The clutch mechanism includes a drive member connected to an engine output shaft, and a clutch plate movable into and out of friction engagement with the drive member. The propelling line includes an input shaft connected to the drive member, a shuttle shift mechanism having at least one oil clutch for establishing and breaking drive transmission from the input shaft, and a change speed mechanism for receiving drive from the shuttle shift mechanism. The PTO line includes a PTO line input shaft connected to the clutch plate of the dry type clutch mechanism.
