Leveling The Mower Deck - Toro TimeCutter MX 3450 74750 Operator's Manual

Removing the Blades
The blades must be replaced if a solid object is hit, if the
blade is out of balance, or the blade is bent. To ensure
optimum performance and continued safety conformance
of the machine, use genuine Toro replacement blades.
Replacement blades made by other manufacturers may result
in non-conformance with safety standards.
Hold the blade end using a rag or thickly-padded glove.
Remove the blade bolt, curved washer, and blade from the
spindle shaft (Figure 50).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 51). Maintain the original angle. The
blade retains its balance if the same amount of material
is removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Figure 52). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the end of
the sail area only (Figure
