1943 Minneapolis-Moline Industrial Jeep
On display in the WMSTR Expo Area

Little more than a bench seat, a cargo box and four 9.00-20 tires on a 101-inch-wheelbase, 11/2-ton chassis, Minneapolis-Moline built the NTX to serve the Army Air Force's need for an aircraft towing tractor from 1942-'44. Minneapolis-Moline designed the minimal, low-slung body--which looks more like a big louvered oil drum cut in two to cover the tires--to allow the NTX to slip under aircraft wings, while it designed the chassis for maneuverability and traction on improvised landing strips.
For a powertrain, Minneapolis-Moline chose its Model OE 44.5hp 206-cu.in. four-cylinder engine, which was unique in a few ways. First, it used a fully hydraulic valvetrain--that is, the camshaft pushed a plunger, which hydraulically actuated the valves. Second, while the valves were located in the engine block, as with an L-head engine, they were positioned horizontally. The cylinder head was located on the side of the block and the exhaust and intake ports were located on the top of the block. -https://www.hemmings.com/stories/article/the-industrial-jeep-1943-ntx
