A research on determination of field performance of power transmission and hydraulic system of a domestic production two-wheel drive tractor

In this study, field tests were carried out to determine the performance of the transmission with power-shift mechanism and shuttle unit developed by a domestic tractor company and the electrohydraulic lifter during field work, developed by a domestic tractor company to be used in a domestically produced two-wheel drive tractor. Sensors were used in accordance with the test to be performed during the studies. To measure the traction force, a load pin is positioned on the lower suspension arms of the electrohydraulic lifter. Additionally, a pressure sensor is placed to measure the force coming to the hydraulic middle arm. During the studies, the system temperature with the temperature sensor, the system pressure with the pressure sensor, the input and output speed in the transmission were measured and recorded instantly with the speed sensors. In the studies, it was thought that the values such as draft force and torque obtained by working with chisel, plow, disc harrow, bottom boiler, rotavator and sprayer would play an active role in improving the transmission. Fuel consumption values were also measured while working with the equipment. The received data were evaluated statistically (minimum, maximum, average, standard deviation, coefficient of variation) and deviations between the data were revealed. In line with these deviations, factors affecting transmission performance have been revealed.
