Transmission Characteristics and Experiment of Hydraulic–Mechanical Transmission of Cotton Picker

Agriculture
To overcome the issue of unstable speed output encountered by cotton pickers operating in harsh environments and subject to frequent external load fluctuations, a hydraulic–mechanical transmission (HMT) for cotton pickers is proposed in this study. By analyzing the driving system of the cotton picker, a Lavira-based HMT scheme is developed.
