NOTE: When sharpening blades take care to maintain
blade balance. Sharpen both blades equally even if one
blade does not need to be sharpened. Check balance by
weighing each blade to make sure they are equal in weight.
CLEANING THE MOWER
Water pressure from a garden hose will remove fresh
clippings from the underside of the mower. Clean mower
after each mowing.
CAUTION:

Your rotary mower has been produced with components
designed for your unit. Although standard V-belts,
bearings, blades, pulleys, etc. may look like parts used
on your rotary mower, while similar in appearance many
are of a different construction and could in some cases
cause a malfunction in the operation of the machine.
