A drive mechanism for driving a drum, such as a mulcher drum comprises an intermediate shaft coupled to drive the drum by way of a flexible coupling. The flexible coupling may be located on an inside of a hub of the drum. A hydraulic or other motor is coupled to drive the intermediate shaft by a splined coupling. Lubrication of the splined coupling is enhanced by a supply of grease contained in a central passage within the intermediate shaft. The drive mechanism may be direct drive from a hydraulic or other suitable motor. The drive mechanism can be compact and robust against collateral damage resulting from failure of drum support bearings. |
