Protecting Yourself and Those around You
This is a high-powered machine with moving parts operating at high speeds. Always take the following precautions when
operating this machine:
Always wear protective goggles or safety glasses with side shields.
We recommend wearing sturdy shoes with non-slip tread, long pants, and gloves while using this machine. Be sure the
gloves fit properly and do not have loose cuffs or drawstrings.
Use ear protectors or ear plugs.
Allow only responsible adults who are familiar with these safety rules and operating instructions to use your DR FINISH
MOWER.
Keep your hands and feet away from the blades, belt, pulley, and concealed areas while the engine is running.
Keep people and pets away from your machine and out of the work area at all times. Disengage the blade and stop the engine
if a person or pet is within 100 feet of the machine.
Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last
saw them.
Never allow people to ride on the mower.
Before mowing, clear the area of objects such as rocks, toys, wire, bones, sticks, etc.
Never remove or alter standard parts or add anything to the DR FINISH MOWER, especially all shields and guards.
Before and while moving backwards, look behind, and down for small children.
Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
Safety with Gasoline - Powered Machines
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.

Slope Operation
Use of machinery on slopes is a major factor in outdoor power equipment accidents. All slopes require caution. If you feel uneasy
on a slope, do not mow it. Always take the following precautions when using this machine on slopes:
Operate the machine up and down the face of slopes. Exercise extreme caution when changing direction on slopes.
Never operate near drop-offs, ditches, or embankments or on slopes greater than 20 degrees.
Never operate on wet or slippery slopes.
Never park the tow vehicle on a steep grade or slope.
General Safety
Safe operation of the TOW-BEHIND DR FINISH MOWER is necessary to prevent death or serious injury. Always take the
following precautions when operating this machine:
The TOW-BEHIND DR FINISH MOWER is designed to mow grass. Do not use it for any other purpose.
If the machine makes an unusual noise or vibration or if there are obstructions underneath the machine, shut off the tow
vehicle and the DR FINISH MOWER engines. Wait five minutes for the engine to cool. Disconnect the spark plug wire and
then inspect the machine for clogs or loose parts. Clear any obstructions and repair and/or replace damaged parts.
The mower blades are sharp. Wrap the blades or wear gloves and use extra caution when servicing.
Always keep the machine in good, safe operating condition. Always make certain nuts and bolts are tight. Do not use
substitute hardware.
Use the TOW-BEHIND DR FINISH MOWER only in daylight.
Always give undivided attention to the machine and your surroundings. Watch for traffic when mowing near roadways.
Disengage the mower blades and exercise extreme caution when on or crossing drives, walks, or roads.
If leaving the machine, shift the tow vehicle into neutral and set the parking brake; turn off the tow vehicle engine and remove
its key. Turn off the DR FINISH MOWER engine and remove its key.
Do not operate the mower when under the influence of alcohol, drugs, or medication.
Do not operate the mower when there is a risk for lightening.

Attaching the Tow Bar to the Push Bar
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. See section “Offset
Mowing” in Chapter 3 to determine how the Tow Bar should be installed for
your needs. The following steps describe positioning the Offset Bracket to
allow offset to the right side of the Tow Vehicle.
1. Secure the Offset Bracket to the Push Bar in the configuration shown (for
right side offset) using the 4.5" long Clevis Pin, Washer, and Hair Pin
(Figure 18).
2. Align the Tow Bar so it is pointed straight out from the Mower and install a
Clevis Pin, Washer, and Hair Pin in the Offset Bracket to lock the Tow Bar in
position.
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.
3. Align the Tow Bar Extension with the Tow Bar and install a Clevis Pin,
Washer, and Hair Pin in the Tow Bar to lock the Tow Bar Extension in place
(Figure 19).
4. Raise the Deck (see “Adjusting the Mower Deck Height” in Chapter 3) and
with a helper, roll machine backwards off Pallet. You May need to use a bar
to lift deck over the Blocks if it gets hung up.
