No, the model 11540 was the first to use this water cooled SLH engine. Of the 11540 one or two prototypes ran in Ireland, right before the 6 series was introduced under the trade name Forterra (11641) There have been rumors (from Perkins minded England offcourse !!) that a Perkins engine was to be used, but that was a false rumor.
The engine contract ends in 2005 (maybe 2006) when a new emission regulation (Tier/Euro 3) comes in. The hottest rumor is, that this will be the time when the production-ready prototype of Zetor's own UR3 6 cylinder will come into production.... Just look at this point: they say the Forterra rear end is capable of 135-140 hp. The rear end and clutch were reinforced for the new 11441 and 11741 models. All they had to do is change the chip of the motor management to get 1 or 2 extra models...
I guess HTC is just selling this one 6 cyl model, to comply to the engine contract with SLH. When teh contract is expired, i suppose they want to take full boost with their own engine. There has never been much animo for the 11641 and 11741 models, there are loads more 114 models sold than 117...
But rumors about this Zetor 6 pot have been around for a long, long time....
Probleby zetor has not the money, and to little pieces to make the investment to come to euro 4 So with in some years they buy the SLH-deutz or the SLH-indian engine for the whole range. Or zetor will be sold, it now core bisnuss for the owner from the moment
Euro 3 is achieved by Tatra in their V8 12.6 liter air cooled truck engine, with a Motorpal mechanical fuel pump, like the one used on Zetors.
Deutz stopped the development of air cooled engines, because they thought it would be too expensive to achieve Euro 3 or 4 with an air cooled engine, due to the hotter combustion temperatures.
Knowledge and experience is available at both Zetor and Motorpal, and with ongoing development, it is just a matter of a next step, like the many steps they have done before. It would be a totally different story if a brand new engine series had to be developed.
HTC has a quite different business approach than CNH or Agco. They want to grow in one organisation, one step at a time, not throwing years of development away when they merge two companies together and need to drop one line or the other. At the moment, Zetor is taking built-to-specification parts from subcontractors, and doing mostly just R&D, assembly and marketing. This system enables them to buy from the best and cheapest subcontractor, where CNH and Agco are bound to their own manufacturing and machining, mostly workers that arent very motivated to do their work because they depend on many more variables than an employee in a company that takes work from more than just a tractor manufacturer. IF they dont have work from a tractor manufacturer because the tractor market collapses, they can take some more work from other sectors of business.
You can see that everywhere in the market: Fro example Hiab truckloading cranes just do development and assembly, and get their parts, built to their specification, from a subcontractor like Tosec, where i worked as a calculator.
To get a subcontractor do the machining or whatever capital intensive work, is the way to go int he business: If you do it on your own, you loose money because the mills are standing still (loss) when the market for your product collapses.
But the subcontractor, they can take work from manufacturers of industrial stuff, so the subcontractor IS able to keep the mills rolling when the tractor market collises.
That's where companies like CNH is running stuck: Their employees and CNC mills and lathes are doing nothing when there arent any tractor orders. Unused machines is the biggest loss.
....Does anyone get a clear view of what i was -trying- to tell ??
