Load And Inflation Pressure Effects On Tractive Performance Of Tractor Tires

In this study, effects on tractive performance of four different axle load, three different inflation pressure and four different drawbar pull was determined. The experiments were carried out on concrete surface in drawbar power running track. Slip, drawbar power, dynamic traction ratios and tractive efficiency as a depending on drawbar pull varied from 0.79 % to 23.54 %, from 12.1 kW to 30.1 kW, from 0.213 to 1.156 and from 0.54 to 0.97 respectively. The effects on slip, drawbar power and tractive efficiency of dynamic axle load, inflation pressure and drawbar pull was found significant (P
