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. Always follow these precautions:

• Never run the 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 and open

flame, and out of the reach of children.

• Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.

• Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or

anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank Cap and fuel container cap 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 engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel

container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.

• Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping it

away from the spark plug to prevent accidental starting, wait 5 minutes before making adjustments or repairs.

• Never check for an ignition spark with the spark plug or spark plug wire(s) 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 cover the machine while the muffler is still hot.

• Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could create

a fire hazard. Do not use flammable solutions to clean the air filter.

• The muffler and engine become very hot and can cause a severe burn; do not touch.

• Compact or Sub-Compact Tractor

Tow Vehicle Restrictions:

- You must be able to secure the Remote Control Panel of the TOW-BEHIND DR FIELD and BRUSH MOWER within easy reach

of the driver seated on the Tow Vehicle. The front of the Control Panel is 5' from the Versa-Hitch™. A Utility Vehicle with a bed longer than 2 ft. will not meet this restriction so you cannot use it as a Tow Vehicle.

- Riding Lawn Mowers with Engines under 17 HP and weighing less than 500 pounds are not suitable for use on slopes greater

than 5º.

- Never operate your TOW-BEHIND DR FIELD and BRUSH MOWER on slopes greater than 20º using any type of Tow Vehicle.

- If your Tow Vehicle will not travel by itself over the terrain you plan to use it with the TOW-BEHIND DR FIELD and BRUSH

MOWER, then it will not be suitable as a Tow Vehicle over that terrain.

Tip: Riding Lawn Mowers will work best as a Tow Vehicle with their cutting deck removed.

• We do not recommend driving over 5 mph on flat terrain and over 4 mph on rough terrain while operating your TOW-

BEHIND DR FIELD and BRUSH MOWER.

• Never use a truck (2 or 4wd) or jeep to operate the TOW-BEHIND DR FIELD and BRUSH MOWER. It would be difficult to

see and you cannot operate the mower controls from these types of tow vehicles. Using these vehicles will void the TOWBEHIND DR FIELD and BRUSH MOWER warranty.

FIELD and BRUSH MOWER

Before Starting the Engine

Inspect the area where you will be working. The site must be free of potentially hazardous obstacles such as glass, large stones, sticks, wire, rope, and string-like materials. Make sure there are no people or animals in the area around the TOW-BEHIND DR FIELD and BRUSH MOWER.

1. Check the oil level every time you use the machine (Figure 3 on page 10).

2. Check the gasoline level (Figure 3 on page 10).

3. Open the Fuel Shut-Off Valve, which is located in the Fuel Line (Figure 1 on page 7).

4. Make sure the Blade Control Knob is pushed down to the disengaged position (Figure 1 on page 7).

NOTE: The Blade Control Knob must be DOWN, or the Engine will not start.

Starting

1. Push the Blade Control Knob down to disengage the Blades (Figure 1 on page 7).

2. When starting a cold Engine, push the Throttle Control Lever up to the CHOKE position. When starting an already warm

Engine, push the Throttle Control Lever down to the RUN position (Figure 1 on page 7).

3. Turn the Key Switch to the center position (ON), and then to the START position (Figure 1 on page 7) until the Engine starts,

then release. The Key will snap back to the center position (ON) and the Engine will continue to run.

4. As the Engine warms up, slowly adjust the Throttle to the Run position. Wait until the Engine runs smoothly before each

Throttle adjustment. For maximum performance, operate the Engine with the Throttle in the RUN position.

Stopping the Engine

1. Disengage the Blades by pushing the Blade Control Knob down.

2. Move the Throttle Control Lever all the way down to the IDLE position and turn the Key to STOP.

3. Remove the Key for safety. The Key has a pressure lock that prevents it from vibrating loose during operation. To remove the

Key, push it in and then quickly and firmly pull it out. If the Key becomes difficult to remove, apply a non-conductive lubricant into the Keyhole.

NOTE: Close the Fuel Shut-Off Valve when transporting or storing the TOW-BEHIND DR FIELD and BRUSH MOWER.

Never stop the engine by moving the throttle control lever to the choke position. This could cause an engine backfire resulting in engine damage.

Engaging the Blades

1. Engage the Blades by pulling UP on the Blade Control Knob (Figure 1 on page 7).

Stopping the Blades

1. Push DOWN on the Blade Control Knob (Figure 1 on page 7).

Adjusting the Mower Deck Height

• Shut off the engine before adjusting the deck height or serious injury may result. The blades could sever your foot if it sticks

under the deck with the engine running.

• Never get off the tow vehicle without first stopping the blades and shutting off the tow vehicle engine and the TOW-BEHIND

DR FIELD and BRUSH MOWER engine.

NOTE: The TOW-BEHIND DR FIELD and BRUSH MOWER Deck has four (4) cutting heights, 4", 5-1/4", 6-1/2" and 7-3/4".

Keep your foot clear of the mower deck when adjusting the height. You could pinch your foot if it sticks under the deck.

1. To change the cutting height, apply foot pressure to the Step & Mow™

Height Adjuster (Figure 14) and at the same time, lift up on the spring loaded Deck Height Adjust Knob and re-position the Knob to the desired height in one of the four Height Adjust Notches on top of the Deck. Repeat this for the opposite side of the Deck.

NOTE: Make sure that the left and right side Adjust Knob is the same notch for both sides.

Tip: Since you previously leveled the Out-Rigger™ Tow Bar when attaching it to your Tow Vehicle, whenever you change Cutting Height position up or down, just move the Versa-Hitch™ (Figure 11 on page 13) up or down to ensure that the Tow Bar is level or slightly lower at the Tow Hitch.

