[0002] As a multifunctional power unit, tractors are widely used in various working conditions. At present, the clutch control systems in the tractor market are all single-mode, controlled by foot or hand, and can only be driven from the front or from the back, which cannot meet user needs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a two-way control clutch device, a two-way operation method and a vehicle in view of the deficiencies in the prior art.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a bidirectionally operated clutch device, comprising: a forward clutch mechanism for installation on the front side of a cab, a reverse clutch mechanism for installation on the rear side of a cab, a transmission mechanism for installation in the cab, and a clutch fork for connecting to a clutch, wherein the forward clutch mechanism and the reverse clutch mechanism are both connected to the clutch fork via the transmission mechanism.
