PROBLEM TO BE SOLVED: To provide a combined harvester capable of improving steering performance on a weld field and a soft ground, and facilitating fine adjustment of the steering direction in conducting fine adjustment of the turning direction at the time of arranging a row. SOLUTION: In this combined harvester, a hydraulic type continuously variable transmission for traveling and a hydraulic type continuously variable transmission mechanism for turning are connected to a travel part through a differential mechanism. A steering wheel is provided to operate the hydraulic type continuously variable transmission mechanism for turning. A fit steering device is provided on the right side of the steering wheel for fine adjustment of the turning direction. The fit steering device can be operated by finger tips as the steering wheel is gripped by hand. COPYRIGHT: (C)2006,JPO&NCIPI
