Approach obstacles (Buildings, fence posts, Trees, Large Rocks etc) so the 
impact zone will be within the area of the Optimum Impact Zone Label 
(

Figure 27

).  This will ensure the best spring action and trimming coverage 

around the obstacle. 

 

If you do run into debris and the Trimmer becomes tangled, 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 for parts to cool before attempting to untangle the 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. 

Heavy Growth 

 

Take your time in heavy growth. 

 

If the machine cannot do it all in one pass, overlap half of the cutting swath. 

 

Ease the DR 6.25 TOW-BEHIND TRIMMER/MOWER into denser growth.  If 
the material is too tough or woody to cut, the Cutting Cords will wrap around 
it, wear down, or even break off. 

Tip:

 Use the “two pass”, one half overlap method, whenever possible. 

Slopes 

Refer to your Tow Vehicle Users Manual for slope safety information and slope operation guidelines for the Tow Vehicle.  Never 
exceed 20 degrees slope for the DR 6.25 TOW-BEHIND TRIMMER/MOWER.  Whenever possible, try to trim with the Trimmer 
Head DOWN HILL from the machine. 

Windrows 

The DR 6.25 TOW-BEHIND TRIMMER/MOWER Cutting Cords cut even tall grass in just one pass, so you can collect clippings 
and leaves for mulch without raking.  The machine ejects cut material to its left side, so you can use it like a lawn broom to make 
windrows for easy clean-up. 

Cord Tips 

We ship two thicknesses of Cutting Cord with your DR 6.25 TOW-BEHIND TRIMMER/MOWERS.  The Cords are Blue (175-mil) 
and Green (155-mil).  Because conditions and vegetation vary, you should experiment with Cord weights (diameters) to discover 
what works best for your particular mowing and trimming situations.  Here are a few things to keep in mind: 

 

If you buy Cutting Cord in rolls, cut it in 25" lengths.  Cut them at an angle so they will be easier to install. 

 

Soak your Cutting Cord in a bucket of room temperature water for a few days before use to make it more pliable.  Storing the 
Cord in a plastic bag with a damp sponge or cloth will help keep it pliable 

 

Cord life depends on trimming conditions.  Replace Cords when they become broken or frayed. 

 

The smallest diameter Cord capable of cutting the material at hand usually provides the best grass trimming performance.  
When you need more strength for thicker growth such as berry canes, brambles, thistles, or ragweed, you may want to use the 
175-mil Cord. 

 

Ease the ends of the Cord into heavy growth and move slowly through thick growth.  If there are woody weeds in the material 
you are cutting, the cutting Cords may wrap around the stalks they cannot cut, and pull away from the Trimmer Head. 

 

If the Cord breaks off flush at the Line Plate, use needle nose pliers to pull out the old Cord. 

 

UV light can degrade cord, store out of direct sunlight.
