Adjustment of the knotter in big baler part4 5. Adjustments

Do not adjust the baler without having seen the performance in the field
Only adjust if really necessary or after maintenance/renewal
 
A.Twine quality

Take a half of meter twine and start untwisting the twine.
A good quality twine will have 15 to 30 windings, a bad quality twine 8 or less.
Q-twine is produced by Cotesi S.A., europe’s largest and most advanced twine producer
They are ISI 9000 accredited.
Ferric-oxide colour (rust colour) offers enhanced U.V. protection and is long lasting when exposed to sunlight.
Q-TWINE has ‘Easy-Feed’ spools to ensure trouble-free knotting from the start


B.Twine tension
Practical adjustment :
-Completely loosen the twine tensioners.
-Pull the twine (in the bale chamber or after the tucker arm) towards you.
-Increase twine tension until the slacker arm comes down and stays down without pulling twine from the twineboxes.
During the formation of a bale the slacker arm (and indicator flags) are in the completely down position. If it raises, increase twine tension

C.Knotter Bill hook
Practical adjustment :
-Untighten the billhook spring nut until the bill hook opens.
-Hold the billhook tongue open with your finger.
-Tighten the nut until the billhook tongue just closes. Do not overtighten.
D.Stripper arm
Practical adjustment :
-A force of 40 to 60 N should be necessary to move the stripper arm flange over the heel of the bill hook.
-When adjusted correctly, the notch of the stripper arm will travel beyond the end of the bill hook with a minimum distance X = 15 mm
-Adjusting : bending
small adjustments : on stack.