16 TOW BEHIND DR

FIELD and BRUSH MOWER

Offset Mowing

The Out-Rigger™ Tow Bar allows you to offset the cutting path of the TOW-BEHIND DR FIELD and BRUSH MOWER up to 100% from the Tow Vehicle. The provided locking positions are 0%, 50%, 75%, and 100%. Offset mowing allows you to mow closer to equipment, trees, and fences and to drive in area already cut.

When performing offset mowing, always be sure that the Out-Rigger™ Tow Bar angle setting (Figure 15) and the Versa-Hitch™ angle setting match. This allows the tow-behind DR field and brush mower to track parallel to the tow vehicle.

Offset at the Tow Bar Mount Plate:

Lift the Handle of the Tow Bar Locking Pin and rotate it (Figure 15a) to align the Spring Pins with the slot in the Tow Bar. Continue lifting until both Spring Pins are above the Tow Bar.

2. Rotate the Handle again until the Bottom Spring Pin is 90º to the Slots in

the Tow Bar and lower the Handle until the Bottom Spring Pin (Figure 15b) rests on the Tow Bar. This is the unlocked position.

3. Move the Mower, using the Push Bar, until you have approximately aligned

the Tow Bar with the desired Offset angle (Figure 15).

4. Lift the Handle and twist it until the Spring Pins align with the Slots in the

Tow Bar. Press down to be sure to seat the Pin in the Mounting Plate hole (Figure 15a) at the desired location.

NOTE: If the Tow Bar alignment is correct and the Locking Pin is properly

positioned, the Upper Spring Pin will not be showing. If the Upper Pin is still visible, adjust the Tow Bar angle by moving the Mower until the Locking Pin can be pushed down into place and the Upper Pin is no longer visible (Figure 15b).

Check the owner’s manual for your tow vehicle to determine its

recommended towing capabilities on slopes.

• When operating the TOW-BEHIND DR FIELD and BRUSH MOWER over

uneven terrain or slopes, use extreme caution not to tip over the machine.

• Never use the TOW-BEHIND DR FIELD and BRUSH MOWER on slopes

greater than 20 degrees. Doing so could result in serious injury or damage to your machine.

Figure 16

50%

100%

• If you have to mow on sloping terrain, mow up and down, never across

the slo

e, for better control.

If the machine gets hung up

1. Disengage the Blades and STOP the Engine. NEVER try to free the machine from stumps or debris with the Blades engaged.

2. Try driving over or backing away from the obstacle.

• If you need to leave the tow vehicle to clear debris from the mower deck, set the parking brake and shut off the tow vehicle

engine, disengage the mower blades, shut off the TOW-BEHIND DR FIELD and BRUSH MOWER engine and disconnect the spark plug wire(s).

• Never touch the exhaust areas when reaching for the spark plugs; they may be very hot.

Cutting Brush and Saplings

1. The cutting capacity is 1-1/2" saplings.

2. When cutting woody material, small saplings, etc., allow the machine to ride up and over material slowly. Adjust your forward

speed to varying conditions.

3. After cutting brush, etc., you may want to mow over it again to remove any remaining branches. It works best to mow from

the trunk end toward the top as brush lies on the ground.

4. If you are using Offset Mowing, keep the Offset at 75% when cutting heavy brush.

Cutting Wet and Heavy Growth

1. Avoid steep slopes and other slippery areas.

2. Use a lower, slower speed when mowing in wet conditions.

Battery Care

Proper care can extend the life of a Battery. Follow these recommendations to ensure your Battery’s best performance and long life:

Figure 26

Debris Guard

• Do not allow the Battery charge to get too low. If the machine is not used,

charge the Battery every 4 – 6 weeks. Operate the Engine for at least 45 minutes to maintain proper Battery charge.

• Store an unused Battery in a dry area that does not freeze.

• Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle charger; however, when a

Battery is fully charged and the charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery will read 12V-13.2V with a voltmeter.

• Do not continue to crank the Engine when the Battery charge is low.

Daily Checklist for the TOW-BEHIND DR FIELD and BRUSH MOWER

To help maintain your TOW-BEHIND DR FIELD and BRUSH MOWER for optimum performance, we recommend you follow this checklist each time you use your machine.

[ ] Check the engine oil and Gas Tank level.

[ ] Check that Engine is clean of debris. [ ] Check the general condition of the Mower, e.g.; nuts, bolts, welds, etc. [ ] Check Tire Pressure and wear. [ ] Check the Frame for wear and damage. [ ] Check the Blades and Spindle for tightness, nicks, cracks, wear or debris that has wrapped around. [ ] Check that the Remote Control Panel is secure. [ ] check the Debris Guard for wear or damage.

End of Season and Storage

NOTE: Please refer to the Engine Owner's Manual for Engine-specific procedures.

• Change the Engine oil and Oil Filter and replace the Fuel Filter.

• Remove the Spark Plug(s) and pour about 1 ounce of motor oil into the Cylinder hole. Replace the Plug(s) and crank the Engine over a

couple of times using the Electric Starter. This will coat the pistons and seat the valves to prevent moisture buildup.

• Clean or replace the Air Filter(s).

• Clean dirt and debris from the Cylinder Head Cooling Fins, Blower Housing, Debris Screen, and Muffler area of the Engine.

• If your TOW-BEHIND DR FIELD and BRUSH MOWER 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 any wrapped weeds from the Blades Carrier Housing. Clean grass and debris from the top and underneath the mower Deck

with a stiff brush.

• Check the Blades for nicks and wear. Remove the Blades and sharpen them, or have them professionally sharpened if needed.

• 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 Blades’ 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.

• If possible, store your TOW-BEHIND DR FIELD and BRUSH MOWER inside, but not near an open flame or spark such as found in a

water heater.

• After the TOW-BEHIND DR FIELD and BRUSH

MOWER 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.
