Chapter 3: Operating the DR 7.25 ALL-TERRAIN TRIMMER/MOWER
Operation Notes
 See the Owner’s Manual that came with your Tow Vehicle for all safety warnings and detailed information for operating your
Tow Vehicle properly.
 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.
 Always operate the Trimmer Engine at full throttle when trimming.

Always lock the Parking Brake and shut off the Tow Vehicle when leaving the Seat.

Never transport the Trimmer while the Trimmer Engine is running.

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.
 Remove any debris buildup from the machine before every use of the Trimmer.
 Always set the Caster wheel so the Trimmer Head is the furthest off the ground when transporting the Trimmer. See
“Preparing the Trimmer/Mower for Transport” in this Chapter.
Preparing the Trimmer/Mower for Trimming
The characteristics of cutting height and quality are controlled by a combination
of the Cord Head height and Caster Wheel Spacer arrangement. It takes time
and practice to learn what the best combinations of settings for different
conditions are.
Installing Trimmer Cords
Always make sure to install all four Trimmer Cords and ensure they are the
same length. Not having all four Cords installed and/or at the same length will
cause excessive vibration and could damage the machine.
1. Insert the end of a Trimmer Cord into the inlet hole (larger slotted cutout)
push it in until the end protrudes out the other side approximately 1/2"
(Figure 9).
2. Turn the Cord Head 90 degrees and repeat the installation until all Cords are installed.
Note: The Cord can only move through the Cord Head in one direction. To remove it you must pull it from the other side of the Holder
(where the 1/2" end is).
Adjusting the Cord Cutting Height

This machine is designed to operate at full throttle for desired trimming quality. Never trim at a slower speed; doing so can
cause stress to the drive system and could cause damage to the machine that is not covered under warranty.

Read and understand your Tow Vehicle user’s manual and all safety Warnings for operating your Tow Vehicle safely before
operating this DR 7.25 All-Terrain Trimmer/Mower.
