MOWER BLADE MAINTENANCE

Check the mower blades daily. They are the key to power efficiency and well-groomed turf. Keep them sharp -- a dull
blade will tear rather than cut the grass, leaving a brown ragged top on the grass within a few hours. A dull blade also
requires more power. Replace any blade that is bent, cracked or broken.
Never attempt to straighten a bent blade by heating, or weld a cracked or broken blade as the blade may break and
cause serious injury. Replace worn or damaged blades.
Never work with blades while key is in the ignition switch. Turn key to "OFF" position, remove the battery packs
from the machine. Block up mower when you must work under it. Wear gloves when handling blades. Always check
for blade damage if mower strikes a rock, branch or other foreign objects!
Touch-up sharpening can be done with a file. Check the blades for balance following grinding. A commercial
balancing tool is available through most hardware supply stores, or balancing can be done by placing the blade on
an inverted line punch or 12.7mm (1/2") bolt. Blade should not lean or tilt. While spinning the blade slowly, it should
not wobble. If blade is out of balance, true it up before reinstalling. Lay the blade on a flat surface and check for
distortion. Replace any distorted blade.
• The blade sail (curved part) must be pointing upward toward the inside of the deck to ensure proper cutting.
• When mounting blades, rotate them after installation to ensure blade tips do not touch each other or sides of the
mower.
• Failure to correctly torque the bolt may result in the loss of the blade, which can cause serious injury.
• Mower blades are sharp and can cut. Wear gloves and use extra caution when servicing them.
7.1.1 REPLACE THE BLADE
See figure 17
1. Stop the motor, remove the start key, and set the parking brake.
2. Raise the height of the cutting deck to its highest position to allow access to blades.
If necessary, raise the mower by placing on a lift or using a jack and jack stands, or remove the cutting deck as
described in the previous section to gain access to the blades.
