Claims

[Scope of Claim for Utility Model Registration] Inside the rear case 2 connected to the rear of the transmission case 1, there is a propeller shaft 3 protruding from inside the transmission case 1, a differential device 4 receiving input transmission from the propeller shaft 3, and the rear case. In an agricultural tractor in which a PTO shaft 5 protruding rearward at a substantially central position in the width direction is arranged in series in the front and rear, the propeller shaft 3 and the propeller shaft 3 in the width direction of the rear case
is arranged eccentrically on one side of the left and right sides with respect to the PTO shaft 5, and supports the rear end of the propeller shaft 3 at a position spaced from the front end of the rear case 2, and the front and rear of the rear case 2. A second support wall 8 that supports the front end of the PTO shaft 5 is provided upright on the inner bottom surface of the rear case 2 at a position overlapping the ring gear 7 of the differential device 4 in the direction, and a second support wall 8 is provided on the inner bottom surface of the rear case 2. The support wall 6 supports the clutch driven shaft 9.
A live PTO transmission shaft mechanism 11 that includes a PTO clutch 10 installed in the rear case 2 on the front side of the rear case 2 and that transmits power to the PTO shaft 5 is located at an upper position in the rear case 2, and on the front side of the first support wall 6. An agricultural tractor characterized in that a ground PTO transmission shaft 13 is provided at a lower position in the rear case 2, which is rotatably driven by a ground PTO take-off gear 12 fixedly installed on the propeller shaft 3 and transmits the transmission to the PTO shaft 5. .
