Abstract : In large-scale farming ploughing is generally practiced up to 15 deg of slope, the reason of this limitation being not only the safety of operation but also the decreasing layer of tilth and erosion as well. Steeper slopes are generally covered with grass which is either harvested or grazed. The experience indicates that adapted four-wheel drive tractors with conventional tyres can harvest grass under favourable conditions on slopes up to 20 deg. For treatment and harvesting on slopes up to 26 deg special light-weight machines with low pressure tyres are used; these are able to cross some local gradients up to 33 deg by means of adequate manoeuvring.
