After the improvement 1302R rubber caterpillar tractor even more will conform to users requirement, the efficiency, the stable line all will have the enhancement. The rubber caterpillar tractor more wheeled and the metal caterpillar tractor has the obvious superiority: 1st, good technical efficiency 2nd, bigger mobility and reliability 3, good operation comfortableness In view of this, the rubber caterpillar tractor future is extremely optimistic. As the agricultural production great nation, Chinas farm machinery manufacturer, should pay attention to the rubber caterpillar tractor in particular the development direction, the positive research, reduces with the international advanced level disparity, the development suits the Chinese use level, the economy purchases the ability, the production and the manufacture level new agricultural tractor. This improvement design then is faces this direction to develop. In this improvement design, has drawn up the tractive characteristic curve, has calculated the entire computer nature heart position and has conducted the man-machine project research, the entire design satisfies the project
