<p>A tractor having a high power-to-weight ratio (power 100 kw, weight 3500 kg) is obtained by using light-weight components (e.g. made from synthetic resin) for the cab, and by making the wheels (33, 47) smaller than is usual, i.e. with a diameter of 1.3 metres, and from aluminium or other light-weight material. Traction is improved by providing an implement (94, 112) which, in operation, is driven from a power take-off shaft and acts to propel the tractor. </p> |
