OPERATORS

2. OPERATING PRINCIPLES
feeding out
The angled paddles help mixing by sweeping the material from end to end.
The placement of the blades ensures the materials reach optimum
size/length, without grinding it down and destroying the all important ‘scratch
factor’ of the forages.
Mixing time will be determined by the required chop length. Follow
procedures contained in this manual or consult your Keenan TMR specialist for
further information.
Root crops can be washed in machines fitted with a ‘beet grid’ by adding
water to the load. When the process is complete, the grid can be opened
and the water drained away.
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 feedout chamber contains an auger which runs the entire length
of the machine.
When mixing/ chopping is complete, the feed out door and tray should be set
in 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 opened partially at first. As soon as 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 to allow an even
feed out rate.
CAUTION:
The VFC door should only be opened when the PTO is
engaged (paddles turning)
