Remove the blade.

7. 

To replace the blade reverse the above process and tighten 

nut to 100-120 lb ft.
NOTE: Add a small amount of multi-purpose grease to the 

bolt threads to avoid corrosion and galvenic action.

Never mow with dull blades. Blades that 

are bent should be replaced. The cutting blades are 

sharp and can cause severe injury. Wrap the cutting 

surface of the blade with a rag to avoid injury.

1. 

Set the parking brake.

2. 

Clean any debris from the blades. Keep blades sharp and 

free of build up at all times.

3. 

Sharpen blades evenly at the original 30° angle to maintain 

balanced cutting blades. Do not sharpen the underside of 

the blades. Use a electric blade sharpener, a conventional 

electric grinder or a hand file to sharpen the blades.

4. 

Replace any blade with severe nicks or dents that cannot 

be removed by filing.

5. 

Check the balance of the blade after sharpening by placing 

it on a blade balancer. Do not use un-balanced blades.

6. 

If the blade dips on one end, file stock off of the cutting 

surface on that end.
NOTE: Blades that cannot be easily balanced — REPLACE.
