Bedknife Top Angle Indicator and Mount
Toro Part Numbers: 131−6828 and 131−6829
Because the top grind angle on bedknives is critical for
edge retention, and therefore after− cut appearance,
Toro has developed these service tools for accurately
measuring the top grind angle on all bedknives.
Since there can be variations in the mounting surface of
the bedbar, it is necessary to grind the bedknife after
installing it to the bedbar.
1. Place the angle indicator on the bottom side of the
bedknife with the digital display facing you as shown
(Fig. 11).
2. Press the Alt Zero button on the angle indicator.
3. Remove the angle indicator and place the angle−in-
dicator mount on the edge of the bedknife so the face of
the magnet is flat against the top of the bedknife
(Fig. 12).
4. Place the angle indicator on the mount with the digital
display facing you as shown (Fig. 12). The angle dis-
played on the indicator is the current bedknife top angle.
