FIELD: technological processes.
SUBSTANCE: invention is related to method for control of rotation frequency of input shaft in power takeoff mechanism. Engine (1) is connected to automatic stepped gear box (9) by automated friction clutch (3). Control of gear box (9), friction clutch (3) and engine (1) is realised with single control unit (45). Control unit (45) adjusts frequency of engine (1) shaft rotation depending on position of control lever (61) by throttling gate and controls operation of gear box (9) depending on position of gear change selector (46). When power takeoff mechanism (32) is connected to engine (1) and gear change selector (46) is put in driving position, frequency of engine (1) shaft rotation is controlled by control device (60). Sliding of friction clutch (3) is controlled by control lever (61) and throttling gate. When equipment driven by power takeoff mechanism (32) approaches limit position, frequency of engine (1) shaft rotation automatically reduces.
EFFECT: makes it possible to increase reliability and resource.
