Sharpening Metal Blades

Several styles of metal blades are 

approved for use on the 

Brushcutter. 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.

2.

DO NOT file the ‘gullet’ (radius) 

of the tooth with the flat file. The 

radius must remain. A sharp 

corner will lead to a crack and 

blade failure.

If an electric grinder is used, use care not to overheat teeth, do not 
allow tips/tooth to glow red or turn blue. DO NOT place blade in 
cooling water. This will change the temper of the blade and could 
result in blade failure.
