It is noted that well-timed shift should increase tractor velocity and a “successful” algorithm should not worsen its usability. Possible criteria were analyzed.tractorsgear shiftelectric-hydraulic and electronic devicesalgorithmsusabilitymeasurementsgear ratioтракторыпереключение передачэлектрогидравлические и электронные аппаратыалгоритмыпотребительские свойстваизмеренияпередаточное отношение
