The present disclosure is directed to an agricultural work vehicle including: a vehicle body configured to support an engine; a transmission configured to perform shifting on drive generated by the engine; a braking unit implemented as a hydraulic brake or a mechanical brake, and configured to reduce the travelling speed of the vehicle body and control the deceleration of each of left and right wheels; an operation unit provided in the vehicle body; and a control unit configured to control the transmission and the braking unit; wherein the control unit includes a conjunctive operation module configured to control the braking unit and the forward-reverse clutch so that both the braking rate at which the braking unit reduces the travelling speed of the vehicle body and the drive transmission rate at which the forward-reverse clutch transmits drive are adjusted.

A control apparatus and a control method for a transmission of an agricultural work vehicle are provided, the control apparatus including: a forward/backward clutch of a forward/backward shifting unit that performs forward/backward shifting with respect to drive generated by an engine; and a drive clutch of a drive shifting unit that performs drive shifting with respect to the drive generated by the engine.
