On your machine safety labels, the words DANGER,

ASSEMBLY

• Always shut off fuel when storing or transporting the machine, if the machine has a fuel shutoff.
• Do not store the machine near an open flame or source of ignition, such as a water heater or furnace.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary
• Never remove the fuel tank cap or add fuel with the engine running. Allow the engine to cool before refueling.
• Never add fuel to or drain fuel from the machine indoors. Move the machine outdoors and provide adequate ventilation.
• Clean up spilled fuel immediately. If fuel is spilled on clothing, change clothing immediately. If fuel is spilled near the machine, do not attempt to start the engine but move the machine away from the area of spillage. Avoid creating any source of ignition until fuel vapors have dissipated.
• Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliance.
• Prevent fire and explosion caused by static electric discharge. Static electric discharge can ignite fuel vapors in an ungrounded fuel container.
• Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before fueling.
• Remove fuel-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a fuel dispenser nozzle.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock open device.
• Never overfill the fuel tank. Replace the fuel tank cap and tighten it securely.
• Replace all fuel container caps securely after use.
• For gasoline engines, do not use gas with methanol. Methanol is harmful to your health and to the environment.
• 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.

Checking Wheel Hardware

• A serious accident could occur causing serious injury if wheel hardware is not tight.
• Check wheel hardware tightness often during the first 100 hours of operation.
• Wheel hardware must be tightened to the specified torque using the proper procedure anytime it is loosened

Handling Waste Products and Chemicals

Waste products, such as used oil, fuel, coolant, brake fluid, and batteries, can harm the environment and people:

• Do not use beverage containers for waste fluids – someone may drink from them.
• See your local Recycling Center or authorized dealer to learn how to recycle or get rid of waste products.
• A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques. The seller of the chemical products used with your machine is responsible for providing the MSDS for that product.

Charge and Connect Battery

1. Remove and discard the tie strap from the positive (+) battery terminal.
2. Remove and discard the black protective cap from the negative (–) battery terminal.
3. Charge the battery.
   • The battery is fully charged at 12.6 volts.
4. Connect positive (+) battery cable (A) to the battery.
5. Connect negative (–) battery cable (B).

Operating

Daily Operating Checklist

• Test safety systems.
• Check tire pressure.
• Check fuel level.
• Check engine oil level.
• Remove grass and debris from the engine compartment and muffler area, and on top of the mower deck, before and after operating the machine.
• Clean air intake screen.
• Check the area below the machine for leaks.

Adjusting Seat

1. Sit in your seat.
2. Lift on the seat adjustment lever (A) on the right side of the seat.
3. Lean forward and slide the seat forward or rearward to the desired position. Do not lean back on top of seat to push rearward.
4. Release the seat adjustment lever to lock in position.

Lumbar Seat Adjustment (LA165, LA175)

• Turn lumbar seat adjustment dials (B) on either side of the seat to adjust the firmness of the seat.

Adjusting Cutting Height

Cutting height can be adjusted from approximately 25 – 100 mm (1 – 4 in.) in 6.4 mm (1/4 in.) increments. When the mower deck is in the transport position, the cutting height is approximately 100 mm (4 in.). Detents allow the adjustment lever to be positioned at each indicated mower setting, as well as the mid-point between each set.

1. Put the attachment lift lever into the slot adjacent to the desired cutting height.
2. Adjust mower deck wheels.

Transporting or Getting On and Off Machine

• Pull the attachment lift lever back to the transport position or 100 mm
  (4 in.) cutting height.

Checking Mower Deck Level

NOTE: Mower deck wheels should not contact the ground when leveling the mower deck.

1. Park the machine safely. (See Parking Safely in the SAFETY section.)
2. Inflate tires to the correct pressure.
3. Move the mower lift handle to the preferred cutting height.
4. Measure the mower deck level (side-to-side).Picture Note: A convenient leveling gauge (A) (AM130907) is available from your dealer.
   • a.Position mower blades as follows and measure from each outside blade tip (B) to the level surface.
   • b.Turn left blade (C) as shown. Hold the drive belt and turn the right blade (D) as shown. Take measurements for both blades. The difference between blade measurements must not be more than 3 mm (1/8 in.).
   • c.Adjust the mower deck level, if necessary.
5. Measure mower level (front-to-rear).
   • a.Turn the right blade (E) so the blade tip points straight forward.
   • b.Measure from blade tip to the surface. Take measurement for both blades. The front blade tip must be 3–6 mm (1/8 -1/4 in.) lower than rear blade tip.
   • c.Adjust the mower deck level if necessary.

Adjusting Mower Deck Level

NOTE: Mower deck wheels should not contact the ground when leveling the mower deck.

Method One

1. Make sure the machine is on a flat, level surface.
2. Check that tires are inflated to correct tire pressure. Tire pressure is marked on the side of the tire.Picture Note: 107 cm (42 in.) mower deck shown
3. Place three short 51 mm (2 in.) blocks of wood under the edges (A) of the mower deck.
4. Lower the mower deck to the 65 mm (2.5 in.) cutting height position.
5. Check that the mower deck is level and lightly touching each of the three wooden blocks.
   • If the rear of the mower deck is not touching the rear blocks, or is sitting heavily on the blocks, adjust the rear lift links by turning the leveling nut (B) on each lift link. The blocks should be able to easily slide in and out beneath the mower deck when the mower deck is correctly adjusted.Picture Note: 107 cm (42 in.) mower deck shown
   • If the front of the mower deck is not lightly touching the front block, adjust the front draft arm by turning the nut (C).
6. Raise the cutting height to the next highest position and remove the three wooden blocks.
7. Turn the nut (C) on the front draft arm counterclockwise for 1-2 full turns so that the front of the deck is 3-6 mm (1/8-1/4 in.) lower than the rear. This adjustment prevents “double cutting,” which wastes horsepower and causes brown grass tips.

Method Two

NOTE: An optional mower deck leveling gauge (AM130907) is available from your John Deere dealer. It allows for precision mower deck leveling by measuring the mower deck level at the blade tips.

1. Make sure the machine is on a flat, level surface.
2. Check that tires are inflated to correct tire pressure. Tire pressure is marked on the side of the tire.
3. Lower the mower deck to the 50 mm (2 in.) cutting height position.
4. With a tape measure or ruler, measure the left rear and right rear edge of the mower deck at points (A). If the two measurements are not equal, turn the leveling nut (B) on each rear lift link to adjust. Repeat the procedure until the rear corners of the mower deck are level.
5. Measure the front edge of the mower deck directly below the front draft arm hanger at point (A).
   • If necessary, turn the front draft arm nut (C) counterclockwise so the front edge of the mower deck is 3-6 mm (1/8-1/4 in.) lower than the rear corners of the mower deck.

Adjusting Mower Deck Wheels

1. Park the machine safely. (See Parking Safely in the SAFETY section.)
2. Inflate tires to the correct pressure.
3. Lower the mower deck to the desired mowing position.
   NOTE: Bottom of wheels should be approximately 3-13 mm (1/8-1/2 in.) from the ground.
4. Check each mower wheel position. Remove nut (A) and bolt (B), and move the mower wheel to the proper hole.
5. Install bolts and nuts to lock wheels in position. Tighten nuts to 34 N•m (25 lb-ft).

Testing Safety Systems

The safety systems installed on your machine should be checked before each machine use. Be sure you have read the machine operator manual and are completely familiar with the operation of the machine before performing these safety system checks.
