Slope Operation
Safety for Children
Tragic accidents can occur if the operator is not alert to the presence of children. Children can be attracted to the DR FRONT
TINE ROTOTILLER and the tilling activity. Never assume that children will remain where you last saw them.
Keep children out of the work area and under the watchful care of a responsible adult.
Be alert and always turn off your Tiller Engine if children enter the work area.
Before, and while moving backwards, look behind, and down for small children.
Never allow children to operate the DR FRONT TINE ROTOTILLER.
Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
Use of machinery on slopes is a major factor related to accidents, which can result in severe personal injury. Use of machinery on
slopes requires caution. If you feel uneasy using the DR FRONT TINE ROTOTILLER on a slope, do not operate it. Always take the
following precautions when using this machine on slopes:
Always:
Exercise extreme caution when changing direction on slopes.
Watch for holes, ruts, and bumps on the ground.
Operate machine across slopes, never up and down the slope.
Never:
Never operate near drop-offs, ditches, or embankments; you could lose control of your Tow Vehicle and/or the DR FRONT
TINE ROTOTILLER.
Never operate on slopes greater than 15 degrees, or on any excessively steep slope.
Never operate on wet, or slippery slopes. Reduced traction could result in tipping over your Tow Vehicle and/or the DR FRONT
TINE ROTOTILLER.

Safety with Gasoline-Powered Machines
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline and always follow these precautions:
Never run the DR FRONT TINE ROTOTILLER Engine in an enclosed area or without proper ventilation as the exhaust from the
Engine contains carbon monoxide, which is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat, open flame,
and out of the reach of children.
Fill the gasoline tank outdoors with the Engine off and allow the Engine to cool completely. Do not handle gasoline if you or
anyone nearby is smoking, or if you are near anything that could cause it to ignite or explode. Replace the Fuel Tank and Fuel
Container Caps securely.
If you spill gasoline, do not attempt to start the Engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.
Allow the DR FRONT TINE ROTOTILLER Engine to cool completely before storing in any enclosure. Never store the machine
with gas in the Tank or with gas in a Fuel Container near an open flame or spark such as a water heater.
Never make adjustments or repairs with the Engine running. Before making an adjustment or repair, shut off the DR FRONT
TINE ROTOTILLER Engine, wait five minutes to cool, then disconnect the Spark Plug Wire and keep the Wire away from the
Spark Plug to prevent accidental starting.
Never check for an ignition spark with the Spark Plug or Spark Plug Wire removed. Always use an approved Spark Tester.
Never tamper with safety devices. Regularly check their proper operation.
Never change the Engine Governor settings or modify the Engine speed. Modifications will void your warranty.
To reduce fire hazard, keep the Engine and Muffler area free of debris build-up such as leaves, grass, oil, grease, or any other
combustible material. Clean the Engine area after each use.
Never operate the Engine without the Muffler. Inspect the Muffler periodically and replace if necessary. If the Engine is
equipped with a Muffler Deflector, inspect it periodically and replace if necessary.
Never operate the Engine with the Air Cleaner or Cover over the Carburetor Air Intake removed, except for adjustment.
Removal of such parts could create a fire hazard. Do not use flammable solutions to clean the Air Filter.
Always check Fuel Lines and Fittings frequently for cracks or leaks, replace if necessary.
Replace rubber Fuel Lines and Grommets when worn or damaged, but do not use over five years.

2. Move the choke lever to the "CHOKE" position (leave the Choke "RUN"
position if the Engine is already warm)
3. Move the Throttle from the "STOP" position to about 1/4 of the way to the
fast (Rabbit) position.
4. Grasp the Recoil Starter Handle and slowly pull until you feel resistance.
Let the Cord retract a little bit, and then pull the Cord rapidly to start the
Engine.
5. When the Engine starts, move the Throttle to the Fast (Rabbit) position.
Stopping the Engine
To stop the engine in an emergency, simply turn the engine switch to the "OFF"
position. Under normal conditions, use the following procedure:
1. Move the throttle lever to the slow (Turtle) position (Figure 15).
2. Let the engine idle for one or two minutes.
3. Turn the engine On/Off switch to the "OFF" position.
4. Turn the fuel valve lever to the "OFF" position.

