Slope Operation

 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 TOW-BEHIND DR FIELD and BRUSH MOWER on a slope, do not operate it. Always take the following precautions when using this machine on slopes:

ALWAYS:

 Operate the machine up and down the face of slopes and avoid going across. Exercise extreme caution when changing

direction on slopes.

 Remove objects such as glass, large sticks, stones, metal objects, wire, rope, and string-like material.  Watch for holes, ruts, and bumps on the ground.

NEVER:

 Never operate near drop-offs, ditches, or embankments; you could lose control of your tow vehicle and/or the TOW-BEHIND

DR FIELD and BRUSH MOWER.

 Never operate on slopes greater than 20 degrees, or on any excessively steep slope. See the operating parameters section on

page 21 for further restrictions relating to your tow vehicle.

 Never operate on wet, or slippery slopes. Reduced traction could result in tipping over your tow vehicle and/or the TOW-

BEHIND DR FIELD and BRUSH MOWER.

 Never park the tow vehicle on a steep grade or slope.

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.

About the Battery

The Pro and Pro-XL TOW-BEHIND DR FIELD and BRUSH MOWERS come with a 12-Volt, maintenance-free, rechargeable, sealed lead acid Battery. Properly maintained and charged, the Battery provides years of dependable service.

 Never modify the TOW-BEHIND DR FIELD and BRUSH MOWER’S electrical system. Modifications could ruin the electrical

system as well as cause a fire, resulting in serious injury.

 Using electrical components other than those supplied with your machine could cause the electrical system to overheat,

explode, or start a fire.

 Using the wrong type of battery or charger could cause a fire or explosion, resulting in serious injury.  Use the charger only in dry locations. Avoid contact with water.  Only adults should handle the battery. It contains sulfuric acid (an electrolyte) and the battery is heavy; dropping it could

result in serious injury.

 Never allow children to charge the battery. THE ELECTRICITY INVOLVED IN CHARGING THE BATTERY COULD CAUSE

SEVERE INJURY.

 Examine the charger, its connectors, and the battery for excessive wear or damage each time you charge the battery. Replace

any components showing excessive wear or damage.

 Never lift or carry the battery by the cables or terminals. This can damage the battery and possibly start a fire, resulting in

serious injury. Lift and carry the battery only by its case.

 Do not short circuit the battery.  Read the safety instructions on the battery.

Connecting the Battery Wire (Pro and Pro-XL models)

We ship all Electric-Starting machines with the negative (ground) Battery Wire disconnected. This prevents the Battery from discharging during shipment. Before using your TOW-BEHIND DR FIELD and BRUSH MOWER, you must connect the negative (ground) Battery Wire.

Tools Needed:

 Two 5/16" Wrenches  Cutting Pliers

Green Negative

When attaching the Negative (ground) Wire, make sure you position and attach the Wire so that it will not rest on or near the Muffler. The heat from the Muffler will melt the coating and create a fire hazard causing harm to the machine and/or yourself.

1. Connect the Green negative wire to the negative terminal on the Battery with

two 5/16" Wrenches (Figure 3).

NOTE: The Bolt and Nut come with the Battery.

Chapter 3: Operating The TOW-BEHIND DR FIELD and BRUSH MOWER

This chapter covers the procedures for starting and stopping your new TOW-BEHIND DR FIELD and BRUSH MOWER and discusses basic operation features. You may find it helpful to review the TOW-BEHIND DR FIELD and BRUSH MOWER Controls and Features on page 7 before reading this chapter.

 This machine is designed for cutting grass and brush. Never use this machine for any other purpose as it could cause serious

injury.

 Contact with internal rotating parts will cause serious personal injury. Never put hands, face, feet, or clothing under the deck

or near the discharge area with the engine running.

 Before performing any maintenance procedure or inspection, stop the engine and wait five (5) minutes to allow all parts to

stop and cool. Disconnect the spark plug wire(s) keeping it away from the spark plug(s).

Operating Parameters

We recommend a few types of Tow Vehicles for the TOW-BEHIND DR FIELD and BRUSH MOWER. The Tow Vehicle may be either 2 or 4 wheel drive, but some vehicle types are not suitable for rough, hilly terrain or heavy brush conditions. See the Tow Vehicle Restrictions section below.

 ATV  Lawn/Garden Tractor (17 HP and above and weighing at least 500 pounds)  Riding Lawn Mower (14 HP and above and weighing at least 400 pounds)  Utility Vehicle  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.

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.

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", 6-1/4" and 7-1/2".

Keep your foot clear of the mower deck when adjusting the height. You could pinch your foot if it sticks under 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 17 on page 16) up or down to ensure that the Tow Bar is level or slightly lower at the Tow Hitch.

20 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 24) 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:

1. Lift the Handle of the Tow Bar Locking Pin and rotate it (Figure 25a) 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 25b) 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 24).

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 25a) 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 Spring 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 Spring Pin is no longer visible (Figure 25b).

5. Rotate the Handle to position the Upper Spring Pin out of alignment with

the Slot in the Tow Bar (Figure 25a).

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

Figure 26

50%

100%

75%

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.

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

the slope, 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

 The cutting capacity is 1" for the Premier Model and 1-1/2" saplings for the Pro and Pro-XL Models.  When cutting woody material, small saplings, etc., allow the machine to ride up and over material slowly. Adjust your forward

speed to varying conditions.

 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.

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

Cutting Wet and Heavy Growth

 Avoid steep slopes and other slippery areas.  Use a lower, slower speed when mowing in wet conditions.

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

 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.
