A self-propelled harvesting machine is provided that has operating devices to take-up and/or process harvested crop, which can be driven by means of a drive belt, that can be driven by a belt pulley about an axis of rotation extending horizontally and transverse to the forward operating direction of the harvesting machine. Two internal combustion engines are provided on the harvesting machine and each are supported on the frame arranged side by side alongside each other relative to the forward operating direction, with crankshafts extending in the forward operating direction. A connecting gearbox is arranged ahead of the internal combustion engines in the forward direction of operation and is connected or can be connected so as to drive with the first crankshaft, the second crankshaft and the belt pulley. The connecting gearbox includes two angle gearboxes that are connected to a transverse shaft arranged in the transverse direction that is connected or may be connected, in turn, with the belt pulley.

An infinitely variable belt-type transmission for an agricultural machine or the like includes drive and driven pulleys and a pair of inversely variable diameter pulleys mounted on a shaft that is shiftable to vary the diameter of the pulleys and consequently the drive ratio of the transmission. The inner halves of the adjacent variable diameter pulleys are drivingly connected through a cam that exerts a force on the inner pulley halves tending to increase the pulley diameters and thereby increase the belt tension in response to an increase in torque transmitted through the transmission, and the shiftable pulley half on at least one of the pulleys is splined to its mating half so that the shifting movement in response to the torque increase results only in axial motion of the shiftable pulley half.
