Adjusting the Cutting Height
Adjusting the cutting height is easy. Cutting heights range, in ½ inch increments, from 1½
inches when using the bottom line plate, to approximately 4 inches when using the top line
plate
(Figure 14).
1. Install the cutting cords in the line
plate that gives you the desired
cutting height.
The Mow Ball Support
Allow the front end of the machine
to rest lightly on the Mow-Ball
Support as you are trimming. The
Mow-Ball™ Support should glide on
the ground as you maneuver the
machine. To achieve the best and
smoothest cut, do not lift up on the
handlebar while operating your
DR TRIMMER/ MOWER™. Lifting
the handlebar will force weight
down on the Mow-Ball Support.
This uses more energy, slows
down the cutting, and produces an
unsatisfactory cut. Ideally, the
Mow-Ball Support should lightly
rest on the ground while the
wheels balance most of the weight
of the machine (Figure 15).
Important!
When using the PTA

feature, install the cutting cords in one of

the four bottom line plates only.
