Tips & Tricks (Tow-Behind Models)

The following information is provided to demonstrate proper techniques when operating your DR^® Tow-Behind Roto-Tiller.

Tilling

• In compacted soil or sod, or in food plot and sod busting applications, several passes may be necessary to till to a depth of seven (7) inches. For the first pass, just scratch the surface. The depth for each successive pass needs to be determined by individual site and soil conditions. If the machine stalls repeatedly, you should till slower or not as deep.
• Check the ground moisture. Do not till if you can make a ball of soil in your hand from the ground to be tilled; it is too wet. Create full tillage (depths up to 7") after entire area is dry.
• To obtain the most efficient tillage, operate the DR^® Tow-Behind Roto-Tiller engine at full throttle at the slowest speed of your tow vehicle.
• When operating the machine for the first time, proceed slowly and carefully until you become familiar with the proper method of operating the machine.
• Soil conditions will determine how deep the machine can penetrate on the first pass.
• In damp soil, till only the top inch of seedbed. Allow tillage to dry for several hours in sunny and/or windy conditions.
• Listen to your DR^® Tow-Behind Roto-Tiller engine. When the engine RPM decreases or stalls (overloaded condition) raise the Tines for shallower tilling. If the engine is lightly loaded, lower the tines to increase the tilling depth.
• If the soil is extremely hard and dry, it may be desirable to "cross till" an area at a shallow depth first, then till the soil in the direction of planting rows on subsequent passes until the desired tillage is obtained.
• 

  Where possible, we recommend that you till in a pattern similar to shown.

  1. Make the first pass.
     NOTE: If you raise the tines at the end of a pass, use care to lower them back to the same depth. Tilling too deep on the first pass may cause the Tiller to stall or break shear pins.
  2. Skip a space equal to the width of the machine.
  3. Make the return pass.
  4. Till the skipped areas.

Handling and Transporting (Tow-Behind Models)

We recommend using two (2) people to lift the DR^® Tow-Behind Roto-Tiller. Lift the machine by the SMOOTH-TRAK™ Hitch to connect and disconnect from your tow vehicle. To transport the machine with your tow vehicle, first raise the tines to the MAX position (lower the wheels) using the control box.

End of Season and Storage

The following information is provided to demonstrate proper techniques when storing your DR^® Roto-Tiller.

End-of-Season Procedure

• Change the engine oil. This will help to eliminate sludge and acids in the engine. For winter use, use SAE 5W-30W oil.
• Remove the spark plug(s) and pour about 1 ounce of motor oil into the cylinder hole. Replace the plug and pull the recoil starter rope (if equipped) or crank the engine over using the electric start. This will coat the piston and seat the valves to prevent moisture buildup.
• If your DR^® Roto-Tiller will be idle for more than 30 days, we recommend using DR^® Ethanol Fuel Treatment. This will prevent sediment from gumming up the carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the tank. Completely fill the tank with fresh, unleaded gas and add the appropriate amount of fuel treatment. Run the engine for a short time to allow the additive to circulate.
• Clean/replace the engine air filter. Reference the Engine Owner's Manual.
• Clean dirt and debris from the engine cylinder head cooling fins, debris screen, and muffler.
• Clean out residual debris from the under the debris shield and tine assemblies.
• Lubricate the tine assemblies. See your Owner's Manual.
• Touch up all rusted or chipped paint surfaces. Sand them lightly before painting.
• Be sure all nuts, bolts, and screws are securely fastened.
• Inspect moving parts and the tine drive belt for damage and wear; replace if necessary.
• Store the battery in a dry area that will not freeze. If you will not use the machine over a long period, charge the battery every four to six weeks. See your Owner's Manual for Battery Care.
• If possible, store your DR^® Roto-Tiller inside, but not near an open flame or spark such as found in a water heater.
• After the DR^® Roto-Tiller has cooled, cover the machine with a suitable protective cover that does not retain moisture. Do not use plastic as this material cannot breathe; it also allows condensation to form, which will cause your machine to rust.

• Inspect moving parts and the tine drive belt for damage and wear; replace if necessary.
• Store the battery in a dry area that will not freeze. If you will not use the machine over a long period, charge the battery every four to six weeks. See your Owner's Manual for Battery Care.
• If possible, store your DR^® Roto-Tiller inside, but not near an open flame or spark such as found in a water heater.
• After the DR^® Roto-Tiller has cooled, cover the machine with a suitable protective cover that does not retain moisture. Do not use plastic as this material cannot breathe; it also allows condensation to form, which will cause your machine to rust.
