The invention relates to agricultural engineering, in particular to reapers attached to a mechanical power source.Maintaining the right angle between a tractor movement direction and a reaper's load-carrying beam axis during run operation, elimination of bending moment in the carrier frame in operation and transport positions, a quick transfer of the reaper from transport state to operational and vise verse without wheel's rotation, smooth adaptation to relief and elimination of unexpected loads at sudden relief changes is attained in the trailed reaper which comprises a chassis, with the reaper carrier and left and right supporting wheels, an attachment device the chassis and a platform with a cutting apparatus and, according to the invention, is further provided with a turnable wheel mounted on a cantilever arm and protruded forward relative to the cutting apparatus, the supporting wheels are adapted to turn and change wheel leaning angle relative to the vertical axis, wherein the right wheel is adapted to change the angle towards the reaper movement, the chassis is connected with the platform by a rod arranged parallel to the load-carrying beam, and the cantilever arm is connected to the load-carrying beam by a hinge and a spring. |
