Cutter Blade Maintenance

WARNING

!

To avoid serious injury or death:  

•

Do not operate cutter with blades that are out-of-balance, 

bent, excessively worn, excessively nicked, or with blade 

bolts that are excessively worn. Such blades can break loose 

at high speeds.

•

Do not attempt to straighten a bent blade or weld on a blade. 

Do not attempt to modify a blade such as hard surfacing, heat 

treating, cold treating, or by any other method. Always 

replace blades with new Land Pride blades to assure safety. 

•

A locknut that has been removed can lose its thread locking 

properties. Reusing a used locknut can result in a thrown 

blade. Always use a new locknut when installing blades. 

Always inspect cutting blades before each use. Make 
certain they are properly installed and are in good working 
condition. Replace any blade that is damaged, worn, bent, 
or excessively nicked. Small nicks can be ground out.

Remove blades and sharpen or replace as follows:

1.

Place tractor gear selector in park, set brakes, shut 
engine off, and remove ignition key.

2. Disconnect front driveline from tractor power take-off 

and secure cutter deck in the up position with solid 
supports before servicing underside of cutter.

3. Inspect cutting blades. Make certain they are 

properly installed and are in good working condition. 
Replace any blade that is damaged, worn, bent, or 
excessively nicked. Small nicks can be ground out.

Refer to Figure 5-2:

4. To remove blades from the cutter, remove access 

cover (#5). 

5. Rotate blade bolt (#1) until aligned with access 

hole (A).

6. Unscrew locknut (#3) to remove cutting blade (#6). 

Blade bolt (#1) is keyed and will not turn freely.

7.

Repeat steps 5 & 6 for the other blade.

8. 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.

IMPORTANT: 

Only replace cutting blades in pairs 

with genuine OEM blades. Replacing single blades 
can result in an out-of-balance condition that will 
contribute to premature bearing wear/breakage and/
or structural cracks in gearbox and/or deck.

Cutter Blade Assembly (Counterclockwise Rotation)

Figure 5-2

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.

9. Carefully check cutting edges of blades in relation to 

blade carrier rotation to ensure correct blade 
placement. Blade rotation is counterclockwise with 
cutting edge leading. Airfoil (lift) must be oriented 
towards the top of the deck.

10. Insert blade bolt (#1) through blade (#6), dish 

pan (#4), and flat washer (#2). Secure blade with a 

new locknut (#3)

 and torque to 450 ft-lb.

11. Repeat step 10 for the other blade.

12. Replace access cover (#5).

13. If replacing dishpan (#4), nut (#7) on gearbox output 

shaft should be torqued to 450 ft-lbs. minimum and 
cotter pin (#8) installed with both legs bent opposite 
directions around the nut.
