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 excessive vibrations which lead to premature bearing
failures, bolts coming loose, and overall deterioration of the mower.
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 MR44BC 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 it
s 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.
C.
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.
D.
ENGINE MAINTENANCE
Refer to the engine manual provided in the owner
’
s manual packet.
E.
STORAGE
Turn off the fuel shut off valve (red colored rotating knob) located inline on the fuel hose. The
off
position on the valve is when the red handle lines up with the “O” symbol.
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.
F.

This mower has been designed and built to meet all current EPA regulations. Any modification to
the fuel tank, fuel lines, vapor hose, fuel cap, roll-over / fuel vapor valve, carbon canister
