Nice, Veggie.  Are you really running the engine at 1800 or at 2800 as you originally intended?

Thanks BruceM,
I'm going to start out at 1800 rpm to see how it sounds.
This one may be very happy at 1800....or...maybe not.
It is a simple 20 minute pulley change to step up to 2800 if needed. Although I don't need that much power.
We had some remote site air compressors where I work and they had Kubota Z485's running at 1800 rpm and they seemed fine.
They were systems that ran for extended periods and perhaps the 1800 rpm was to aid in longevity.
All in good fun, if the 1800rpm doesn't sound right I can change it.

As an example of how they sound, here is a video.
At the 27 sec point this fellow gently revs the engine into the 1800 rpm range.

Another example....
They are a fairly tame engine.

Seems plenty smooth at 1800 to me. Nice engine!

I'm looking to buy a Bx25D tractor and went out to a machinery place yesterday to look them over.
The guy opened the engine compartment and there was the cutest tiny little 3 Cyl diesel sitting there. It looked like a mini minor motor only smaller, which it was This was the 3cyl 23 Hp version and even that is compact little thing.

Pitty they are so expensive here. a decent used one goes for $2k+
They seem very compact for the power output.  Fitting a little turbo may help the output and make them even quieter and smoother.
