust the wheel to 6 mm (1/4 in.) above the ground.
ˇ For rough or uneven ground: If scalping is a problem, try running the wheel on the ground.
5. Install the drilled pin and the ring.
Checking The Mower Deck Side-To-Side Level
1. Park the Front Mower safely.
ˇ Front Mower drive tires: 60 kPa (8 psi)
ˇ Front Mower rear tires: 100 kPa (15 psi)
ˇ Mower Deck Caster Wheel tires: 310 kPa (45 psi)
3. Set the mower at the desired cutting height.
4. For 60 Inch mower deck, check that front caster wheel adjuster, and rear hanger adjustment are all set to the same adjustment height. (See "Adjusting Mower Deck Cutting Height" in this section.)
|
CAUTION: Avoid injury! The blades may have sharp edges. Wear heavy gloves or use a rag to protect your hands.
|
5. Turn the blades parallel to the front mower's axle.
NOTE: Use a short ruler or leveling gauge (B) for measuring.
6. Lift the mower chute. Measure from the right blade tip to the floor (A).
7. Measure from the left blade tip to the floor.
8. Dimension (A) on both blades must not differ by more than 3mm (1/8 in.). If the difference is greater, adjust the level.
Adjusting Mower Deck Side-to-Side Level
1. Raise and block one side of the mower - about 150 mm (6 in.).
3. Remove the wheel from the mower.
4. Put the top washer(s) (B) in the bottom position (C) to raise one side of the mower, OR put the bottom washer(s) in the top position to lower the mower. Keep the thin thrust washer between washer(s) (C) and the bottom bushing.
Checking Mower Deck Front-To-Rear Level
1. Park the Front Mower safely.
ˇ Front Mower drive tires: 60 kPa (8 psi)
ˇ Front Mower rear tires: 100 kPa (15 psi)
ˇ Mower Deck caster tires: 310 kPa (45 psi)
3. Check that front caster wheel adjuster, and rear deck hanger adjustment are all set to the same adjustment height. (See "Adjusting Cutting Height" in this section.)
|
CAUTION: Avoid injury! The blades have sharp edges. Wear heavy gloves or use a rag to protect your hands.
|
4. Lift discharge chute. Rotate the right blade by hand until it points front-to-rear.
5. Using a short ruler or blade leveling guide (A), measure cutting height from the bottom of the front blade cutting edge to the ground.
6. Turn the right blade 180 degrees. Measure cutting height from the bottom of the same cutting edge as used in step 5, (now pointing to rear).
7. Dimension (B) should be 3-6 mm (1/8-1/4 in.) greater with blade pointed rearward than when pointed forward. (Blade higher in rear).
Adjusting Mower Level Front-To-Rear
NOTE: Make adjustment to both sides of deck as needed.
2. Turn the turnbuckle (B) to raise or lower the rear of the mower.
