information is available within the operator’s manual.
Your CLAAS combine is designed for output and efficiency but this
can only be achieved with the correct operation and maintenance
of the machine.

Overview: 670 -620
Function Description
ACollecting thecrop. The feeder chains (1) accept the crop
from the front attachment and convey
it to the acceleratordrum.

9
Overview: 670 -620
BThreshing the crop.
The stone trap (2) can collect stones and foreign objects.
The accelerator drum (3) accelerates the crop and feeds it to the threshing drum (5).
The preconcave (4) deposits some of the grain, chaff and broken straw on the preparation
floor (10).
The threshing drum (5) threshes the remaining grains.
The threshing concave (6) deposits a large proportion of the grain, chaff and broken straw onto
the preparation floor (10).
The feeder drum (7) feeds the remaining grains and the straw evenly onto the rotors (8).
The lower returns auger (15) transports the parts that are larger than grain into the returns
elevator.
The returns elevatorconveys all parts to the upper returns auger(19).
The upper returns auger (19) conveys all parts to the accelerator drum (3) again.
CSeparating grain.
The rotors (8) convey the straw to the rear and the remaining grains fall through the rotor
concaves on the return pan(9).
The straw is discharged from the machine through the rear hood or is fed into the straw
chopper (17).
DCleaning grain.
The return pan (9) conveys the grains on the preparation floor (10).
The preparation floor (10) transports the crop to the upper sieve (12). There, it is pre-sorted
into grain (below) as well as chaff and broken straw (above).
The fan (11) produces an air blast blowing all lightweight parts (chaff) out of the machine to the
rear.
All grains fall through the upper sieve (12) onto the lower sieve (13). Parts that are larger than
grain fall into the trough of the bottomreturns auger (15).
All grains fall into the grain auger (14) through the lower sieve (13). Parts that are larger than
grain fall into the trough of the bottomreturns auger (15).
E Delivering grain.
The grain auger (14) transports the grains into the grain elevator (20).
The grain elevator (20) transports all grains from the trough of the grain auger (14) into the
grain tank (21).
Grain is stored temporarily in the grain tank (21).
The grain tank unloading tube (22) conveys the grain from the grain tank (21) onto a transport
vehicle.
F Discharging straw.
The chaff spreader fan or the chaff spreader (16) spreads chaff and broken straw evenly
behind the machine.
The straw chopper (17) chops up the straw and conveys it to the radial spreader or the
deflector spreader (18).
The radial spreader or deflector spreader (18) spreads the broken straw evenly behind the
machine.
