H.MOWER BLADE REMOVAL, BALANCING & INSTALLATION

Sharp blades can cause bodily injury if not handled properly.

When removing the blade, it is recommended that a block of wood be placed between the blade and the underside of the mower deck. This will allow the removal of the blade without the need to hold the blade by hand.

Always balance the mower blades each time they are sharpened.

Out of balance mower blades cause excess vibrations which lead to premature bearing failures, bolts coming loose, and overall deterioration of the wing mowers.

Always properly tighten the blade bolts to the specified torque. Failure to do so can lead to unwanted loosening of the blade and damage to the blade holding saddle.

The Models E60B, H60T and H60H use the Kunz Engineering Part # (202134) blade bolt. This particular hex head bolt is a 3/8” – 24NF x 7/8” long, grade 5 and it’s proper torque is 35 ft-lbs. The Model C60K uses the Kunz Engineering Part # (202136) blade bolt. This particular hex head bolt is a 1/2” – 20NF x 1.00” long, grade 5 and it’s proper torque is 85 ft-lbs.

To ease in the blade installation process, use the same block of wood and method used during the removal of the blades.
