7.8 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 (660 pounds) per ton of material to be chopped.
Rotate the machine for 1
–2 minutes at 6 rpm.
2.
Park the machine on an incline. Open the wash gate and allow the water to drain off.
3.
Repeating this process may be necessary if the materials being chopped are particularly
dirty.
4.
Chop the materials by running the machine at 8+ revs.
7.9 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, no more than halfway. Allow at least 1 minute to pass before
fully opening the door.
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 and run the machine for 10
–20
seconds to empty the auger chamber, then disengage the PTO before turning out of
the shed.
CAUTION:
Never open the VFC-door before engaging the PTO. Serious damage can occur when
a sudden load is put on the auger. Disengage the PTO before turning corners.
