Finnish truckbrand Sisu is using Mercedes-Benz components that are combined with their own chassis and axles. Here we see a Sisu Polar Hauler heavy transport tractor, ready for 70 ton on the tractor, and good for total GVW’s of 300 ton. The 625 Hp Mercedes OM473 engine is combined with an Eaton Fuller 18+4 gearbox and a dual plate clutch.
Typical Sisu is that the last driven axle can be lifted for less fuel and tyre wear when empty. This way the 8×4 can be driven as a 4×2 tractor.
