Crop flow adjustments in big baler

Covered in this chapter :
- principles of feeding (packer, packer cutter, rotor cutter)
- double knot principle
-Setup the sensor plates according to the machine type
-Adjust the stuffer
-Explain and adjust the stuffer brake
-Adjust the crop holding fingers to the correct settings
1. Sensor plates
2. Stuffer 
Before loosen the bolts to change the adjustment.
  Place vizegripe on sensor plate (under pre-chamber) to limit the
    sensor plate travel at the right spot.
  Adjust bracket  in the middle of the slotted holes and adjust 
    dimension Z =10mm by lengthening or shortening the linkage 1 .
TIC S’07 : accelerated stuffer (improve top fill)
                   reinforced shuttle pivot arm
                   revised lobe (less
agresive

3. Shuttle feeder               
4. Stuffer brake
It must be possible to clear clutch dog arm away from roller.
The brake spring length is initially set at 35 mm
(1 3/8’’). Check and adjust the brake as follows:
1. With the baler operating at normal speed, check
if the stuffermoves steadily and without abnormal
shocks.
2. Ensure that the stuffer returns and remains in the
home position. Observe the stuffer clutch after
making these adjustments and check if it is
possible to clear clutch dog arm (3) away from
roller (4) by hand.
Final adjustment:
After one hour working:
• the clutchmust not overheat. If it does, reducethe
spring setting by loosening adjusting nuts (2)
 half a turn.
• If the stuffer fork does not remain steady in the
home position, increase the spring setting by
tightening adjusting nuts (2)  half a turn.

5. Crop holding fingers
1. Pull crop holding fingers until rubber stops are touching charge chamber. At
    this point tips of crop holding fingers should be flush with front edge of slots in
    cross beam. If not adjust with shims at rubber stops.
2.Trip stuffer mechanism. The tips of the crop holding fingers should withdraw 0
    to MAX. 10 mm. If not adjust with rod.

3. Check if Y = =/- 10 mm. If not adjust by moving rubber stop.
