Abstract

The invention concerns a drive arrangement of a crop conveying and/or processing mechanism of a harvesting machine with an internal combustion engine (25) that is arranged to drive the crop conveying and/or processing mechanism through power transmission elements in a first operating mode in a first direction at a first speed, and a reversible motor (86) that is arranged to drive the crop conveying and/or processing mechanism in a second operating mode at a second speed in a second direction that differs from the first direction. The drive arrangement is also able to be driven in one or both of third and fourth operating modes. In the third operating mode the reversible motor (86) drives the crop conveying and/or processing mechanism in the first direction at a third speed, that is lower than the first speed and in the fourth operating mode the drive of the crop conveying and/or processing mechanism is separated from the internal combustion engine (25) and the reversible motor (86) operates as a brake for the crop conveying and/or processing mechanism.
