Note: If the brake stud is adjusted to the end of the slot and the brake stud clearance is under
1/2” then it is time to replace the belt.
CAUTION: If brake stud is not set in correct position, under-braking or over-braking may
occur. If over-braking occurs, premature belt failure or a possible fire could occur due to
excessive friction and overheating.
G. MOWER BLADE REMOVAL, BALANCING & INSTALLATION
CAUTION: 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.
CAUTION: Always balance the mower blades each time they are sharpened.
Out of balance mower blades cause excessive vibrations which lead to premature bearing
failures, bolts coming loose, and overall deterioration of the mower.
CAUTION: 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 MR44B and MR44V use the Kunz Engineering Part # (202141) blade bolt. This
particular hex head bolt is a 3/4” – 16NF x 1-1/4” long, grade 5 and its proper torque is 300 ft-lbs.
To ease in the blade installation process, use the same block of wood and method used during
the removal of the blades.
H. LUBRICATION
There are three lubrication points on the rough cut mower -- one spring-loaded idler pivot and
two caster wheel pivots. Lubricate at approximately 10 hr. intervals or more often as required in
dusty conditions.
I. STORAGE
Turn off fuel shut off valve which is located on the underside of the gas tank. If the mower is
stored outside, the engine should be covered to prevent water from getting inside the engine
during heavy rainstorms. See the Engine Manual for additional information.
