e) 

Hold the sequence of buttons for 8 seconds until both the  ‘bale chamber milling direction’ and ‘on’ LED’s 

illuminate. 

f) 

Release buttons and the LED’s should flash alternately. 

g) 

Using the automatic bale chamber speed control button to slow down,  

 

and the manual bale chamber speed control button  to speed up, 

 
h) 

slow the bale chamber down to the point where it just stops. 

 

i) 

Press the ‘off’ button to save the slow speed.  

You have now programmed the electronic controls for the minimum bale chamber rotation speed. 

To programme the electronic controls for the maximum speed repeat the same process again BUT 

Step  c 

should 

have  the  speed  dial  set  to  10  and  in 

Step  g 

you  should  increase  the  bale  chamber  speed  to  the  maximum 

desired. 

Important, 

the  oil  flow  for  the  conveyor  motor  is  prioritised  over  the  oil  flow  to  the  motor  rotating  the  bale 

chamber.    The  speed  of  the  conveyor  should  remain  constant  if  oil  flow  to  the  valve  is  reduced,  as  the  pump 

supplying the oil to the valve is driven from the milling rotor driveline it is important the calibration is undertaken at 

full working PTO speed

The speed of the conveyor can be changed using the thumb screw on the valve block. 
 

General Discharging Instructions 

The speed of rotation of the bale chamber will control the feed rate of the machine, higher rotational speeds will 

result in higher processing speeds and consequently higher power requirements.  The speed of the bale chamber 

is controlled by setting the speed dial on the control desk. 

 

When milling large rectangular bales maximum throughput is achieved if the bale chamber is kept no less than half 

full of material.  The best results are achieved if part bales are loaded into the bale chamber. 
Large round bales can be placed in the tub on end or on their side.  To work out which is the best method for the 

material being chopped try bales in each orientation. 
Avoid dropping a complete round bale into the bale chamber from a high level to prevent shock loading to the mill 

rotor and driveline.   

 

 

 

Ease the bale over the edge of the bale chamber and lower into the tub as gently as possible. 
The evenness of feed and power consumption will vary with the condition of the bale. In general, damp or caked 

straw materials  will require  a higher  power  input than  dry  brittle materials.   Bales with  a moisture content  greater 

than 

20%

 

will result in higher power requirements and take longer to process & could result in blockages. 

The speed of the mill rotor is monitored by  the  electronics,   if the mill rotor requires more  power than the tractor 

driving the machine is able to deliver then, as the rotor speed drops it will reduce or stop the rotation of the bale 

chamber automatically.  Once the mill rotor returns to the operating speed then the rotation of the drum will restart 

and gradually return to the rotation speed set by the control desk. 
The sensitivity of the automatic bale chamber speed control can be altered using the three  modes on the control 

desk.  This  allows  the  power  requirement  of  the  machine  to  be  varied  according  to  the  power  available  from  the 

tractor. 
The mode is switched by repeatedly pressing the automatic bale chamber control button.  

However the optimum setting will vary depending on material moisture content and density. 
As  the  milled  material  builds  up  beneath  the  conveyor  discharge  point  it  may  be  necessary  to  stop  milling  and 

reposition the machine if the material can not be moved away by the loading vehicle.
