The slippage and traction force is measured under several modes of driving, and the result is the evaluation of traction force under the slippage that normally occurs during regular farm work (about 15%). The results are based on measurements conducted on July 22, 2015. Measurements are done by Research Institute of Agricultural Engineering, p.r.i....“The field tests have so far demonstrated the clear advantages of PneuTrac over conventional tyre designs and confirmed previously released lab test results. The most important PneuTrac benefits are a larger footprint, greater tractive force and also higher lateral stability at a lower inflation pressure when compared with the standard tyre,” Mabin added.
