5.6 Feeding Out
During mixing, the mixing chamber is separated from the feed out chamber by
a Variable Feed Control (VFC) or guillotine door, thus ensuring complete mixing.
The feed out chamber contains an auger which runs the entire length of the
machine.
When chopping/mixing is complete, the feed out tray should be set to the
required position, and the VFC door dropped, allowing the material to be swept
up by the paddles and pushed onto the auger – see figure 2. The VFC door
should be partially opened at first, ¼ ways, and when feed is seen discharging
then 15-20 seconds should be allowed before opening the VFC door fully. Door
position and ground speed should be set/used to allow an even feed out rate.
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 maximum of ½ way then allow at least 1
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 shed.
CAUTION:
The VFC door should only be opened or closed when
the PTO is engaged (paddles turning) when material is
in the machine.
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.
