When the tractor is stopped, the rotary tiller is grounded and the rotary tiller is actuated and thereafter the tractor is started to travel, then the target gear ratio of the continuously variable transmission is corrected to a speed-reducing side at a prescribed correction ratio until a prescribed distance X or prescribed time T passes from the start of the tractor.
