Mower Deck Removal and Installation

The mower deck has been installed at the factory. See your dealer for mower deck removal and installation.

Deck Leveling Adjustment

Determining if the Deck Leveling Needs to be Adjusted

1. Park the unit on a flat, level surface. Disengage the PTO, engage the parking brake, turn the ignition switch to OFF, and remove the ignition key.

2. Lock the deck lift pedal in the TRANSPORT position.
   Place the cutting height adjustment pin in the 4″ position and lower the deck lift pedal until the deck lift arm contacts the cutting height adjustment pin.

3. Verify that the tires are inflated to the correct pressure:
   • Front – 22 psi (1,72 bar)
   • Rear – 12 psi (0,83 bar)

4. Verify that the mower blades are flat, and not bent or broken. A bent or broken blade must be replaced.

WARNING
Avoid Injury! Mower blades are sharp.
Always wear gloves when handling blades or working near blades.
5. See Figure 1. Position the outside mower blades so they face front-to- back.

6. Measure (A, Figure 1) the front tip (B) of the blade from the cutting edge to the ground.
7. Measure the rear tip (C) of the blade from the cutting edge to the ground.
8. Repeat the process on the other side of the machine.
• The front measurements should equal 4″ (10,2 cm).
• The rear measurements should equal 4-1/4″ (10,8 cm).

If the measurements do not equal the measurements as listed above, adjust the deck leveling.

Deck Leveling Adjustment

1. Place the deck height adjustment pin in the 4″ (10,2 cm) position.
2. Place 2 X 4 blocks under each corner of the mower deck with the 3-1/2″ sides being vertical. Place a 1/4″ (0,64 cm) thick spacer on top of the rear blocks.
3. Loosen the nuts (A, Figure 2) and allow the front of the deck to rest on the 2 X 4’s. Slide the chains in the slots until the chains are tight and tighten the nuts.

4. Loosen the nuts (B, Figure 2) and allow the rear of the deck to rest on the 2 X 4’s and 1/4″ spacers. Slide the chains in the slots until the chains are tight and tighten the nuts.
5. Repeat the process for the other side of the unit.
6. Remove all blocks and spacers from under the mower deck.
7. Perform the Determining if the Deck Leveling Needs to Be Adjusted procedure to verify that the deck has been leveled correctly.

Deck Lift Assist Spring

Models are equipped with a deck lift assist spring (A, Figure
3) that assists the operator in raising the mower deck with the deck lift pedal. The deck lift assist spring is factory set to provide optimal lifting performance.

Although it is fastened with a multi-position anchor, this is not an adjustment point.

NOTICE Do NOT attempt to adjust the spring length or lifting performance will be compromised.

Mower Deck Drive Belt Replacement

NOTICE To avoid damaging belt, do not pry over pulleys

1. Park the mower on a flat, level surface, such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the ignition, and remove the key.
2. Lift the deck to the TRANSPORT position. Remove the mower deck guards and floor pan to gain access to the mower deck drive belt.

WARNING
Use extreme caution when rotating the idler arm with the breaker bar, due to the increased tension in the spring as the idler arm is being rotated. Injury may result if the breaker bar is prematurely released while the spring is under tension.

3. Using a 1/2″ breaker bar, place the square end in the square hole located in the idler arm (A, Figures 4, 5 & 6). Carefully rotate the breaker bar clockwise, which will relieve the tension on the belt exerted from the idler arm.

4. Slide the drive belt (B) over the edge of the rear stationary idler pulley (C). Carefully release the tension on the breaker bar.
5. Remove the old belt and replace with a new one. Make sure that the V-side of the belt runs in the spindle pulley (D) grooves.
6. Install the drive belt on the PTO pulley, the spindle pulleys (D), the front stationary idler pulley(s) (E), and the adjustable idler pulley (F). Carefully rotate the breaker bar clockwise and install the belt on the rear stationary idler pulley (C).

