toward engine to route belt around it. Then

In order to attain the best mowing performance, it is 
important that the blades are well sharpened and 
not damaged. 

Bent or cracked blades or blades with large nicks 
should be replaced. 

Check the blade mounts.

Damaged blades should be replaced when hitting 
obstacles that result in a breakdown. Let the service 
workshop decide whether the blade can be 
repaired/ground or must be discarded.