Handlebar Height Adjustment
Tools needed:
Two 13mm Wrenches
1. Loosen the two bottom Bolts of the Upper Handlebar using two 13mm
Wrenches (Figure 19).
2. Remove the Locknuts, Flat washers, and Hand Knobs from the top holes of
the Upper Handlebar using a 13mm Wrench.
Operating Speed
For normal tilling, set the throttle control lever to “FAST” for best tiller action.
The throttle should be set to control forward movement to a slow walking
speed for cultivating.
Set the throttle control lever to “LOW” to reduce stress on the engine when
tilling is not being performed.
Besides depth stake setting, variation of pressure on the handles also helps
further control of tilling depth and travel speed.
A downward pressure on the handles will reduce the tilling depth and
increase the forward speed.
An upward pressure on the handles will increase the working depth and
reduce the forward speed.
Tilling
Tilling is digging in, turning over and breaking up garden soil to prepare a seedbed for planting. Best tilling depth is 4" (100mm)
to 6" (150mm). A tiller will also clear the soil of unwanted vegetation. The decomposition of this vegetation matter enriches the
soil.
Avoid tilling soil that is too dry as it will pulverize and produce a dust that will not hold water. Water the area to be tilled a few days
before tilling. Also, tilling soil that is too wet will produce unsatisfactory clods. Wait a day or two after heavy rain for the soil to dry.
Better growth will be obtained if an area is tilled properly and used soon after tilling to preserve the moisture content.
The type of soil and working conditions will determine the actual setting of the tilling depth. In some soils, the desired depth is
reached first pass over garden. In other soils, the desired depth is obtained by going over the garden two or three times. In later
case, the Drag Stake should be lowered before each succeeding pass over the garden. Passes should be made across the length
and width of the garden alternately. Do not try to dig too deeply in the first pass. If the machine jumps or bucks, adjust the Drag
Stake to allow the unit to move forward at a slightly faster rate.
If the tiller stops forward motion and tries to dig in one spot, rock the handles from side to side to start it moving forward again.
Rocks which are turned up should be removed from the garden area.
Cultivating
Cultivating is loosening or digging around growing plants to disrupt weeds and aerate soil. Less than 2” (50mm) depth is always
desirable.
Idle Speed
1. Set the throttle control lever to the SLOW position to reduce stress on the engine when work is not being performed.
Lowering the engine speed will help extend the life of the engine, and will help conserve fuel and reduce noise level.

FRONT TINE ROTOTILLER
Never use a “pressure washer” to clean your unit. Water can penetrate tight areas of the machine and its transmission case and
cause damage to spindles, gears, bearings, or the engine. The use of pressure washers will result in shortened life and reduce
serviceability.

Tine Shear Pins
The DR FRONT TINE TILLER drive components are protected from damage by Shear Pins in the Tine Assemblies. The Shear Pins
hold the Tine Assemblies in the proper location on the Drive Axles. Should a Tine Assembly strike or pick up a large object and
jam, the Shear Pin holding the Tine Assembly to the drive shaft will shear, protecting the drive components of the DR FRONT
TINE TILLER from major damage. Replace Damaged or missing Shear Pins.
Engine Maintenance
For information on engine maintenance, refer to the Engine Manual included with your machine. Your engine manual provides
detailed information and a maintenance schedule for performing maintenance tasks.
NEVER attempt to use a Shear Pin that is larger or harder than the original grade of Shear Pin.

Daily Checklist for the DR FRONT TINE ROTOTILLER
To help maintain your DR FRONT TINE ROTOTILLER for optimum performance, we recommend you follow this checklist each
time you use your machine.
[ ] Check the engine oil level.
[ ] Check the gas Level
[ ] Check the general condition of the Tiller, e.g.; nuts, bolts, welds, etc.
[ ] Check belt for wear, damage or stretching.
[ ] ENGINE: It is very important to keep the Engine clean. Remove dirt and other debris from the Engine Cooling Fins. A dirty
Engine retains heat and can cause damage to internal Engine components.
[ ] HARDWARE: Check all nuts and bolts to be sure that the components are secure.
[ ] FRAME: Check all welds to be sure that the Frame is intact and secure.
[ ] TINES: Make sure that the Tine Assemblies and Debris Shield are free of accumulated debris.
End of Season and Storage
NOTE: Please refer to the Engine Owner’s Manual for Engine-specific procedures.
Change the Engine oil.
If your DR FRONT TINE ROTOTILLER will be idle for more than 30 days, we recommend using a gas stabilizer. 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 stabilizer or gasoline additive. Run
the Engine for a short time to allow the additive to circulate.
Remove the Spark Plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the Plug and pull the Recoil Starter
Rope until you feel strong resistance. This will coat the Piston and seat the Valves to prevent moisture buildup.
Clean or 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 and Wheels.
Touch up all rusted or chipped painted 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.
If possible, store your DR FRONT TINE ROTOTILLER inside, but not near an open flame or spark such as found in a water
heater.
After the DR FRONT TINE ROTOTILLER 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.
When performing any maintenance, you must first shut off the Engine; wait five (5) minutes to allow parts to cool and disconnect
the Spark Plug Wire, keeping it away from the Spark Plug.
