Inspecting The Blades - Toro 74629 Operator's Manual

Inspecting the Blades

Service Interval: Before each use or daily—Check the
cutting blades.
1. Inspect the cutting edges (Figure 41).
Note: If the edges are not sharp or have nicks, remove
and sharpen the blades; refer to Sharpening the Blades
(page 34).
2. Inspect the blades, especially the curved area (Figure
41).
Note: If you notice any damage, wear, or a slot
forming in this area (item 3 in Figure 41), immediately
install a new blade.

Checking for Bent Blades
Note: The machine must be on a level surface for the
following procedure.
1. Raise the mower deck to the highest height-of-cut
position; also considered the 'transport' position.
2. While wearing thickly padded gloves, or other adequate
hand protection, slowly rotate the blade to be measure
into a position that allows effective measurement of the
distance between the cutting edge and the level surface
the machine is on (Figure 42).
