Mercedes Benz 443
1 model in this series
Mercedes-Benz MB trac 1300 (series 443): six-cylinder engine rated at 92 kW, built from May 1976 to February 1987, top speed 25 km/h.
The MB trac 1300 of the 443 series was built by Mercedes-Benz at its Gaggenau plant from May 1976 to February 1987 and counts among the long-lived models of the early MB-trac generation. Like the whole line, it follows the system-tractor concept with equal-sized wheels front and rear and a rotating driver's seat for working front- and rear-mounted implements.

The water-cooled six-cylinder engine displaces 5,675 cm³ and produces 125 hp (92 kW) with 392 Nm of torque. Rated speed was initially 2,600 rpm, reduced to 2,500 rpm from March 1982. At an unladen weight of 5,540 kg and a wheelbase of 2,650 mm, the tractor's design top speed is 25 km/h; length and width are 4,680 mm and 2,470 mm, with a height of 2,925 mm.
At 25 km/h the MB trac 1300 stays well within the 60 km/h limit of the T tractor licence class. As on the Unimog, portal axles and standard four-wheel drive provide high ground clearance, allowing use on soft and uneven ground as well.
Since the rated engine speed changed during the production run, it is worth checking the actual state of the injection pump when buying a used example. The tubular frame should be checked for rust at the implement mounting points, and the seat-rotation mechanism for smooth operation. On the hydraulics, check the fittings for leaks. Drivetrain and axle parts are usually still available through Unimog spares suppliers.
