<p>Hydraulic drive which allows a tractor to haul an agricultural implement at reduced speed by using a hydraulic driven gearbox (7) in connection with connection shaft (6). The agricultural implement is driven at variable speed by the combustion engine (19) via drive-link shaft (16). The travelling speed of the tractor is controlled by regulating valve (23) independently of the engine speed.</p> |
