Using Your Cutter
Getting Started
You will need to spend some time getting the “feel” of
your new cutter. Spend time reviewing the following
steps before using your cutter for the first time. The
time that you take will greatly enhance your ability to
get the desired results when you begin mowing.
9 Attach the cutter to the tractor, see the hook-up
procedures on page 8 for complete instructions.
After you have the cutter attached, double check
to ensure that no part of the tractor is in contact
with the cutter.
9 Next, follow the instructions for installing the
driveshaft on page 8 of this manual. Check to see
that all PTO guards are in place correctly.
9 Check the blades for sharpness. Check the blade
carrier castle nut and both blade bolts for
tightness. Verify that the gate valve under the oil
tank is “on”. The cutter is shipped with the gate
valve in the “off” position.
Danger
Before proceeding, make sure that no other persons
are in close proximity to the cutter!
9 With all controls in neutral, the tractor in park, the
throttle in idle position and the PTO off… Start the
tractor engine.
9 Carefully engage the tractor’s hydraulic system to
detent position, leaving the tractor PTO off.
9 Now with the cutter under power, practice using
control valve levers to control the movement of the
cutterhead, the boom arm, and the cutter head.
After you feel comfortable with the basic cutter control,
the next step is to start the blades.
9 Slowly increase the tractor throttle to a high idle
speed and slowly engage the PTO.
Danger
Do not change the blade rotation direction! Blades
must rotate in the clockwise direction indicated by the
rotation decal on the mowing deck.
9 After the cutter is running smoothly, increase the
tractor to 540 PTO RPM and adjust the cutterhead
to the mowing position.
9 Release the tractor from park and put the
transmission in low range. You are now in mowing
mode and are underway.
Caution
You will do severe damage to your cutter if you allow
the boom arm to reach the bottoming-out point.
Side Dressing Trees
The design of your heavy-duty brush cutter will allow
you to “side dress” trees if needed. Approximately 58”
above ground level with the DB-4048, and 70” above
ground level with the DB-4060. To do this tilt the
cutterhead to the vertical position. With the blades
“on” move forward slowly, removing only
approximately 12 inch depth of material per pass.
Unhook and Post Use Care
Before unhooking the tractor from your mower, always
clean the unit thoroughly to remove and grass, mud or
debris, this mower should always be stored on a hard
level surface.
Unhooking the DB-4048 & DB-4060
9 To unhook from your unit, first lower the jack
stand to the storage position.
9 Lower the deck so that it rests firmly and evenly
on the ground.
9 Lower the tractor lift arms so that the mower will
rest firmly on the jack stand.
9 Be sure to relieve all hydraulic pressure on the
extension arm and deck before unhooking.
9 Unhook tractor hitch from 3-point frame on
mower.
Post use care
• Never leave driveshaft hanging down and
touching the ground.
