Basic components in big baler part3 4- feeding

4- FEEDING
A. Stuffer gearbox
Stuffer gearbox is driven by the LHS halfshaft from the main gearbox.
Goals of the stuffer gearbox :
- activate the stuffer
- drive the knotter gearbox
- drive the hydraulic pump for the density system.

Check the oil level with the glass
B. Stuffer + shearbolt
Is synchronised with plunger, stuffer gearbox and trip mechanism.
Protected with shearbolt and sensor.
The position of the pivot point of the stuffer has changed which delivers a gradual increasing speed of the stuffer and so a better top fill.
The shape of the stuffer bar changed from square to round. Also the dimension increased.
The stuffer teeth have a sawteeth shape which eliminates crop accumulation on the precompression chamber.
The routing of the greasing and sensor wiring loom changed to avoid that the lines are broken during the stuffing.
The material of the stuffer teeth  is hardox
C. Precompression chamber

“Fill flow kit “  improves “top filling” : standard on rotor units, option on packer cutter units
Stuffer trip sensor fingers repositioned (in centre of floor base) – no jamming with stones, giving improved crop flow and higher daily output
D. Crop holding fingers
These are driven from the RHS of the baler and will open when the stuffer is moving. Crop holding fingers and stuffer are mechanically linked. 
E. Sensor plates – Stuffer trip mechanism
Stop can be repositioned according press type
F. Sensor plates – Stuffer trip sensitivity

Controls the size of flakes injected into the bale chamber.
Lever in forth notch (from the rear) to start is ok for most conditions.
G. Stuffer brake

3 springs adjusted to 35 mm
