Abstract

A telescopic reel for an agricultural machine includes at least one side module being telescopic relative to a central module for causing the reel to switch from a retracted position to an extended position. A second crosspiece of the side module is adapted to enter into a cavity of a first crosspiece of the central module when the reel is in the retracted position, and is adapted to be extended when the reel is in the extended position. The first crosspiece and the second crosspiece are provided with a crop lifting system. The lifting system includes a connection for connecting lifts to at least one intersection element of the reel so that the lifts can slide along the second crosspiece of the side module. The lifts are brought close to each other when the reel is in the retracted position and the lifts are positioned relative to each other and to the at least one intersection element, at a distance substantially matching that of connection, when the reel is in the extended position.

Abstract

A harvesting header for a combine harvester comprises a central header section and two lateral header sections hinged to and arranged to rotate relative to the central section for assuming a working configuration, in which the three header sections are mutually horizontally aligned, and a transport configuration, in which the lateral header sections overlap the central section. The header sections are provided with a support frame and a cutting bar associated with the support frame by a hydraulic suspension and comprising a blade having substantially trapezoid-shaped knives capable of to-and-fro movement by a motor-driven control member. The header sections also include a pick-up reel supported on the support frame by means of swivel arms, a transport belt conveyor arranged downstream of the cutting bar and configured to feed the material cut by the cutting bar downstream of the harvesting header toward a rear part of the harvesting header.
