I don't think anybody here argues "against" ETMs.
If they do a good job, prove to be dependable and we do not lose productivity and cleaning ability, we'll be happy to use them.
If you run a generator off the engine to get that extra needed power and heat, you're not that much different than a PTO. So the price better be a lot cheaper and the hassle of running them better be minimal.
As far as over complicated/over engineered TM, this may be a good place to start a good new thread.
How frequently do your TM breaks down and need repair (you or the shop)???!!!
I have seen no real statistics to show that a Cobb or a Judson TMs (or any other of the perceived "simple" TMs) spend less time in the shop than say a
CDS or a
Butler or a
ProChem. I'd love it if any statistics about it will be collected here, that will be a valuable service and info.
I owned three
CDS and I can personally attest that in over 24 years, beside the 400 hour service they rarely ever see the shop.
