CHIPPER ATTACHMENT
The Chipper is designed to accept wood only. The Chipper Knife mounted on a revolving flywheel turns branches fed into the
Chipper Hopper into “chips”. The Chipper can chip branches ranging in size up to 3-1/2" in diameter. Cut your branches into
manageable lengths before feeding them into the Chipper Hopper.

Your DR CHIPPER ATTACHMENT can process dry or green wood up to 3.5" in diameter.

Green wood will process quicker and easier than dry wood.

Softwood processes easier than hardwood.
 Your operator experience will teach you how different types of wood will chip and how fast you can process them.
 When chipping branches, sometimes a tail will develop at the end of a branch. To avoid this, rotate the branch while feeding it
into the Chipper Hopper.

Rotating the branch as you feed it into the machine will improve chipping performance.
 Use caution with small diameter green saplings and branches less than 2" in diameter. Chip these grouped or bundled
together to provide support for each other. If the material is 2" or larger, feed only one at a time into the Chipper Hopper.

Make sure the DR CHIPPER ATTACHMENT finishes processing material in the Hopper before pushing down the Blade Control
Knob (newer machines) or moving the Blade control Lever to “Disengaged” (older machines) and shutting the engine off.
 Do not force material into the Chipper. If the machine does not chip well, the Chipper Knife may need sharpening or
replacement, or the gap between the Knife and the Wear Plate needs adjusting. See “Removing, Replacing and Adjusting the
Chipper Knife and Wear Plate” in Chapter 4.

Extremely hard knots will not process very well. Use the next branch to be chipped to push any short stubs that have not self-
fed through the Chipper.

Cut the material to be chipped into manageable lengths of no more than five or six feet long before chipping them.
 Overloading the Chipper Hopper will cause the rotor speed to decrease. If you hear the engine RPM of the Field and Brush
Mower decreasing, stop feeding material into the Chipper Hopper until the engine has returned to full speed.
To Free a Jammed Flywheel
Tools Needed:

Two 1/2" Wrenches
Disassemble:
1. Remove any material left in the Chipper Hopper.
Never throw remaining stubs or knots into the chipper hopper; damage will result.
Disengage the blade at the control panel of the field and brush mower. Shut down the engine, wait for all moving parts to come to
a complete stop, remove spark plug wire(s) keeping it away from the spark plug(s) to prevent accidental starting, then wait 5
minutes before performing maintenance procedures or inspection on the chipper.
Never pry against the scroll weldment when removing the deflector or at any other time. This will cause damage to the machine.
