WARNING: Do not substitute blades or any bolt for the blade retaining bolt.
Company blades and blade retaining bolts are specially made for this application.
Using non original parts can effect the quality of cut and may also cause damage
to the rotary cutter.
DANGER: Proper torque must be used when tightening the blade retaining bolt. If
these safety precautions are not followed, the blade could come off during
operation and be thrown hundreds of feet from the rotary cutter.
