によりトラクターの前後方向の傾きを調整して組立てて
いる。However, if these frames of the same size are assembled on tractors of different sizes for one use, each size of tractor uses tires of different diameters, so the front and back of the completed tractor will be different. The tilt will be out of order. In other words, if the diameter of the rear wheels is too large compared to the diameter of the front wheels, the rear of the tractor will lift up and the entire tractor will lean forward. Therefore, when actually manufacturing a tractor, the longitudinal inclination of the tractor is adjusted and assembled using several different methods.

モ成としたものである。The present invention makes it possible to extremely easily adjust the longitudinal direction when assembling the tractor, and a knitted joint member is provided at the rear end of a pair of left and right frames in the longitudinal direction, and the joint member is provided with a knitted joint member. A desired number of three or more bolt holes are formed at equal intervals on the bolt, a joining member corresponding to the joining member is provided at the front end of the rear axle case, and bolt holes formed in the joining member and the joining member are provided in the front end of the rear axle case. By shifting the comrades downwards and attaching them with bolts, you can adjust the lower positional relationship between the rear wheel attached to the rear axle case and the frame, thereby adjusting the longitudinal inclination of the agricultural tractor. Agricultural tractor frame and frame 1
- The lower width of Yamakawa Torakuku's frame is designed so that it gradually becomes thicker from the middle of the frame to the rear end.
It is a complete set.

’ｌである。To explain this with reference to the drawings, reference numeral 1 denotes a frame extending in the front-rear direction, and several front wheels 2 are mounted in front. On the rear side of the frame 1, the width under L is gradually increased toward the rear end, and the joining member 3 is welded to the rear end. The joining member 3 has -
1. Pole i, which penetrated in the front and back direction with a distance of q.
A desired number of holes 4, 4, etc. are formed at least three. Reference numeral 5 designates a rear axle case 11411, which is made of cast iron, and a joining member 6 corresponding to the joining member 3 is welded to the front end of the rear axle case 5. The joining member 6 has the bolt hole 4.4.

After this, the joining surfaces 10 of the joining members 3 and 6 are welded and shaped. However, the joining r? 1; When connecting the material 3 and the joining member 6, the frame 1 and the rear axle are aligned by sequentially shifting the alignment of the bolt holes 4.4 and bolt holes 7.7. In case 5, adjust the relationship between the two. A transmission shaft 11 is provided on the left and right sides of the rear axle case 5, and a rear wheel 12 is provided at the tip of the transmission shaft 11. 1

トラクターの前後方向の（ｌｉきに狂か生じない。However, in the present invention, a set of joint members 3 are provided at the rear ends of the left and right pairs of frames 1 in the front-rear direction, and the joint members 3 are provided with three hole holes 4 at equal intervals of 1[/I]. A desired number of bolt holes are formed, and a joint member 6 corresponding to the joint member 3 is provided at the front end of the rear center shaft case 5, and the bolt holes formed in the joint member 3 and the joint member 6 are sequentially shifted vertically to form a hole. This agricultural tractor adjusts the positional relationship between the rear wheel 12 located on the rear axle case 5 and the frame 1 by attaching it with I.8, thereby adjusting the longitudinal inclination of the agricultural tractor □-. , and frame 1's width is Yamakawa Torakku's frame 1, which is formed so that it gradually widens from the middle of frame 1 to the rear end, so a. Frame 1 of the same size. Even if you use tires with different inner diameters,
The tractor's longitudinal direction (li) will not be distorted.
