I want to buy a tractor with a loan to pull 70 tons of coal and run 450 kilometers a day. I don't know how much horsepower to buy and what brand to buy. I am a novice.
The machines of Dongfeng Tianlong Cummins and Renault are not equipped with 336 horsepower, so Cummins is not suitable for overloading. If you want to overload, you must buy a car with Wei Chai engine, such as Shaanxi Automobile and Ou Man ETX series. Universiade heavy trucks are also good. The rear axle only has a half axle, because you won't overload too much. Both 457 and 485 rear axles can be used, and the gearboxes are basically fast 12.
