STUDY ON THE METHOD OF GRAIN HARVESTER HOPPER UNLOADING AND FULL HOPPER SIGNALLING USED

The paper presents a study on the method of grain harvester hopper unloading and the full hopper signalling used. The studies were conducted on 42 farms. Of these, it was found that only 9% of the farms were unloaded on the move, in the remaining 91% the harvesters unloaded at standstill. It has been found that on the studied farms harvesters used the following types of full hopper signalling: no automatic signalling (signalling by stopping and opening of the unloading screw) - 8%; with one level of automatic signalling - 6%; with two levels of automatic signalling - 73%; do not use signalling, but go out for unloading at the end of the field after filling the hopper - 13%. Harvesters that had to alert the vehicle for full grain hopper were a total of 62, 84% of which having two levels of automatic signalling, 6% with one level of automatic signalling and 10% without signalling.
