Blade Servicing
Inspect blades daily. Blades should be free of deep chips, cracks or abnormal bends.
DANGER! Blades should always be replaced in pairs. Blades of different weights may cause serious imbalance which can result in damage to the gearbox. Damage caused by unbalanced blades can make the
machine dangerous to operate, increasing the risk of a broken gearbox lower shaft. Never weld or modify blades. Welding and other modifications such as straightening the blade after it has been bent can severely reduce the strength of the blade, increasing the likelihood that a piece breaks and can be thrown from the machine.
DANGER! DO NOT SHARPEN BLADES. Sharpening blades can reduce the strength of the blade, increasing the likelihood that a piece breaks and can be thrown from the machine. Should the blades become
dull, replace them. Blades should always be replaced in pairs.
Blade Removal
To remove blades for replacement, remove the bolt access cover plate on the deck of cutter near each gearbox. Remove lock nut from blade bolt. It is recommended to change blade bolts and locknuts every time the blades are replaced . Inspect the condition of the blade bolt bushing and contact your dealer if keyway is worn or damaged.
WARNING! AVOID PERSONAL INJURY. Blade and/or blade carrier removal should be done only with the tractor engine shut off, key removed, in neutral, parking brake on, PTO disengaged, PTO input shaft removed, and the cutter blocked in the raised position.
Blade Installation
When installing blades, use new blade bolts and blade nuts. Always replace blades in matched sets. A
WARNING! Use only original equipment blades on this cutter. They are made of special heat treated alloy steel. Substitute blades may not meet specifications and may be dangerous.
