Operating - Mower


Adjusting Cutting Height

1. Stop machine on level surface, PTO off, park brake locked.

2. Raise all mower decks. Engage left and right side deck transport locks. Stop engine.

3. Check tire pressures on all machine tires, and deck caster wheels.

• Machine front tires: 207 kPa (30 psi)

• Machine rear tires: 193 kPa (28 psi)

• Mower deck caster wheels: 275 kPa (40 psi)

Adjusting Front Deck Cutting Height


MX3718

1. Remove retainer ring (A) from deck hanger pin (B) on left and right side of front deck.


MX0459

2. Using the figure above, or decal mounted on front deck, place deck hangers into holes that match desired cutting height.

3. Install retainer rings into hanger pins.

4. Adjust caster wheels on front deck to match cutting height selected on hanger.

Adjusting Caster Wheels Cutting Height

NOTE: This adjustment is for all caster wheels on front and side mower decks.

1. Raise mower decks.


MX0462

2. Support the caster wheel and bracket (A) with one hand, while removing quick-lock pin (B) and spacer guard (C).

3. Remove the spacers (D) from the top of the caster pivot shaft.

4. Lower the caster and pivot shaft out of the caster support bracket (E).


MX0459

5. Use the figures above, or decal mounted on front mower deck to select the number of spacers needed to set caster wheel to desired height.


MX0460

6. Flip caster support brackets over to adjust blades to higher than 102 mm (4 in.) cutting height.


MX0463

• To flip the caster support brackets (E), remove two cap screws, nuts, and bushings (F), holding support bracket to mower deck arm. Remove bracket from arm, flip over bracket, and install back into arm.

7. Install cap screws and nuts, but do not tighten nuts at this time.

8. Install the proper number of spacers onto the bottom of the caster shaft.

9. Install the caster wheel and bracket up though the caster support bracket.

10. Install remaining spacers onto the top of the caster shaft.

NOTE: When adjusting side decks to 25 mm (1 in.) height of cut, do not install spacer guard on inside caster wheel pivot. Spacer guard may contact engine cover when side deck is raised.

11. Install the spacer guard with open end facing forward (as shown).

12. Install quick-lock pin into caster shaft and hole in spacer guard. Snap retainer loop over caster shaft.

13. If cutting height was adjusted above 102 mm (4 in.), perform the follow steps:

a. Lower mower deck to ground.

b. Turn caster wheels so they are trailing to the rear (as would happen during normal forward travel).

c. Tighten caster support bracket hardware.

Checking Mower Deck Level

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Lower all mower decks completely to ground.

3. Check tire pressures on all machine tires, and deck caster wheels.

• Machine front tires: 207 kPa (30 psi)

• Machine rear tires: 193 kPa (28 psi)

• Mower deck caster wheels: 275 kPa (40 psi)

4. Set the mower decks at the desired cutting height.

5. Check that the front mower deck caster wheels and rear hangers are all set to the same height.

c CAUTION: Avoid injury! Rotating blades are dangerous. Before adjusting or servicing mower:

• Disconnect spark plug wire(s) or battery negative (-) cable to prevent engine from starting accidentally.

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

6. Check that all caster wheels are trailing towards the rear, as they would be during normal forward travel.

7. Turn the blades until parallel to the front axle.


MIF

Picture Note: A convenient leveling gauge (A) is available from your John Deere dealer that will slip under the lip of the deck and measure blade height.

8. Measure distance from tip of outside blade to the ground. Repeat for blade on other side of deck. Mower blades should be level on both sides of deck.

9. Turn outer mower blades to face front-to-rear.

10. Measure height of front and rear of outer blade to ground. Repeat for other side.

Results:

• The blade cutting heights should be level side-to-side.

• The rear tips of the blades should be 6 mm (0.25 in.) higher than the front blade tips.

Adjusting Mower Deck Level

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Lower all mower decks completely to ground.

3. Check tire pressures on all machine tires, and deck caster wheels.

• Machine front tires: 207 kPa (30 psi)

• Machine rear tires: 193 kPa (28 psi)

• Mower deck caster wheels: 275 kPa (40 psi)

4. Set the mower decks at the desired cutting height.

5. Turn all caster wheels so they are trailing to the rear (as would happen during normal forward travel).

Adjusting Front Mower Deck Level


MX3718

1. Loosen locknut (A) on deck hanger (B).

2. Remove retainer ring (C) on hanger pin (D).

3. Turn rear hanger up or down to adjust deck height until blades are level side-to-side and front-to-rear.

4. Insert hanger pin (D) back into proper height adjuster hole, and secure with retainer ring.

5. Tighten locknut (A).

NOTE: It may be necessary to reduce caster wheel air pressure on one side only to help level mower deck.

Adjusting Side Mower Deck Level

The side mower deck level can be adjusted by lowering the air pressure in the two caster wheels on the side which is high. Do not exceed recommended air pressure in tires.

Engaging Blades

c CAUTION: Avoid injury! Clear mowing area of all bystanders when operating this machine. Thrown objects could cause serious injury or death.

Keep hands and feet away from blades and discharge opening.

Do not mow in reverse unless absolutely necessary.

NOTE: Operate engine at full throttle while mowing.

1. Start engine and warm up.

2. Move the speed range lever to the low speed position.

3. Unlock the park brake.

4. Lower the mower decks to ground.

5. Move throttle forward to full throttle position.

6. Pull up on PTO switch.

• Blades should start.

• If one side deck is not lowered, the blades for that deck will not start up until deck is lowered.

• If front deck is not lowered, none of the blades will start up.

7. Raise decks to disengage blades:

• If a side deck is raised while mowing, the blades for that deck will stop. Blades will start up again once the deck is lowered.

• If the front deck is raised while mowing, all blades on all decks will stop. Once front deck is lowered, the PTO switch will have to be cycled on-off-on to restart blades.

• Move the PTO switch to the off position to stop all blades.
