A combine harvester for corn is adjusted so that the threshing system maintains the grain and cobs together and there is provided a first sieve to separate the grain and cobs from residue material which is discharged from a rear of the first sieve and a second sieve to separate the grain which passes through the second sieve from the cobs which are discharged from a rear end of the second sieve. The grain is transferred to a clean grain tank and the cobs are conveyed to a tank on a towed cart.
