7.6 Washing and chopping root crops
With the machine stopped, add the root material to be washed and chopped. Ensure that there
are no stones or foreign objects hidden in the roots.
1.
Add water at approximately 300 kg (650 lbs.) per tonne of material to be chopped.
Rotate the machine for 1
–2 minutes at 6–8 rpm.
2.
Park the machine on an incline, open the wash gate and allow the water to drain off.
3.
It may be necessary to repeat this if materials being chopped are particularly dirty.
4.
Chop the materials by running the machine at 8+ revs.
For low usage, best results are achieved by chopping sufficient material for two days.
7.7 Feeding out
1.
Ensure that the VFC-door is still closed.
2.
Re-engage the tractor PTO at idle, increasing engine revs to between 1,400 and 1,600
rpm to achieve a paddle running speed of 6
–8 rpm. Allow the TMR to loosen and tumble
for 15-20 seconds.
3.
Slowly open the VFC-door to a maximum of halfway then allow at least one minute
before opening the door fully.
4.
Select a ground speed to feed out at an even rate along the feed area.
5.
When feed out is complete, close the VFC-door, run the machine for 10
–20 seconds to
empty auger chamber, then disengage the PTO before turning out of the shed.
CAUTION
:
Never open VFC-door before engaging PTO
— serious damage may be caused as a
result of sudden load being put on the auger. Disengage the PTO before turning
corners.
