The effect of operational factors on the efficiency of a tractor CASE 7320 and a blade tiller Kverneland CLD 4.7 (operating width 4.7 m) was evaluated using GPS monitoring. As shown by our data operational factors did influence machine performance. The theoretical efficiency given by exploitation characteristics of machines decreased the effect of higher share of non-productive travels within small and irregular plots almost by 25 %. There was a correlation between field speed and travelled unit path and defined classes of size, length and plot shape. The fact that field efficiency depends on plot properties may be used for more accurate planning of machines operations.
