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.
