WARNING: To avoid possible injury always wear proper eye and hand protection
when servicing mower blade.
In order for the mower to work properly, and to always obtain a precision cut with lower
HP requirements thus keeping cost down, proper blade maintenance is important.
Blades must be kept sharp, at their original length and corners maintained. A blade
must be replaced if, due to wear or damage, its original shape has been distorted.
