Transmission Gear Oil

Check the transmission gear oil after every 30 hours of operation or whenever you notice any oil leak. Operating the tiller when the transmission is low on oil can result in severe damage.

To Check the Transmission Gear Oil Level:

1.Check the gear oil level when the transmission is cool. Gear oil will expand in warm operating temperatures and this expansion will provide an incorrect oil level reading.

2.With the tiller on level ground, pull the Depth Regulator Lever all the way up.

3.Remove the oil fill plug from the transmission housing and look inside the oil fill hole to locate the main drive shaft situated below the hole. Refer to Fig. 6-1.

4.The gear oil level is correct if the gear oil is approximately halfway up the side of the main drive shaft.

5.If the gear oil level is low, add gear oil as described below. If the gear oil level is okay, securely replace the oil fill plug.

6.If adding only a few ounces of gear oil, use API rated GL-4 or GL-5 gear oil having a viscosity of SAE 140, SAE 85W-140 or SAE 80W-90. If refilling an empty transmission, use only GL-4 gear oil having a viscosity of SAE 85W-140 or SAE 140.

7.While checking frequently to avoid overfilling, slowly add gear oil into the oil fill hole until it reaches the halfway point on the drive shaft.

8.Securely replace the oil fill plug.

Lubrication

After every 10 operating hours, oil or grease the lubrication points shown in Fig. 6-2 and described below.

Use a clean lubricating oil (#30 weight motor oil is suitable) and a clean general purpose grease (grease containing a metal lubricant is preferred, if available).

•Remove the wheels, clean the wheel shaft and apply a thin coating of grease to the wheel shaft.

•Grease the back, front and sides of the depth regulator lever.

•Remove the tines and clean the tine shaft. Use a file or sandpaper to gently remove any rust, burrs or rough spots (especially around holes in shaft). Apply grease to the ends of shaft before installing the tines.

•Oil the threads on the handlebar height adjustment screws and the handlebar attaching screws.
