Prepare for Assembly

· Remove machine from the shipping crate:

· Cut plastic tie straps fastening the rear drive wheels to the shipping crate.

· Cut tie bands fastening the rear of the machine to the shipping crate pedestal.

· Cut plastic tie straps fastening the front wheels to the shipping crate.

· Cut plastic tie straps fastening the rollers on the front of the deck to the shipping crate.

· Cut plastic tie straps fastening the motion control levers to the foot plate.

Install Rear Drive Wheels

c CAUTION: Avoid injury! Help prevent serious bodily injury from a falling vehicle. Use a safe lifting device when performing this assembly procedure.

1. Remove eight lug nuts from bag of parts.

2. Lift rear of machine with a safe lifting device.

3. Check drive wheel tire inflation pressures:

· Keep tires inflated to 69-97 kPa (10-14 psi).

MX10288

4. Attach one wheel to each hub (A) using four lug nuts, tighten until snug.

· Mount each wheel with the valve stem facing to the outside.

5. Lift front of machine with a safe lifting device

6. Remove shipping crate base from under machine.

7. Lower machine.

MX10287

· Tighten wheel nuts in numbered sequence shown for safe wheel installation. Tighten alternately until recommended torque value is reached.

· Tighten nuts to 100 N·m (75 lb-ft).

Check Tire Pressure

c CAUTION: Avoid injury! Explosive separation of a tire and rim parts can cause serious injury or death: · DO NOT attempt to mount a tire without the proper equipment and experience to perform the job. · Always maintain the correct tire pressure. DO NOT inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel. · When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. · Check tires for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.

1. Check tires for damage.

2. Check tire pressure with an accurate gauge.

3. Add air, if necessary:

Install Motion Control Levers

MX10293

1. Install each motion control lever (A) to the outside of the control arm (D) with two M10 flange screws (E) and two M10 hex flange lock nuts (B).

· Motion control lever tabs (C) should be directed to the rear of the mower.

· Position each motion control lever so the attaching hardware is installed in the center of the slotted tab holes.

· Tighten hardware.

2. Check motion control lever alignment.

MX10340

· Move both motion control levers forward.

· Check gap (F) between the levers. The recommended gap is 3-6 mm (1/8-1/4 in.).

NOTE: If the ends of the levers strike against each other while in the neutral position, move the levers outward to the neutral lock position and carefully bend them outward. Move them back to the neutral position and check for the recommended gap of 3-6 mm (1/8 - 1/4 in.).

· Check levers for equal alignment.

· If positions of the levers are unequal, loosen attaching hardware and slide both levers forward or rearward to desired position within tab slots until levers are aligned.

Connect Battery

c CAUTION: Avoid injury! Prevent Battery Explosions: · Keep sparks, lighted matches, and open flame away from the top of battery. Battery gas can explode. · Never check battery charge by placing a metal object across the posts. Use a volt-meter or hydrometer. · Do not charge a frozen battery; it may explode. Warm battery to 16 degrees C (60 degrees F).

MX10292

1. Raise seat frame (A) until support rod (B) locks.

MX10333

2. Connect positive (red) cable to battery.

· Install red terminal cover (D).

3. Connect negative (black) cable (C) to battery.

4. Secure rubber hold-down strap (E).

Install Seat

1. Move the motion control levers to the swing-out neutral lock position.

2. Remove protective covers from seat screws.

MX10289

3. Determine proper bolt pattern for seat type:

· Standard Seat (A)

· Deluxe Seat (B)

MX10292

4. Raise seat frame (C) until support rod (G) locks. Secure seat to frame with M8 lock nuts (D).

5. Connect harness (E) on seat to harness (F) on machine.

Check Engine Oil Level

MX10321

1. Remove oil dipstick (A). Wipe it clean.

2. Install dipstick in tube.

MX10285

3. Remove dipstick and check oil level. Oil level must be between "low" (B) and "high" (C) marks on dipstick.

4. Install dipstick.

Check Mower Deck Level

The mower deck is assembled and adjusted at the factory. After machine is completely assembled check the mower "Front to Rear" and "Side to Side" deck level.

Check Machine Safety Interlock System

Perform safety system check to make sure the electronic safety interlock circuit is functioning properly.
