DR ® TRIMMER/MOWER ™ Safety & Operating Instructions 15
Figure 6
Using PTA  (Parallel Trimming Action)
Your trimmer’s PTA  feature moves the machine in a straight line while the trimmer head is
both pivoted and tilted to the left for better access to fence lines and other obstacles. PTA 
allows you to trim in difficult areas without having to pull the machine back and forth.
The following two sections explain how to engage PTA  and how to return your trimmer to
flat and forward mode (normal operation) after using PTA  .
Note: In PTA
 mode, the trimmer’s
wheels stay straight while trimmer
head tilts as shown in Figure 6.
The cutting cords extend beyond
the wheelbase in the PTA
 mode,
allowing you to easily cut under
obstacles. The trimmer head and
the cutting cords also tilt slightly in
PTA
 mode so you can edge and
trim along gardens, paths, and
driveways.
When using PTA  along garden
edges, fences, and buildings, we
recommend making your first past
with the DR
 TRIMMER/ MOWER 
in the regular mowing position,
staying 4 to 8 inches from the
obstacle. Then return for another
pass with the machine in PTA

mode.
WARNING! Use caution when edging along gravel paths and
driveways. Flying debris can cause serious damage.
Important! When using PTA
 , you should install the cutting cords in one
of the bottom four line plates only. Using the upper line plates may cause
the cords to hit the wheel. For more information, see Your Machine’s
Cutting Cords on page 16.
