The relationship between the belt tightness of walking tractor and power losses was researched through tests and theoretical analysis. The result showed that the loss of frictional power increases when the belt deflection decreases, while the loss of slipping power increases when the belt deflection increases. Taking these two aspects into accoumt, an optimal belt tightness was worked out, that is , when a force is added in the middle of the belt, the deflection of the belt should be within 25 mm～30 mm. In addition, a simple instrument was designed to inspect the belt tightness. Deflections of 121 belts of walking tractors in use were measured and analyzed. It was found that 60 percent of the belt tightness cant meet the requirement,so the adjustment is needed.

The Mingsin walking tractor is not large so it's not expensive to own for farmers with marginal holdings; it's a tractor they understand and identify with. The 15 HP diesel walking tractor comes with additional implements such as anti-wrapping blades and is therefore able to plow, make ridges, and dig trenches for planting. The hand tractor can also be modified to pump water for irrigation by attaching a small pump of 10 meters suction depth, ideal for pumping distances between 30 to 100 meters and best for watering small horticultural gardens.

The agriculture sector in the world is evolving, and at the heart of this transformation is a growing need for advanced farm equipment. Today, we, Mingsin, a leader in agricultural machinery, is tailoring solutions to meet the demands of farmers. With a focus on innovation and efficiency, it is paving the way for a more productive and sustainable farming future.

Agriculture, the backbone of the world economy, is experiencing a transformation, aimed at attracting a vital, often overlooked demographic: young farmers. How do we bridge the gap between the young population and the age-old practice of farming, updating it for the modern era? This is where innovative strategies and companies like Mingsin step in, playing a pivotal role in driving the agriculture sector into a future filled with hope and prosperity.

Some operators believe that it is very simple to repair replacement parts for agricultural machinery, and install the updated parts. In fact, if the new parts are not properly assembled, the power of the agricultural machinery will decrease, the fuel consumption will increase, and the start-up will be difficult; Therefore, pay attention to the following points when purchasing replacement parts.

First, do not substitute agricultural machinery oil for agricultural machinery gear oil. Compared to gear oil, agricultural machinery oil has lower viscosity, and its anti-wear and load resistance properties are also inferior. If agricultural machinery oil is used in place of agricultural machinery gear oil, the transmission gears will not be adequately lubricated, leading to significant wear on the transmission system gears.

The implementation of the purchase subsidy policy is highly efficient, and the level of agricultural machinery and equipment is rapidly increasing. The central government's agricultural machinery purchase subsidy funds reached 21.5 billion yuan, an increase of 2 billion yuan over the previous year, and it was fully implemented at the end of November. The effect of the subsidy policy was significant, which drove the demand for agricultural machinery consumption to heat up. The production and sales of agricultural machinery industry were booming, the total amount of agricultural machinery and equipment was accelerated, and the structure was accelerated. In 2012, the national total agricultural machinery power reached 1 billion kilowatts, which is expected to reach 1.02 billion kilowatts, an increase of 4.3%. Large and medium-sized tractors are expected to reach 4.9 million units, up 11.2% year-on-year; the number of weak rice transplanters and corn combine harvesters is expected to reach 507,000 units and 233,000 units, up 18.7% and 36.1% respectively. The trend of large-scale, double-type and matching of key crops and key links is obvious. The total output value of agricultural machinery industry above designated size is expected to exceed 300 billion yuan, maintaining a growth rate of more than 20% for six consecutive years, and continues to be in a leading position in the machinery industry.

The ideology is contemptuous, and the accidental frequency of agricultural transport vehicles is simple in structure and slow in speed. Most of them are driven on the rural roads where people and vehicles are scarce. Therefore, it is wrong to think that the agricultural transport vehicles do not have to be carefully maintained and operated, and there are problems that can be used for speeding. Overloading and overcrowding are commonplace. However, due to its simple structure, it is determined that its driving performance is not as sensitive, perfect and reliable as a car.

　Triangular tape is widely used in agricultural machinery models. The standardized triangular belt has a trapezoidal cross section and no joints in the whole circle. It is divided into seven types: O-type, A-type, B-type, C-type, D-type, E-type and F-type. The O-to-F profile area is gradually increased. The choice of belt model is based on the power delivered, and there is a lot of knowledge in it.
