Those strong tractors are called "towing tractor".
It used be more common for those vehicles to pull air planes
with a long bar attaching it to the plane, but the latest
model called "Towbar less" has no bars. The size
of the engine of the latest model of Towbar less tractor,
WZ4000, is 515 hp. It is about the same size of the bulldozer,
D375's engine. Towbar less can only go at 5 mph when pulling
an airplane due to the speed limit, however it actually has
capability of running at as fast as 21 mph.

It can move a jumbo jet despite its small body!
Its power is equivalent to that of the bulldozer, D375. |
