Sharpening Blades
Blade sharpening procedure:
The Brush Cutter blades are manufactured from Ultra-Kor
tm
alloy, a high strength alloy. When
sharpening this blade material using a side grinder, use extreme caution not to over heat the material.
Allowing the grinder to stop or rest in one spot will cause the material to turn “blue”. Avoid over
heating by keeping the grinder moving at all times. Remember that the rst 1” to 1 1/2” of the blade
and the blade tip is where most of the cutting action takes place. This is point of contact and the
blade bevel must be maintained and kept sharp. If you have the skill to sharpen the blades with a
torch, less heat will be transmitted into the material and will have longer blade life if sharpened in
this manner. Always remove equal amount of blade material from the paired blades. Blades must
be kept within 1/10 of a pound of each other. Always keep blades in the same pairs, (blades across
from each other, as removed from the cutter.
NOTE: Failure to keep the blades sharp will cause multiple problems,
including
1. Hydraulic oil overheating.
2. Extreme blade bolt wear
3. Blade bar fatigue, cracking and total failure
4. Blade fatigue, cracking and total failure
5. Deck fatigue and cracking
6. Increased amount of discharge or debris
7. Poor cut – increased amount of uncut material
Food for Thought: If your blade was an axe head, would you try to cut a tree with it?
Proper Bearing Housing Lubrication
With the cutter sitting level, remove the plug from the side of the bearing housing. Wipe the plug
clean. Oil should run out of the plug hole. If not, add oil. Proper replacement oil is 85-140 weight
gear oil, our part number is T5-LUBE. Make certain the plug is replaced and tightened securely
before operating. If the oil is low , the lower seal should be inspected at once.
