BLADES
Blade and Blade Carriers
Inspect blades daily. Blades should be free of deep chips, cracks or abnormal bends.
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.
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.
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 1-5/8"
socket can be used to torque blade bolts to 600 ft-lbs. dry assembly. You will need at least 3 feet of leverage to
be able to do this. Check blade bolt torque after the first 10 hours of operation.
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.
Re-tighten blade bolts daily. Access holes are provided on the deck of the cutter to facilitate this. After
installing new blades or blade bolts ensure that blades are free swinging and that there is 1" to 1-1/2" (25-38
mm) of free up and down motion at the tip of the blade. Mnt-R-0004 str
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 fail in a hazardous manner that
could cause injury.
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY
CAUSE SERIOUS INJURY FROM THROWN BLADES.

Blade Carrier Removal
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable two-jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is
not available use a long bar inserted through the bolt access hole, striking the long bar with a sledge hammer.
Rotate blade carrier 180° and repeat process until the blade carrier is loosened.
