Lesson plan
Tractor unit
386 sleeper-cab–style commercial 6×4 tractor unit A tractor unit is a characteristically heavy-duty tow vehicle that provides motive power for hauling a towed or trailered load. The largest such vehicles are similar to locomotives, which fall into two categories: heavy- and medium-duty military and commercial rear-wheel-drive semi-tractors that are used for hauling semi-trailers, and very heavy-duty typically off-road-capable, often 6×6, military and commercial tractor units, including ballast tractors. It should not be confused with a tractor-trailer, which is a combination of a tractor unit and semi-trailer. A tractor unit describes only the tractor portion.
