The invention discloses an agricultural machinery power reversing transmission mechanism capable of automatically switching power take-off, and belongs to the technical field of transmissions. An output shaft; a power take-off shaft; the power reversing mechanism is used for switching the power direction of the output shaft; the electric control power take-off mechanism is used for controlling power transmission of the power take-off shaft; and the hydraulic control system is used for driving the power reversing mechanism and the electric control power take-off mechanism. In the reversing process, automatic forward and backward switching and automatic power output and cut-off can be achieved, the working efficiency is improved, and meanwhile the labor intensity is reduced. 本发明公开了一种取力自动切换的农机动力换向传动机构，属于变速器技术领域，该传动机构包括：输入轴；输出轴；取力轴；动力换向机构，用于切换输出轴的动力方向；电控取力机构，用于控制取力轴的动力传递；液压控制系统，用于驱动动力换向机构和电控取力机构。本发明可以在换向过程中，实现前进后退自动切换，以及动力的自动输出和切断，提高了作业效率，同时降低劳动强度。
