Your DR TRIMMER/MOWER Gear-Driven Power Take-Off System aerator attachment slices through the
top layer of sod to help deliver water, air, and nutrients to the roots of your plants. The cultivator
attachment is similar in appearance to the aerator with the exception of its alternating bent blades (see
Figure 1 on Page 7). These blades allow the cultivator to churn weeds and dead material over into the
soil as you move your machine. Use the cultivator to maintain garden beds you have previously prepared

CHAPTER 4
USING YOUR DR GEAR-DRIVEN POWER TAKE-OFF SYSTEM AND ACCESSORIES
This chapter covers the procedures for operating your new DR TRIMMER/MOWER Gear-Driven Power
Take-Off System and also discusses basic operation features.
THE TRANSMISSION IS HOT DURING AND AFTER USE. TYPICAL SURFACE TEMPERATURES RANGE
BETWEEN 110 AND 180° FAHRENHEIT. DO NOT TOUCH THE TRANSMISSION UNTIL A COOL
DOWN PERIOD OF 15-30 MINUTES HAS PASSED. COOL DOWN TIME CAN VARY DEPENDING ON
THE OUTDOOR TEMPERATURE AND OPERATING CONDITIONS.
Before using your trimmer’s accessories, be prepared to resist the force the accessories create.
THE EDGER, AERATOR, AND CULTIVATOR PULL THE TRIMMER FORWARD, AWAY FROM YOU. THE
FORCE YOU EXPERIENCE VARIES DEPENDING ON THE HARDNESS OF THE SOIL AND THE NUMBER
OF ROCKS YOU ENCOUNTER. TYPICALLY, YOU WILL NEED TO PULL BACKWARD AS THE MACHINE
PULLS FORWARD. IF YOU RESIST THE PULL OF THE MACHINE, THE ATTACHMENTS OPERATE MORE
EFFECTIVELY. IF YOU PROVIDE LITTLE RESISTANCE, THE ATTACHMENTS WILL OPERATE LESS
EFFECTIVELY. YOU MAY WANT TO PULL THE MACHINE BACKWARD FOR OPTIMUM PERFORMANCE.
WHEN USING THE DR TRIMMER/MOWER SELF-PROPELLED MODEL, DO NOT ENGAGE THE WHEEL
DRIVE WHEN USING THE ATTACHMENT ACCESSORIES. YOU WILL NEED TO RESIST THE PULLING
FORWARD ACTION OF THE ATTACHMENTS AS MENTIONED ABOVE, WHICH MAY RESULT IN DAMAGE
TO THE SELF-PROPELLED DRIVE SYSTEM IF IT IS ENGAGED. THE PTO ATTACHMENTS WILL PULL THE
MACHINE FORWARD WITHOUT ENGAGING THE DRIVE SYSTEM.
To operate the DR TRIMMER/MOWER with accessories attached:
1. Engage the Gear-Driven Power Take-Off System by pulling the bail bar of the machine back against
the handle.
2. Disengage the Gear-Driven Power Take-Off System by releasing the bail bar.
12 DR® TRIMMER/MOWER™ GEAR-DRIVEN POWER TAKE-OFF SYSTEM™
Edger Use
The Edger is designed to cut a clean straight edge in sod and grass along sidewalks and driveways.
1. When transporting the DR TRIMMER/MOWER with the Edger attachment (see Figure 1) to the site
where you wish to use it, be sure to push down on the handlebars to raise the Edger so that it does
not scrape along the ground. If the Edger scrapes along the ground or is bumped, it may unlock
from the PTO and rotate backwards. This may cause the Edger to fall off of the PTO. If the Edger is
installed on the operator’s right side, it may also unlock and loosen during use. The Edger must be
installed on the operator’s left side for proper functioning of the Edger (see Figure 8).
2. Align the Edger with the line of cut that you wish to make. If you are cutting beside a sidewalk, it is
best to have most of the machine on the sidewalk and one tire on the grass.
3. When you are at the site where you wish to edge, start the DR TRIMMER/MOWER engine; then
push down on the handlebars to lift the Edger off of the ground. Pull the bail bar back to engage the
PTO and start the Edger rotating.
4. Hold back on the handlebars and slowly lower the Edger into the ground. The weight of the DR
TRIMMER/MOWER will cause the Edger to cut into the sod and try to pull the machine forward as it
cuts. Hold the DR TRIMMER/MOWER back so that the Edger cuts completely down into the sod
and the hub of the Edger is on top of the ground.
5. Continue to hold back on the handlebars and slowly allow the Edger to work forward to cut new sod
and grass. A back and forth motion, by letting the machine move slowly forward and then pulling it
slowly back towards you, is sometimes more effective than trying to move steadily forward.
6. After you have completed your cut, you will need to pick up any sod that is cut off that you wish to
discard or compost. It is best to pick up this sod right away so that it doesn’t get packed back down
into the cut you just made. A straight edged shovel or hoe is best for picking up the loose sod.
Cultivator Use
The cultivator is designed to fluff up soil that has previously been tilled, such as a flower or vegetable
garden, to churn in fertilizer, prepare the soil for planting, or remove weeds.
1. When transporting the DR TRIMMER/MOWER with the Cultivator attachment (see Figure 1) to the
site where you wish to cultivate, be sure to push down on the handlebars to raise the Cultivator
blades so that they do not scrape along the ground. If the blades bump or scrape along the ground,
they can become unlocked and rotate off of the PTO.
2. When you are at the site you wish to cultivate, start the DR TRIMMER/MOWER engine. Hold back
on the machine as you pull back on the bail bar to engage the PTO. As the Cultivator blades start to
churn into the soil, they will try to pull the machine forward.
3. Continue to hold back on the handlebars and slowly allow the Cultivator to pull the machine forward
to cultivate new soil. A back and forth motion, by letting the machine move slowly forward and then
pulling it slowly back towards you, is sometimes more effective than trying to move steadily forward.
4. Some users prefer to continually pull the cultivator backward to maximize the work being done to
churn the soil. We recommend trying both approaches and selecting the approach that works best
for you.
CALL TOLL FREE 1-800-DR-OWNER 13
Aerator Use
The Aerator is designed to cut grooves into the sod so that water and nutrients can penetrate the sod
and get directly to the root system.
1. When transporting the DR TRIMMER/MOWER with the Aerator attachment (see Figure 1) to the site
where you wish to aerate, be sure to push down on the handlebars to raise the Aerator blades so
that they do not scrape along the ground. If the blades bump or scrape along the ground, they can
become unlocked and rotate off of the PTO.
2. When you are at the site you wish to aerate, start the DR TRIMMER/MOWER engine. Hold back on
the machine as you pull back on the bail bar to engage the PTO. As the Aerator blades start to
churn into the soil, they will try to pull the machine forward.
3. Continue to hold back on the handlebars and slowly allow the Aerator to pull the machine forward to
cut into new soil.
4. Continue to let the Aerator work around the yard, spacing your passes so that the Aerator grooves
are approximately evenly spaced. Dividing your lawn into smaller sections and then working around
each section until it is aerated is an effective way to make steady progress. Each area that is
completed is then ready for application of fertilizer and water.
