SERVICE AND MAINTENANCE
Removing/Installing a Single Tine
1. With the engine shut off and the spark plug wire disconnected, remove the
two hex screws (3⁄8-16 x 1.00) and hex lock nuts (3⁄8-16) 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.
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 hex screw (3⁄8-16 x 1.75) and flange lock nut (3⁄8-16 ) 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.
2. Drain the oil from the engine.
3. Remove the hex washer screw (1⁄4-20 x .500) and flat washer (.28 x .74 x
.500) from the left side of the belt cover (if so equipped) and the hex washer
screw (1⁄4-20 x .500) from the right side of the belt cover. Remove the belt
cover. See Figure 26.

5. Remove the four hex screws (5⁄16-18 x .75) securing the transmission cover to the
drive shaft and remove the cover. See Figure 27.
6. 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.
7. Reinstall the wheel and reinstall the transmission cover.
8. Refill the transmission using Mobil 1® Synthetic 75W 140. Refill the engine
with motor oil and replenish the fuel tank with gasoline.
9. Reinstall the belt cover.
Off-Season Storage
When the tiller won’t be used for an extended period, prepare it for storage as
follows:
1. Clean the tiller and engine.
2. Do routine tiller lubrication and check for loose parts and hardware.
3. Protect the engine and perform recommended engine maintenance by
following the storage instructions found in the Engine Operator’s Manual.
Be sure to protect the fuel lines, carburetor and fuel tank from gum deposits
by removing fuel or by treating fuel with a fuel stabilizer (follow the engine
manufacturer’s recommendations).
4. Store the tiller in a clean, dry area.
5. Never store the tiller with fuel in the fuel tank in an enclosed area where
gas fumes could reach an open flame or spark, or where ignition sources are
present (space heaters, hot water heaters, furnaces, etc.).
