[0002] As an important mechanical equipment in agricultural production, the working efficiency of a tractor is crucial. During the agricultural operation process of the tractor, it is necessary to adjust the counterweight according to different agronomic requirements, so as to maximize the traction efficiency and save fuel. During heavy-load operations, if the number of counterweights is insufficient, the tires are prone to slip during operation, damaging the soil aggregate structure and causing energy waste, increasing the fuel consumption rate. During light-load operations, if there are too many counterweights, it will cause soil compaction, affecting agricultural yields. At the same time, due to the heavy vehicle weight, it also causes excessive fuel consumption. Therefore, during the agricultural production process, it is necessary to adjust the number of tractor counterweights according to agronomic requirements.

[0079] On the basis of the above embodiments, this embodiment further provides a tractor, including the novel front counterweight adjustment system as described above.

By adjusting the distance between the front counterweight and the center of gravity of the whole vehicle, the mass ratio of the front and rear wheels of the tractor can be adjusted, so as to reduce soil compaction and save fuel consumption.
[0081] The working principle of the present utility model is as follows:
[0082] During use, when it is necessary to extend the front counterweight assembly, the telescopic movement of the oil cylinder 4 drives the inner bracket 2 to move, so that the front counterweight assembly extends forward, increasing the proportion of the front axle load;

This system can adjust the distance between the front counterweight and the center of gravity of the whole vehicle through a hydraulic cylinder, so as to adjust the mass ratio of the front and rear wheels of the tractor, so as to reduce soil compaction and save fuel consumption.
[0085] Through the action of the sliding groove and both sides of the inner bracket (i.e., the sliding mandrel) of the present utility model, the counterweight piece can slide, so as to adjust the distribution of the center of mass of the whole vehicle, and thus adjust the mass ratio of the front and rear axles.

By introducing the present utility model, when operating in four-wheel drive, the counterweight piece can extend forward, so as to make full use of the power of the front axle. When two-wheel drive or light-load operation is required, the front counterweight piece contracts, reducing the compaction of the front axle on the soil and making full use of the driving force of the rear axle.
