Checking the Top Grind Angle
The angle that you use to grind your bedknives is
very important.
Use the angle indicator (Toro Part No. 131-6828) and
the angle-indicator mount (Toro Part No. 131-6829) to
check the angle that your grinder produces and then
correct for any grinder inaccuracy.
1. Place the angle indicator on the bottom side of
the bedknife as shown in
Figure 25 .

3. Place the angle-indicator mount on the edge
of the bedknife so that the edge of the magnet
mates with the edge of the bedknife (
Figure 26 ).
Note:
The digital display should be visible from
the same side during this step as it was in step 1 .
