9.4 Crop roller adjustment
The function of the crop roller and fingers is to hold down and spread out the baling
material in order to achieve a smooth crop flow into the pick-up unit. The crop roller
height should be adjusted, by engaging the chain links in the keyhole slots, so that the
stops do not rest on the rubber bumpers as shown. Once this initial height is set, it is
then self adjusting depending on crop conditions. Ensure linch pins are used to secure
chain links together. Once adjusted, the crop roller should run along the top of the
swath. In lighter conditions it should be adjusted as low as possible, but still ensure that
the stops do not rest on the rubber bumpers.
9.5 Unblocking system
The machine is equipped with an unblock system. In the case of a blockage in the
feeding channel, the PTO overload clutch will disengage and a loud clicking noise will
be heard. Once this sound is heard, immediately turn off the tractor PTO.
The channel floor can then be lowered by holding the floor diverter (button 7) and
operating the pick-up spool lever in the down direction.
Then restart the tractor PTO at a slow speed, increasing speed slowly up to normal
working speed. Any lumps of material can now be easily transported into the bale
chamber. When the blockage is cleared the floor can be raised again by holding the
floor button and operating the pick-up spool lever in the up direction. This works the
same in MAN or AUTO mode. (See ‘Unblock floor operation’). Baling can then resume
as normal.
