Gasoline is a highly flammable liquid that gives off flammable vapor that can be ignited and cause a fire or explosion. Always
follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust contains carbon monoxide, an odorless,
tasteless, and poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose. Keep away from heat and open flame
and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged or after 5 years of use, whichever comes first.
Fill the gasoline tank outdoors with the engine off and after the engine has cooled completely. Don't handle gasoline if you or
anyone nearby is smoking.
If you spill gasoline do not start the engine. Move the machine away from the area until the gas vapors have dissipated.
Before performing engine maintenance or repairs, shut down the engine, disconnect the spark plug wire, and wait 5 minutes
for the engine to cool.
Never change the engine governor settings or modify the engine speed.
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.
Allow the engine to cool completely before storing in any enclosed area.
Keep combustible substances away from the engine when it is hot. Never cover the machine while the muffler is still hot.
To reduce fire hazard, keep the engine and muffler free of debris build-up.
Do not operate the engine with the air cleaner or the carburetor air intake cover removed.
Do not use flammable solutions to clean the air filter.
Never operate the engine without the muffler and deflector, if so equipped. Inspect the muffler and deflector periodically and
replace if necessary.
The muffler and engine become very hot and can cause a severe burn. Do not touch.

Keep your foot clear of the mower deck when adjusting the height. You could
pinch your foot if it is under the deck.
The Height Adjust Handle should always be pinned on the inside of the
Frame and in the down position for mowing. This prevents the Height
Adjuster from rotating and lowering the Deck during use.
Engaging the Blades
1. Engage the Blades by pulling up on the Blade Switch Safety Cover and
pushing forward on the Blade Control Switch (Figure 28).
Stopping the Blades
1. Push down on the Blade Control Safety Cover (Figure 26).
Adjusting the Mower Deck Height
Note: The TOW-BEHIND DR FIELD and FINISH MOWER Deck cutting Height
ranges from a minimum of 1-1/2" to a maximum of 5-1/2".
1. Remove the Locking Pin from the Height Adjuster (Figure 29).
2. Lift the Handle up to the operating position and re-install the Locking Pin
(Figure 30).
3. Repeat Steps 1 and 2 for the Height Adjuster on the opposite side.
Note: Rotating the Height Adjusters Clockwise will lower the Mower Deck. Rotating
the Height Adjusters Counter Clockwise will raise the Mower Deck. Ten full rotations
equal 1" of height change.
4. Rotate both Height Adjusters in the desired direction, switching sides about
every ten full turns, until the top of the Sway Brace is aligned with the
desired cutting height lines on the Height Adjust label. (Figure 31).
5. After the height is set the same on both sides of the machine, rotate the
Handle to the inside of the Frame, pull the Locking Pin, fold the Handle
down and insert the Locking Pin to secure the Handle in the down position.

Offset Mowing
The Tow Bar allows you to offset the cutting path of the TOW-BEHIND DR FIELD and FINISH MOWER up to 68" (Mow Pro-44
Model) and 76" (Mow Pro-60 Model) from the center of the Tow Vehicle. The various offset positions are listed in the
“Specifications” section in Chapter 2. Offset mowing allows you to mow closer to equipment, trees, and fences while the Tow
Vehicle stays at a safer distance. It also allows you to drive in an area already cut and not through grass that hasn’t been cut yet.
See the section “Changing the Tow Bar Offset Direction” on the next page to allow offsetting the Mower to the left side of the Tow
Vehicle.
Offsetting the Tow Bar:
1. Remove the Hair Pin, Washer, and Clevis Pin that secures the Tow Bar in
the Offset Bracket (Figure 33).
2. Rotate the Tow bar to the Desired Offset (No Offset, Middle Offset, or Full
Offset).
3. Reinstall the Clevis Pin, Washer, and Hair Pin to Lock the Tow Bar in Place.
Offsetting the Tow Bar Extension:
1. Remove the Hair Pin, Washer, and Clevis Pin that secures the Tow Bar
Extension to the Tow Bar (Figure 34).
2. Rotate the Tow bar Extension so that the Offset angle is the same as at the
Offset Bracket (No Offset, Middle Offset, or Full Offset).
3. Reinstall the Clevis Pin, Washer, and Hair Pin to Lock the Tow Bar
Extension in Place.

When performing offset mowing, always be sure that the Tow Bar offset and the Tow Bar Extension offset match (Figure 32). This
ensures the Tow-Behind DR Field and Finish Mower will track parallel to the tow vehicle path.
Always install the Clevis Pins from the bottom with the Washers and Hair Pins
on top to prevent the Hair Pin from being pulled out by tall grass or bushes.

Changing the Tow Bar Offset Direction
The Tow Bar can be installed for offsetting to the right or left depending on
which side of the tow vehicle you choose to mow. The following steps describe
installing the Offset Bracket to allow offsetting to the left side of the Tow
Vehicle.
1. Support the Tow Bar as you remove the Hair Pin, Washer and Clevis Pin that
secures the Offset Bracket to the Push Bar (Figure 35).
2. Turn the Tow Bar over to position the Offset Bracket for left side offset
(Figure 36).
3. Reinstall the Offset Bracket to the Push Bar with the Hair Pin, Washer and
Clevis Pin.
4. Remove the Hair Pins, Washers and Clevis Pins that are at the Tow Bar and
Tow Bar Extension offsets and reinstall with the Washers and Hair Pins on
top.
5. To adjust the offset see section “Offset Mowing” on the previous page.

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 FINISH MOWER over uneven terrain or slopes, use extreme caution not to
tip over the machine.
Never use the TOW-BEHIND DR FIELD and FINISH 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.
