A tractor is a general large truck or semi-trailer that is pulled by tools between the front and the trunk of the vehicle.
This means 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 front vehicle with driving capability is called a tractor,
while the rear 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 to place the front half of the
trailer on the traction saddle above the rear section of the tractor, and the bridge behind the
tractor bears a portion 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 towing the trailer, but does not bear the downward weight
of the trailer, which is called full trailer.
