Engine power
The first is rated power, also known as rated power, which is an important indicator. It not only reflects the size of the tractor, but also determines the amount of state subsidies (if it is in the subsidy catalogue). The actual power of tractors from different manufacturers with the same rated power will not be the same, because the engine power varies within a certain range. The rated power "calibrated" by the manufacturer may be close to or much smaller than zuihai power. If you can also learn the maximum power from the manufacturer or dealer, it will be helpful to determine which tractor has more actual power or reserve power.
Gearbox type
The technical level of tractors mainly depends on the gearbox. At present, power shift is fashionable, and many tractors are called power shift tractors. In fact, the difference between tractors with high and low power shifts and tractors with semi power shifts (also known as regional or regional power shifts) is quite large. Although it has made great progress over the pure mechanical transmission, the gap between it and the semi power shift is much larger than that between the semi power shift and the full power shift. The technical grade of the gearbox, from low to high, is pure mechanical, high and low power shift, semi power shift, full power shift and stepless transmission. The higher the technical grade of the gearbox, the better the economy of the tractor, which is also the fundamental reason for the higher price of the higher technical grade of the gearbox. However, it should be noted that the transmission with high technical grade may feel relatively slow and "meaty" when shifting gears, which is normal.
Wheelbase
Wheelbase is the horizontal distance between the center lines of the front and rear wheel axles. As long as you ask the manufacturer or dealer, you can get accurate values, or you can use a tape measure with a length of more than 3 meters to measure by yourself. Wheelbase is an advantage for some tractors and a disadvantage for others. The advantage of large wheelbase is that the tractor has large frame, heavy structure weight, good longitudinal stability, and less counterweight can be added during heavy load operation. The problem caused by the large wheelbase is that the weight of the tractor cannot be reduced, the fuel consumption is large, the turning radius is too large, and the tractor is inflexible when operating under light load. Small wheelbase, high-power tractors are generally not suitable for heavy-duty operations with pure traction, such as matching with traction subsoiler and traction rake; However, tractors with large wheelbase and small power are difficult to become "universal tractors" suitable for various light and heavy-duty operations.
