5.
Both blades should be sharpened at the same angle 
as the original cutting edge and must be replaced or 
re-ground at the same time to maintain proper 
balance in the cutting unit. The following precautions 
should be taken when sharpening blades:
a. Do not remove more material than necessary. 
b. Do not heat and pound out a cutting edge. 
c. Do not grind blades to a razor edge. Leave a blunt 
cutting edge approximately 1/16" thick.
d. Always grind cutting edge so end of blade remains 
square to cutting edge and not rounded.
e. Do not sharpen back side of blade.
f. Both blades should weigh the same with not more 
than 1 1/2 oz. difference. Unbalanced blades will 
cause excessive vibration which can damage 
gearbox bearings and create structural cracks.
Refer to Figure 5-7 & Figure 5-8:
6.
Carefully check cutting edges of blades in relation to 
blade carrier rotation to ensure correct blade 
placement. Cutter blades must be installed with 
cutting edge leading in rotation.
Refer to Figure 5-6 on page 42:

Insert blade bolt (#1) through blade (#6), 
dishpan (#4), and flat washer (#2). Secure blade with 
new lock nut (#3) and torque to 450 ft-lbs.
8.
If replacing RC56 Series dishpan (#4) or RC66 
Series blade bar (#10), nut (#7) on gearbox output 
shaft should be torqued to 550 ft-lbs. minimum and 
secured with cotter pin (#8) with both legs bent 
opposite directions around the nut. 
9.
Replace rubber plug (#5).
10. Reconnect main driveline to tractor PTO shaft and 
remove support blocks.
IMPORTANT:  Locknuts can lose their ability to lock 
properly once removed. Always use a new locknut 
when installing blades.
