PURPOSE:To improve the operational property of a movable agricultural machine whose control handle can be adjusted vertically by enabling its change lever to be moved vertically following the vertical adjustment of the control handle. CONSTITUTION:When the vertical height of the position of a control handle 1 in a movable agricultural machine such as a reaping binder or the like is adjusted, a fixing pin 47 is removed, the handle 1 is revolved using an axis 41 as a fulcrum, and the fixing pin 47 is inserted again in a preset positioning hole 43 and a pinhole 45. In this case, simultaneously a change guide 3 is integratedly moved vertically and a change lever 7 is pushed by this guide 3. This lever 7 is moved vertically using the joint tool 11 of the joint with a change rod 13 as a fulcrum and follows up the vertical movement of the control handle 1. As a result, the relative position of the handle 1 and lever 7 is not varied even if the height of the position of the control handle 1 is adjusted and the operational property of the movable agricultural machine can be maintained well. |