7. Carefully release the tension on the breaker bar.

Check / Adjust the Mower Deck Drive
Belt Tensioning Spring

1. Set the mower deck to its middle cutting position.
2. Use the Mower Deck Drive Belt Tensioning Spring Setting chart to determine the correct spring setting for your unit.
3. Measure the distance (A, Figures 7, 8, and 9) between the threaded end of the eye-bolt to the next wall. The measurement should equal the measurement as indicated in the chart. If not, continue with step #4.

4. Loosen the jam nut (C) on the eyebolt (D).
5. Turn the adjustment nut (E) until the measurement as indicated in the chart is achieved.
6. Tighten the jam nut.
7. Install the mower deck guards and the floor pan.
8. Run the mower under no-load condition for about five (5) minutes to break in the new belt.

Servicing the Mower Blades

Removing the Mower Blades

CAUTION
Laceration hazard
Mower blades are sharp.

Always wear gloves when handling, or working near, mower blades.

1. Use a block of wood to prevent the mower blade from turning as shown in Figure 10.

2. Using a wrench, remove the bolt securing the blade to the spindle.

Inspecting the Mower Blades

DANGER

Thrown objects hazard
Avoid injury: a worn or damaged mower blade can break and a piece of the blade could be thrown into the operator’s area or bystander’s area resulting in serious personal injury or death.

• Inspect the mower blade every 25 hours or at least once per year.
• If the mower blade hits a solid object, stop the engine immediately and inspect the mower blades.
• Never weld or straighten bent mower blades.

1. Remove the mower blade from the unit. See Removing the Mower Blades.
2. Inspect the mower blade (Figures 11 and 12). Discard the mower blade if it has any of the following conditions:
   • More than .5″ (12,7 mm) of the mower blade metal has been removed from previous sharpening or wear (A, Figure 11)
   • The air lifts are excessively eroded (A, Figure 12) and the notch (B) is .25″ (6,35 mm) deep or greater.
   • The mower blade is broken or bent.

3. If the cutting edges are not sharp or have nicks, sharpen the blades. See Sharpening the Mower Blades.

Sharpening the Mower Blades

WARNING

Thrown objects and fire hazard

Grinding mower blades throws sparks and fine metal particles that are capable of igniting gasoline and gasoline vapors, and that can injure unprotected eyes.

Be sure all flammable materials are cleared from the area where grinding will occur.

Always wear safety glasses or goggles when grinding mower blades.

1. Sharpen mower blades with a grinder, hand file, or electric blade sharpener.
2. Sharpen the blade by removing an equal amount of material from the cutting edge of each end of the blade.
3. Keep the original bevel (A, Figure 13) when grinding. DO
   NOT change the mower blade bevel.

4. The mower blade should have a maximum of 1/64″ (0,40 mm) cutting edge (B) or less.

Balancing the Mower Blades

CAUTION
Thrown objects hazard

An unbalanced mower blade can create excessive vibration and damage the unit, or cause mower blade failure resulting in thrown debris.

Be sure blade is balanced before installing.

1. Clean the mower blade to remove any dried grass or other debris.
2. Clamp a nail in a bench vise, hang the mower blade on the nail, and position the blade in a level horizontal position as shown in Figure 14.

3. Check the balance of the mower blade. If either end of the mower blade moves downward is heavier than the other. Sharpen the heavy end until balance is achieved. See Sharpening the Mower Blades for sharpening instructions.
4. Repeat the process until the mower blade remains in the horizontal, level position.

Installing the Mower Blades

1. Install each mower blade with the air lifts (C, Figure 15) pointing up towards the mower deck as shown in Figure 15 and secure with the mower blade mounting bolt (A) and flat washer (B).

2. Wedge a wooden block (D) between the mower blade and the mower deck housing to keep the mower blade from turning and torque the blade mounting bolt to 120 ft.lbs (163 Nm).

Lubrication

Lubricate the unit at the locations shown in Figure 16 as well as the following lubrication points.
