MAINTENANCE

DRIVE CHAIN ADJUSTMENT (Cont’d)

4. Replace the access cover and bolts.

NOTE: Failure to adjust tension will result in premature failure and could void your warranty.

ROTOR TOOTH WEAR

Before performing maintenance as outlined below be sure to:

1.Lower tiller to ground.

2.Turn off tractor.

If tiller must be raised off the ground, block securely.STANDARD TEETH

Rotor tooth length is critical to the efficient operation of the tiller. Length of the tooth should be no less than 1/2 inch. To keep your tiller performing effectively, we recommend that replacement teeth (Part no. 200-337-002)be welded onto the front of the original teeth when tooth length approaches the 1/2 inch minimum length. (See Figure 34.)

CARBIDE TEETH

Carbide teeth offer dramatically longer life. Due to tooth spacing, and rotor tubing material, carbide teeth cannot be welded onto an existing rotor. A new rotor with carbide teeth can be ordered for your tiller. Check with your authorized dealer for specific pricing. (See Figure 35.)

When welding rotor teeth, welder ground clamp must beattached to rotor to prevent current from flowing through bearings.
BEFORE EACH USE

1.Check tiller daily for loose, bent, broken, or missing parts.

2.Observe tiller’s general condition, noting points that may need attention.

3.Check rotor to be sure no foreign objects such as wire or weeds are wrapped around them.

4.Make certain drive line shields are in place and in good condition.

5.During operation, listen for abnormal sounds which might indicate loose parts, damaged bearings or other damage. Correct any problem immediately.

AFTER EACH USE

1.Clean all debris from tiller especially on the rotor.

2.To prevent rusting, touch up any spots where paint may have worn off.

3.Store in a clean, dry place.
