Cutter head swing speed should be
adjusted to a rate that will allow cutter
wheel to pass through stump smoothly.
If jerking, bouncing or significant drops
in engine speed occur, swing rate is too
rapid and must be decreased.
Swing speed should be determined and
adjusted with the controls in the full
open position.
A counter-rotating valve is located
within the hydraulic system to adjust this
speed. Turning the handle clockwise
will open the bypass and slow swing
action. Turning it counter-clockwise
will increase swing rate.
Lower spinning cutter wheel to stump
and make a few light passes at stump to
get a feel for the cutting action.
Gradually increase cutting action and
work away at stump by swinging cutter
wheel left- to-right-to-left through stump
in a sideways motion. Smooth,
effortless cutting lengthens machine life,
minimizes downtime and is more
profitable in the long run.
Continue cutting stump by adjusting
cutting wheel progressively lower until
stump is cut well below ground level.
Raise and swing cutter wheel clear of
stump and position machine closer to
stump for next series of passes. Lower
and continue cutting.
Continue in this manner until stump has
been removed.
Larger stumps may require repositioning
machine to work at best advantages.
