Operating

Poor engine performance can result from improper break-in or incomplete break-in time. Break-in is the period of initial run time that seats the piston rings to the cylinder wall.

New engines need to be run hard, under varying loads for at least 5 hours and may not be completely broken-in until after 50 hours. Follow these guidelines:

· Run engine at full throttle during operation. Use partial throttle only for 30-60 seconds to warm a cold engine.

· Run engine under load by mowing, blowing snow, etc.

· Check oil and coolant (if equipped) levels often. Top off as necessary.

· Follow the break-in service intervals.

Engine may show these symptoms during break-in:

· Excess exhaust smoke at startup and during operation.

· High oil consumption.

· Low power/compression.

· Slight surging at full throttle when not under load.

· Fuel in the oil.

Daily Operating Checklist

o Test safety systems.

o Check tire pressure.

o Check fuel level.

o Check engine oil level.

o Check transmission oil level.

o Check coolant level on liquid cooled engine.

o Remove grass and debris from machine.

o Clean air intake screen.

o Check area below machine for leaks.

Avoid Damage to Plastic and Painted Surfaces

· Do not wipe plastic parts unless rinsed first.

· Insect repellent spray may damage plastic and painted surfaces. Do not spray insect repellent near machine.

· Be careful not to spill fuel on machine. Fuel may damage surface. Wipe up spilled fuel immediately.

Testing Safety Systems

TS220

c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Move the vehicle to an outside area before running the engine.

Do not run an engine in an enclosed area without adequate ventilation.

NOTE: Chains are available from your John Deere dealer.

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

2. Lay chains out flat with the cross chain hook ends facing downward.

3. Remove any twists and tangles from cross chain and rim chain.

4. Drive machine onto chains.

M73743

5. Drape chain over tire with the lever fastener on outside of tire and cross link hooks (A) facing upward and away from tire.

6. Adjust chain for straightness and an even amount of cross chain links on each side of tire.

7. Place the first cross chain (opposite the end with fastener and inside hook) under tire.

8. Pull the inside rim chain tight and hook the inside hook.

M73746

11. Tie excess rim chain links (G) back to the rim chain.

12. Drive forward on chains 9-12 m (30-40 ft.) and recheck for tightness. Adjust as necessary.

Mowing Tips

The following recommendations will produce the best lawn cut quality and appearance:

· Keep mower blades sharp. Dull blades will tear grass; tips of grass will then turn brown.

· Cutting grass too short may kill grass and let weeds grow easily. The suggested finished cut height range is 44-70 mm (1-3/4 to 2-3/4 in.).

· Adjust cutting height to remove only 1/3 of the grass at a time.

· Do not mow wet grass.

· Mow grass often. Short grass clippings will decay quickly.

· Mow with engine at full throttle.

· Adjust travel speed to match mowing conditions:

· Travel at slow speed when you mow thick, tall grass, make sharp turns or trim around objects.

· Travel at moderate speed when you mow thin grass.

· Use a different mowing pattern each time you mow. Overlap mowing paths 50-100 mm (2-4 in).

· Drive over ridges and through shallow ditches straight-on, not at an angle.

· A thick layer of mulched leave can prevent sunlight from getting to grass and smother it. Taller grass heights allow mulched leaves to dispense easier in lawn. Mulch leaves several times if needed.

· Use a thatcher in late spring or summer to pull up dead grass and aerate ground.
