1. An agricultural machine comprisingat least one energy producer (19) which comprises an internal combustion engine;
- at least one energy storage device (29) which comprises a battery;
a plurality of wheels for driving the agricultural machine;
a plurality of working units (2, 4, 7, 8,15,16,17) driven by the internal combustion engine; and
at least one electric drive unit (20) associated with the internal combustion engine, wherein the at least one electric drive unit (20) receives energy from the battery, wherein the battery is charged by energy recovered from a braking process of the agricultural machine, and wherein the at least one electric drive unit (20) comprises means for controlling an energy supply of at least some of the working units (2, 4, 7, 8,15,16,17) according to energy requirements of the at least one working unit (2, 4, 7, 8,15,16,17), wherein said at least one electric drive unit is configured to control and compensate variations in rotation speeds of said at least some of the working units when said rotation speeds fall below a predetermined threshold.

Abstract
The agricultural machine has at least one energy producer (19); at least one energy storage device; at least one working unit (2, 4, 7, 8, 15, 16, 17) driven by the at least one energy producer (19) and at least one electric drive unit (20) associated with the at least one energy producer (19). The at least one electric drive unit (20) controls the energy supply of the at least one working unit (2, 4, 7, 8, 15, 16, 17) according to energy requirements of the at least one working unit (2, 4, 7, 8, 15, 16, 17) since it supplies energy to or takes it from the at least one energy storage device (29) as needed.
