た。(c) Problems to be solved by the invention The work equipment coupling device in the known agricultural vehicle has a bracket for pivoting the front part of the lower link and a bracket for mounting the check chain.
Since it was located further to the rear of the rectangular axle case, the connection point of the lift rod hanging from the lift arm to the lower link was at the rear, reducing the lifting force of the work equipment and reducing the length of the machine including the work equipment. As the temperature increased, the aircraft's ability to maneuver deteriorated.

率良く行なうことができる。 Lift arms 25, 25 are pivotally supported near the rear of the hydraulic case 2a attached to the upper surface of the transmission case 2 by a support shaft 24 so as to be able to tilt up and down.
6, 26 to the left and right lower links 23, 23, and although not shown, a working machine is attached to the upper link and the rear of the lower links 23, 23, and the axle of the rear axle case 1 Case 1
The conventional one is formed into a vertically elongated rectangle as shown in Fig. 5 when viewed from the side, and the lower link 2 is placed behind it.
However, in this proposal, as shown in Figures 2 and 3, the lower part of the rear part is formed into a slope that faces diagonally forward and approaches the rear axle 8, and is attached to the lower part of the axle case 1a near the rear. By providing a space B that is triangular in side view, it is possible to reduce the amount of lubricating oil that is normally injected to a height H corresponding to the axis of the rear axle 8, and furthermore, Since the mounting bracket A of the support shaft 24 that pivots is attached to the axle case 1a within the space B, the support shaft 24 can be provided in the front compared to the conventional method in which the support shaft 24 is attached to the rear mounting bracket of the axle case 1a. Thereby, the attachment position of the lift rod 26 hanging from the lift arm 25 to the lower link 23 can be moved closer to the machine body, and the working machine can be raised and lowered efficiently.

るのを少なくするとができる。 Reference numeral 27 denotes a mounting bracket for a check chain 28 fixed to the rear surface of the midway portion of the axle case 1a, and this mounting position can also be moved forward compared to the conventional one. Reference numeral 30 designates a differential clutch consisting of a fixed clutch portion 32 fitted to the outer periphery of one end of the differential case 31 and a movable clutch portion spline-fitted to the differential shaft 6. Further, since the mounting brackets A and 27 do not protrude from the part of the axle case 1a on the transmission case 2 side in which the gear 9 is housed and from the lower part of the transmission case 2, the mounting brackets A and 27 and the check chain do not protrude from the lower part of the transmission case 2. It is possible to reduce the adhesion of weeds, mud, etc. to the 28 and lower link 23.

とができる。(g) Effect of the invention As mentioned above, the invention supports the rear axle 8 with the transmission case 2 and the rear axle case 1, and supports the working machine with the upper link and the left and right lower links 23,
23, the axle case 1a of the rear axle case 1 is
A space B having a triangular shape in side view is formed at the rear lower part of the axle case 1a by forming a slope with the rear lower part facing diagonally forward and approaching the rear axle 8, and within this space B, the axle case Since the mounting bracket A for the lower link 23 and the mounting bracket 27 for the check chain have been installed on the lower link 23, the front pivot position of the lower link 23 is set in the space B of the axle case 1a, and the connection position of the lift rod 26 is adjusted. The lower part of the rear surface of the axle case 1a is the front part of the axle case 1a. Since the slope of the rear axle 8 is close to the rear axle 8, the capacity of the axle case 1a is reduced, and the amount of lubricating oil to be injected can be reduced.
