[0075] Embodiment 10

[0076] On the basis of the above embodiments, this embodiment also provides a tractor, including the main upper ladder with the profiling structure as described above.

[0077] This embodiment also provides a tractor. This tractor has a simple structure and reasonable design, makes full use of the limited boarding space, and the plug welding process for the ladder pedal and the connecting brackets on both sides greatly improves the installation accuracy and structural strength.

[0078] The working principle of the present utility model is as follows:

[0079] During the assembly process, the ladder body 1 and the special structure are used to adaptively assemble it with the limited space on the tractor, which is convenient for assembly. At the same time, the special structures of multiple pedals 2 are adapted to the structure of the ladder body 1, which can not only ensure the convenience of assembly, but also ensure the assembly strength and the strength of the entire ladder.

[0080] The entire ladder is fixedly connected to the frame of the tractor by passing the fixing plate 8 through the fuel tank.

[0081] In order to make full use of the space, the angle between the right connecting bracket of the main upper ladder and the vertical plane is 6.4°, which is completely parallel to the right side of the fuel tank. The angle between the left connecting bracket of the main upper ladder and the vertical plane is 1.7°. The left bracket is not parallel to the left side of the fuel tank. Because once it is parallel, all the pedals will not be of the same size and will become larger and larger towards the bottom.

[0082] In addition, the bell mouth of this ladder (that is, the cross-sections of the ladder body 1 and the pedal 2 are both trapezoidal) is in the left-right direction, aiming to make the most of the space and simplify the process at the same time. A 20mm fuel tank expansion gap is left between the right connecting bracket and the fuel tank. The legal requirement for the minimum release gap is 30mm, and a 38mm minimum release gap is left on the left side. The pedal length is increased from 300mm before to 378.5mm at the front and 332mm at the back.
