Important Safety Information
Always wear appropriate safety gear, including eye protection, when operating the tiller. Be aware of the tines' movement and keep hands and feet clear. Never fuel the tiller with the engine running or while the engine is hot. Always turn off the engine and allow it to cool before refueling.
- Read the entire manual before operating the machine.
- Keep children and pets away from the operating area.
- Inspect the area for rocks, debris, or other objects that could be thrown by the tines.
- Operate only in well-ventilated areas.
- Do not operate the tiller under the influence of alcohol or drugs.
Setup and Assembly
The Earthquake Versa Tiller Cultivator is designed for straightforward assembly. Follow these steps to prepare your unit for operation:
- Handlebar Assembly: Attach the upper handlebar to the lower handlebar using the provided hardware. Ensure all bolts are securely tightened. The handlebar height is adjustable for user comfort.
- Wheel Installation: The onboard wheels are designed for simple transportation. Ensure they are properly attached and can be easily engaged or disengaged for tilling.
- Tine Configuration: The tiller features tool-less removal of side shields and outer tines. This allows you to adjust the tilling width from 11 inches for cultivation to 21 inches for wider tilling. Ensure tines are securely fastened for your desired width.
- Fuel and Oil: Fill the engine with unleaded gasoline and the appropriate 4-cycle engine oil as specified in the engine manual. Do not overfill.

Operating Instructions
Before starting, ensure the unit is on a level surface and all safety precautions have been observed.
- Starting the Engine:
- Ensure the fuel valve is open and the engine switch is in the 'ON' position.
- Apply choke if the engine is cold.
- Pull the recoil starter handle firmly until the engine starts.
- Gradually open the choke as the engine warms up.
- Tilling and Cultivating:
- Engage the tines by squeezing the control lever on the handlebar.
- Guide the tiller forward, allowing the tines to dig into the soil. The tilling depth can reach up to 11 inches.
- For initial tilling of hard soil, make shallow passes first, then gradually increase depth with subsequent passes.
- For cultivating, use a narrower tine setting and lighter passes to mix soil, aerate, or remove weeds.
- Stopping the Engine: Release the control lever and move the engine switch to the 'OFF' position.
