The effect of setup of three point linkage on energetic and performance parameters of tractor aggregate

The object of this paper is to analyze the effect of setup of three point linkage on energetic and performance parameters of tractor aggregate. For this purpose were made two series of measurements. The first series was realized with the tractor NewHolland T7050 aggregate with 5-furrow reversible plough plough KUHN HUARD VM 150 5 NS. Data such as engine load, engine revolution, diesel fuel consumption, diesel fuel temperature, were got from CAN Bus network during the measurement. Then were measured following parameters total time of ploughing, dephth of ploughing, time of turning and swath of the tractor aggregate. The specific consumption of diesel fuel and the efficiency of the aggregate were calculated using the aforementioned parameters.The second series of measurements was realized with the tractor Zetor Proxima Plus 115 aggregate with four-furrow plough Kverneland 150 B. During the measurement the data such theoretical and actual speed of the tractor and force in the top link of three point hitch were recorded in the computer. Then were measured following parameters such as main time of ploughing, dephth of ploughing and swath of the tractor aggregate. By the first and second tractor aggregate were approved linear dependence of slip, performance and fuel consumption on the force in top link of three point linkage.
