The water-cooled four-cylinder diesel engine of 4,000 cc produces 72 hp (52.9 kW) at 2,350 rpm and 231 Nm of torque. At an unladen weight of 2,660 kilograms, a wheelbase of 2,186 millimetres and a width of 1,930 millimetres, this is a medium-sized all-round tractor with a design top speed of 40 km/h.
At a top speed of 40 km/h, the machine falls into the upper part of driving licence category T. Tractors of this class usually transmit power through a rear three-point linkage to ISO 730 and a standardised power take-off running at 540 or 1,000 rpm, so that mounted implements fit regardless of manufacturer.
When buying a used Hürlimann of this age, it is worth checking the hydraulic pump and PTO clutch for tightness and wear, as well as the condition of the four-wheel-drive hub and steering joints, which are subject to greater loads in mountain work. Corrosion on the wings and cab, and the service history of the clutch, should also be checked. The condition of the cab mounts and door seals is worth checking too, as rust often starts there on tractors used in wet mountain conditions.
