Mower-Deck Maintenance
Blade Service
To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and
replacement, keep extra blades on hand.
Replace the blades if they hit a solid object, or if the blade is out of balance or bent.
Before Inspecting or Servicing the Blades
1. Park the machine on a level surface, disengage the blade-control switch (PTO), and
engage the parking brake.
2. Shut off the machine, remove the key, and wait for all moving parts to stop before
leaving the operating position.
3. Remove the battery packs from the machine.
Checking for Bent Blades
The machine must be on a level surface for this procedure.
1. Raise the mower deck to the highest height-of-cut position.
2. While wearing thickly padded gloves, or other adequate hand protection, slowly rotate
the blade into a position that allows you to measure the distance between the cutting
edge and the level surface.
3. Measure from the tip of the blade to the level surface.
4. Rotate the same blade 180 degrees so that the opposite blade edge is now in the same
position.
