Operating the Trimmer/Mower Safely 

A Note to All Users  

No list of warnings and cautions can be all-inclusive.  If situations occur that are not covered by this manual, the operator must 
apply common sense and operate this DR 6.25 TOW-BEHIND TRIMMER/MOWER in a safe manner.  Contact us at 
www.DRpower.com or call 1-800-DR-OWNER (376-9637) for assistance. 

This is a high-powered machine, with moving parts operating with high energy at high speeds.  You must operate the machine 
safely.  Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area.  Keep in mind that the 
operator or user is responsible for accidents or hazards occurring to other people, their property, and themselves.  Always take the 
following precautions when using this machine: 

 

Be cautious when trimming in reverse and do not hit any obstacles.  The machine is designed to spring out of the way when 
hitting obstacles in the forward direction, not the reverse direction.  If you hit obstacles with the Trimmer in the reverse 
direction the trimmer could be damaged and is not covered by the Warranty. 

 

Know how to stop the Trimmer quickly by shutting off the engine. 

 

Never allow people who are unfamiliar with these instructions to use the DR 6.25 TOW-BEHIND TRIMMER/MOWER.  Allow 
only responsible individuals who are familiar with these rules of safe operation to use your machine. 

 

Do not exceed 1-3 mph when trimming to allow proper cutting and discharge of material. 

 

Do not exceed 5 mph when transporting to prevent damage to the machine. 

 

Operating your Trimmer/Mower with the head misaligned with the ground can result in poor cut quality, pivoting problems, 
scalping during cutting, wear on your equipment, and damage to the cutting cord 

 

Never place your hands, feet, or any part of your body on or under the mower deck in the path of the spinning cords, belt, 
pulleys, or near the discharge opening while the machine is running.  Keep area of discharge clear of people, animals, 
buildings, glass, or anything else that will obstruct clear discharge, cause injury, or damage. 

 

Your DR 6.25 TOW-BEHIND TRIMMER/MOWER is a powerful tool, not a plaything.  Exercise extreme caution at all times.  
The design of your machine is for trimming and mowing grass, weeds, and other growth as specified in this manual.  Do not 
use it for any other purpose. 

 

Whenever you leave the operating position to make adjustments, change cords or if you have to remove grass or debris from 
the underside of the deck, always shut off the Tow Vehicle, set the parking brake and remove the Key.  Shut off the Trimmer 
Engine and after all moving parts to come to a complete stop, then wait five minutes before performing any maintenance 
procedure or inspection on the Trimmer. 

 

Be mindful of roll over hazards, changes in terrain, slopes, or wet conditions. Use care when backing up. 

 

Stop the cutting cords when crossing gravel drives, walks, or roads. 

 

Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR 6.25 TOW-BEHIND 
TRIMMER/MOWER.  This includes all shields and guards.  Modifications to your machine could cause personal injuries and 
property damage and will void your warranty. 

 

If the cutting cords strike a foreign object or if your machine should start making an unusual noise or vibration, shut off the 
Tow Vehicle, set the parking brake and remove the Key.  Shut off the Trimmer Engine and after all moving parts to come to a 
complete stop, wait five minutes before inspection.  Vibration is generally a warning of trouble.  Clean and repair and/or 
replace damaged parts. 

 

While using the DR 6.25 TOW-BEHIND TRIMMER/MOWER, do not hurry or take things for granted.  When in doubt about 
the equipment or your surroundings, stop the machine and take the time to look things over.  Make sure that you have 100% 
control of the Trimmer at all times. 

 

Watch for traffic when mowing near roadways. 

 

Use the machine only in daylight. 

 

Be cautious when using your DR 6.25 TOW-BEHIND TRIMMER/MOWER around fencing, wires, ropes, and hoses.  It is 
possible that these and other debris can become wound around the Trimmer Head of the machine, potentially damaging the 
bearings or injuring you. 

 

Do not operate the DR 6.25 TOW-BEHIND TRIMMER/MOWER on slopes greater than is recommended in your Tow Vehicle’s 
user manual. 

 

Keep all nuts and bolts tight and keep the equipment in good operating condition.
