The Model “HD-9B” Tractor is an 18,800 pound track-type tractor powered with a 4-cylinder, 2- cycle “DIESEL” Engine. Power from the engine is transmitted through a single plate, over-center type engine clutch to the transmission through a drive shaft universal joint assembly. From the transmission, the power is transmitted to the bevel gear, and from the bevel gear through two multiple disc steering clutches (one on each side of the bevel gear shaft) to the final drives and the track drive sprockets. The transmission provides 6 forward speeds ranging from 1.4 M.P.H. in low gear to 5.7 M.P.H. in high gear and 3 reverse speeds ranging from 1.6 M.P.H. in low reverse to 4.4 M.P.H. in high reverse, under full governed engine speed of 1600 R.P.M. Mechanical “Booster-Type” steering clutch controls, mechanical self energizing brakes, adjustable and wide operator’s seat, and unobstructed view of the front of both tracks assure easy, positive control of the tractor at all times. The tractor is equipped with electric starting and lighting equipment, muffler, full width crankcase guard, front pull hook, bumper, hinged type radiator grille, suction type fan, and 16-inch integral grouser shoes. The truck wheels, track idlers, and support rollers have positive type seals and are protected by guards.
