Designation, Operation, Function
12
The adapter of the corn head receives drive from the passing axle of the feeding
house of the combine through universal drive shaft or chain shaft coupling. The
shaft driven by the combine drives the snapping units directly through a chain drive.
The snapping units use chain shaft coupling to transmit drive (to each other).
The adapter cannot be overburdened thanks to the security switch built into every
snapping unit, the switches are built into the passing axles.
The drive of gathering auger is chain transmission as. In the 6 and 8-row machines
the auger receives drive from the passing axel of the outer left snapping unit. In the
12 row machines the auger receives drive from both end of the adapter. The worm-
gearing is protected from overburden. It is supplied with a separate security switch
built in the sprocket on the auger axle. As the adapter in itself is non-functional, its
operation, fitting to the combine and the accomplishment of the necessary adjust-
ments -similar to the grain cutting-table -happens in the operator box of the com-
bine.
After putting into operation the adapter is suitable for harvesting which you should
start by taking into consideration the followings:
1. After a short sound signal start the engine of the combine!
2. After checking that no one is close to the adapter, lower it down in a way that
the sliding thrust of the snapping unit should be at about 8-15 cms from the
ground - in case of appropriate adjustment the divider points touch the ground
– and then turn on the adapter drive!
WARNING!
It is only allowed to drive the corn header in the specified har-
vesting position.
3. Start the harvesting in the sowing direction of the corn!
4. Drive the adapter with the recommended harvesting velocity (7-8 km) in the
row!
Emergency stop:
During harvesting unexpected events may take place when you have to stop the
adapter suddenly (shut off the drive and stop the machine).
