Sharpening Metal Blades

Several styles of metal blades are

approved for use on the Brush

Cutter. The 8-tooth blade can be

sharpened during normal

maintenance. The clearing blade

and 80-tooth blade require

professional service.

Before sharpening, CLOSELY

inspect blade for cracks (look at the

bottom of each tooth and the center

mounting hole closely), missing

teeth and bending. If ANY of these

problems are discovered, replace

the blade.

When sharpening a blade, always

remove the same amount of materials from each tooth to maintain balance.

A blade that is not balanced will cause unsafe handling due to vibration and

can result in blade failure.

1. File each tooth at a 30° angle a

specific number of times, e.g.,

four strokes per tooth. Work

your way around the blade until

all teeth are sharp.
