Belt Replacement

If the drive belt needs to be replaced, see your local authorized dealer or refer to the Replacement Parts Section for ordering information. Use only a factory-authorized belt as an “over- the- counter” belt may not perform satisfactorily. The procedure requires average mechanical ability and commonly available tools.

Tines

The bolo tines will wear with use and should be inspected at the beginning of each tilling season and after every 30 operating hours. The tines can be replaced either individually or as a complete set. See the Replacement Parts Section for tine identification and part numbers.

Tine Inspection

With use, the tines will become shorter, narrower and pointed. Badly worn tines will result in a loss of tilling depth, and reduced effectiveness when chopping up and turning under organic matter.

Removing/Installing a Tine Assembly:

1.A tine assembly consists of eight tines mounted on a tine holder.

2.If removing both tine assemblies, mark them “left” and “right” before removal. Remove the screw and locknut that secure the tine assembly to the tine shaft. If necessary, use a rubber mallet to tap the tine assembly outward off the shaft.

3.Before reinstalling the tine assembly, inspect the tine shaft for rust, rough spots or burrs. Lightly file or sand, as needed. Apply a thin coat of grease to the shaft.

4.Install each tine assembly so that the cutting (sharp) edge of the tines will enter the soil first when the tiller moves forward. Secure the tine assembly to the tine shaft using the screw and locknut.

Change Transmission Gear Oil

NOTE: The transmission gear oil does not need to be changed unless it has been contaminated with dirt, sand or metal particles.

1.Drain the gasoline from the fuel tank or run the engine until the fuel tank is empty. Drain the oil from the engine.

2.Remove four screws and remove the transmission cover and gasket. See Fig. 7-2.

Removing/Installing a Single Tine

1.With the engine shut off and the spark plug wire disconnected, remove the two screws and nuts that attach a single tine to a tine holder. If needed, use penetrating oil on the nuts.

2.When installing a single tine, be sure to position it so that its cutting edge (sharp) will enter the soil first as the tiller moves forward.

3.Remove the left-side wheel. Tilt the left-side wheel shaft into a drain pan and allow the gear oil to drain through the top of the transmission.

4.Reinstall the wheel. Install a new gasket (do not reuse the old gasket) and reinstall the transmission cover.

5.Refill the transmission using GL-4 gear oil (SAE 85W-140 or SAE 140). Refill the engine with motor oil and replenish the fuel tank with gasoline.
