In this paper,the flexible shaft control mechanism of tractor multi-way valve was briefly introduced.Aiming at the problems of large control force and poor control comfort in the process of tractor operation,the solution of adding transmission mechanism between flexible shaft and multi-way valve was proposed.The control mechanism was only partially modified in the solution.The solution not only had the characteristics of short improvement cycle and high universality,but also saved the manufacturing cost.This paper provides a new idea for optimization of control force.
