Sisu 7 cyl engine

[Farmer from Finland]

Hey
Today i visited Agcosisupower factory.
Company development chief was keeping a lesson what nad why they are doing today.
Reason to do bigger engine as 84CTA is needed 500HP power for combines and maybe other equipments.Why 7-cyl instead of 6cyl with bigger pots or V8 tec..
Reason:
-7cyl use same common parts as 8,4 CTA.Pistons,crancshafts,rear end,front end are same.Cylinder head is made using 3cyl and 4cyl head.This standard system give big benefit in production.
-7cyl engine is made for Agcos own products and we are going to see those in big combines(MF,Fendt,Cleaner etc.)

Sisu engine factory have largest automation in engine installations,they are able to install 3,4,6 cyl engines using same line using robots without any major changes.

Also Agco is going to invest more to Sisu factory because target is use more and more own engines in own products.

So,seems that US farmers must accept 7 cyl engine also,because Acgo is in future using those.

In a book written by Jim Glastonburry ("Le livre d'or des tracteurs", in french), it is said that Schlüter did make 7 cylinder engines. Does anyone remember it ?

Same question about a variable transmission launched by New Holland at the 2009 Sima show (see below). I think that Schlüter had something similar on the "Euro Trac 1000 CVT".

Continuously variable chain transmission for tractors used in green areas, for specialist crops and livestock up to 115 HP.

This continuously variable transmission concept is based on a variable-speed chain drive and a metal chain with multiple links connecting two variable diameter pulleys.

This pulley and chain variable speed drive controls the continuous variation of a mechanical gear box with planetary gearsets. This concept of continuously variable transmission under load opens up, at a reasonable cost, continuously variable transmission to tractors under 115 horsepower, with optimized efficiency.

Pascal, what you describe is based on the Variomatic, invented by Huub van Doorne, the founder of the nowadays DAF truck factory in Holland. He used it in his small passenger cars with a 600cc engine.

Mitsubishi and Renault are also experimenting, or building CVT transmissions with a friction chain instead of a wide belt, with variable diameter pulleys. I think Audi also did some work on this concept.

==edit: i just found this:
