Nemo applications for vehicles to be used on roads came in 1963–1964. Nemo was successfully tested in logging vehicle trailers. In addition to improved off-road performance the system had other benefits; a trailer with a driven front axle could be driven on the lorry platform for transition and set down when the place of loading was reached. When full laden, the Nemo could be used to assist on steep uphills: in case the driver had to gear down, he could switch on the hydraulic drive that was powered directly by the engine, and use clutch and change the gear without risk that the vehicle would stop going. Nemo systems were available for example for Sisu KB-117, M-162 and K-142 logging trucks. Military vehicles In the 1960s the Finnish Defence Forces had 1 800 field cannons. The number of suitable haulers was so small that in case of mobilisation, moving the cannons would have relied on civil lorries. The Nemo system was seen as a solution to improve the mobility. In 1965 one of new Tampella 122 K 60 cannons was equipped with a tandem axle driven by the Nemo transmission system. This was tested with single wheels at first but later double wheels were used. The hauler was a Sisu KB-45 off-road lorry with a hydraulic system mounted on the front end and the oil container installed between the cabin and platform. This was tested in Santahamina during summer 1967, with the KB-45 hauling an SAT-produced trailer. The KB-45 had a weight of 6 490 kg and traction of 48 000 Nm; the trailer weighed 5 220 kg and delivered 30 000 Nm; the combination produced 72 000 Nm. The effect of the tyre size was not considered. Later the system was tested with a Sisu K-141 4×2 together with a field cannon 130 K 54 and Vanaja KK-69 ET 6×6 coupled with a three-axle carriage powered by a separate aggregate-run pump. The test proved even these trucks, not designed for off-road use, could haul heavy cannons in rough terrain using the Nemo system. During the trials it was observed that the trailers even pushed their haulers forward. Equipping all the cannons and most of the haulers with Nemo was conceivable. In 1968 the price of Nemo was 30 000 Finnish marks, divided in half between the hauler and carriage. This price was high compared to a normal truck (50
