The invention relates to agricultural machines with drives of the operating unit 9 that provide continuously variable speed adjustment of the output shaft. The drive has a clutch 4 with an input 34. The input 34 is mechanically and drivingly connected to a drive engine summarizing gear unit 8 has a first input second input 24 and an output 26. The first input 20 is mechanically and drivingly connected to an output 35 of the clutch 4. The output 26 acts to drive the operating unit hydraulic pump 10 is mechanically and drivingly connected to the output 35 of the clutch hydraulic motor 11 is hydraulically connected to the hydraulic pump 10. The motor 11 is mechanically and drivingly connected to the second input 24 of the summarizing gear unit 8. The invention promotes locking reactive power of the unit drive hydraulic circuit and unloading of the clutch 4 and input shaft 12. |
