Simply put, a tractor is a large truck (semi-trailer) that is pulled by tools between the front of the vehicle and the trunk

(meaning that the front of the vehicle can detach from the original trunk and pull other trunk, and the trunk can also

detach from the original trunk and be pulled by other trunk).

The difference between fully trailer tractor and semi-trailer tractor

The front of the vehicle with driving capability is called a tractor, while the rear of the vehicle without driving capability is

called a trailer. The trailer is towed by the tractor. There are two ways to connect a tractor and a trailer: the first is that the

front half of the trailer is placed on the traction saddle above the rear section of the tractor, and the bridge behind the

tractor bears a part of the weight of the trailer, which is called a semi-trailer; The second type is that the front end of the

trailer is connected to the rear end of the tractor, which only provides forward pulling force and drags the trailer, but does

not bear the downward weight of the trailer, which is called full trailer.
