tangled
,
but
easy
to cut
material (canala,
peas,
grain) replace
guards with
stub
guards and
install
a
sickle hold·
down on
every
guard
.
If
material is tough to
cut,
install
stub guards with top guard and adjuster
plate from the MaeDon

section
should be
.020 inch (0.5
mm).
2.

a
low engine
speed
and listen for noise due
to
insufficient
clearance.
Re-adjust
as
necessary by placing a
.020
inch (0.5
mm)
shim
