Claims

[Claims for Utility Model Registration] 1. A front wheel transmission device that can switch freely between a standard drive state in which the front wheels are driven at a circumferential speed substantially equal to that of the rear wheels and a high-speed drive state in which the front wheels are driven at a circumferential speed faster than the rear wheels. and a front wheel power output shaft extending forward from a transmission case disposed on the rear wheel side of the tractor and a front wheel power output shaft connected to the front wheels. the front wheel power take-off shaft is connected to the input side of the front wheel transmission, and the front wheel power transmission shaft is connected to the output side of the front wheel transmission; A power transmission structure for a tractor, characterized in that a case is detachably attached to the abdomen of the tractor. 2. The tractor power transmission structure according to claim 1, wherein the drive shaft in the front wheel transmission is disposed in substantially the same horizontal plane as the front wheel power output shaft and the front wheel power transmission shaft.
