An old Swedish tractor towing an old Dutch semi-trailer, carrying an old German excavator. I can dig it. Scale the whole combination down to 1:55 and it would have been my perfect childhood die-cast toy. As a matter of fact, I did have a Siku toy of this Volvo N-series; it was a straight truck with a red cab and yellow cargo bed.
This generation of square-lined Volvo conventionals was introduced in 1973. The letter N (“normal steer”) was used to designate the Volvo trucks and tractors with a nose, while the F (“front steer”, forward control) was used for the cabover models.
The number on the hood’s sides reflects the engine displacement in liters, 7 in this case, followed by the vehicle’s factory GVM rating in metric tons.
Originally the tractor had a 200 hp, turbocharged 7 liter inline-6 diesel engine.
However, it now has a Volvo 10 liter engine, also turbocharged. The biggest engine available in the heavy-duty Volvo conventionals and cabovers back then was a 12 liter inline-6.
Stacks, full fenders and an underride guard complete the chassis.
On the left side a nicely made storage box.
The 1975 semi-trailer has a GVM rating of 34,000 kg (75,000 lbs). Trailer and semi-trailer manufacturer Groenewegen was founded in Rotterdam, the Netherlands, in 1931.
Today’s load, a Weserhütte Hydrowolff HW50. I had never heard of Weserhütte, let alone I ever saw one of their products before.
The fully restored 1972 excavator is powered by a 3-cylinder Deutz engine.
Machinefabriek Werklust was the Dutch Weserhütte importer. Werklust (translation: ambition, vigour, the desire to work hard) was also a renowned manufacturer of all kinds of earth moving equipment; like wheel loaders, powered by a 2-stroke Detroit Diesel. The sound! The sound!
Meanwhile I found a picture of the very same Volvo N12 Siku toy truck I drove as a kid. Imitating all the period-correct engine, gear shifting and air brake sounds, naturally.
