FIELD: agriculture.SUBSTANCE: invention relates to agricultural machine building and may be used, in particular, to perform works at relatively small (country and/or farming) fields of mainly flat type. Agricultural bridge contains a unified beam-chassis for replaceable agricultural tools. Beam-chassis brackets are mounted in wheels with no nave box in the form of a rim with a pneumatic machine. Individual onboard rotational drive of every wheel is made in the form of a brace enclosing the upper part of the wheel and bearing rollers in the form of one-cavity hyperboloids on the pneumatic machine, with lower ends of which there are pivotally connected levers with support rollers. At that, the brace can have a mechanism for fixing its position on the beam-chassis.EFFECT: such design allows to simplify and unify the process of making the agricultural two-wheel bridge.2 cl, 1 dwg |
