4.6 Grinding the Top Face of the bedknife
Using the + and - buttons adjust the right hand “Where to want to be” display to the
required angle to be applied to the bedknife.
Now apply a relief grind (reverse angle) to the top face of the bedknife by releasing the
mounting bar and pushing back on the control lever.
APPLY:
Small blades –5° to -9° (eg. greens mowers)
Medium blades –6° to –12° (tees, surrounds and small fairway)
Heavy blades –7° to –15° (large fairway and gang units)
In each case use the lowest angle for very clean conditions, the highest angle for rough
conditions.
(On new bedknives add max 1° to the scratch setting, ie that angle ground at the factory).
When the “Where you are” value equals the desired “Where you want to be” angle it
changes to read “Top”.
Lower the guard.
This example: Setting -7° degrees on top face.
a) Use
+
and
buttons adjust the right hand “Where to want to be” display to -7°.
b) Display reads t-07°:
c) Rotate mounting bar so the left “Where you are” current angle changes from 00º
towards -07º until it indicates TOP.
