Small tractors can achieve good results on iron work

In the operation of squeezing, sowing, cultivating, etc., the small tractor has a large area of ​​damage to the soil structure due to the large area of ​​the rubber tire.

The main reason is that where the tractor is crushed, the soil tightness increases and the tillage layer hardens. Generally, the higher the soil moisture content, the more severe the damage. The adverse consequences are that the roots of the crop are difficult to penetrate and are not good for growth. Second, when the tractor is cultivating and cultivating, the working resistance is large. When it is serious, it must be smashed and the work quality is poor. The problem of replacing the rubber into iron can effectively solve the above problems.

The restructuring of iron is not complicated. The leading edge is made of round steel with a diameter of 24 mm, which reduces the landing width of the edge to about 30 mm. The rear drive is bent into a circle with the same outer diameter as the outer diameter of the tractor with 80×80 angle steel. The single side of the angle is grounded and the plane is flat. Upward; then weld a certain thickness of iron plate at the same distance inside the angle steel, the height does not exceed the outer diameter of the edge; the rear strip is also made of 80×80 angle steel, and the outer end is flush with the outer diameter of the edge. The steel plate welded on the inner side of the angle steel together with the outer end of the strip constitutes the gripping claw along the circumference of the edge, which ensures the tractor has sufficient adhesion.
