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
