Yes they do, you can see the remains of the trailer last photo left and side ,the trailers are cut down 10 wheel trucks with a draw bar on ,a tractor can haul 15-20 ton of cane.
I referred to tractors, such as that one being repaired at the side of the road in the OP, not tractor-trailers. The former are primarily agricultural vehicles that do not carry loads, the latter are load-carrying commercial vehicles.
