EPA approval??

Good looking tractor at a good price. There are precious few parts for this tractor in the USA. Terraplane imported a handfull of these several years ago, and there may be a few more that have slipped in under the radar (probably has an engine manufacture date of 1997) . These low quantities mean parts will be very scarce and will be slow to get from China. We can probably get them from China special order shipped in our containers of 25 and 35HP EPA certifed tractors. The Farm Pro/foton will give you air conditioning in addition to the heat, but the features of this KAMA are impressive for the money. Too bad we can't import these....

( It wasn’t that we couldn’t get the emissions down (we had to add a turbo to do it) we just couldn’t get the engines to run long enough to finish the 5000 hour run time requirement. 2500 to 3000 hours was all we could get before they puked.

What does THIS mean? It seems to me that our Chinese made tractors are going to die in 2000-3000 hours... That's NOT a comforting thing to know...

You are in no danger of being prosecuted. The dealer is the one breaking the law. It is not illegal to own a non EPA compliant engine it is just illegal to import it.

Man, that looks like some kinda tractor for the money! Great features too. Makes my KAMA look spartan.
Chip....
You really should try to get these. /forums/images/graemlins/grin.gif I'd consider trading mine in for one of them.

I would say that to meet an EPA emissions specification, they had to increase the combustion efficiency and temperature to more fully combust the fuel burned and reduce the percentage of harmfull emissions. Basically they needed more bang out of each firing cycle with the same ammount of fuel. You could do this by increasing the compression ratio but that requires some fairly major internal mods. The same thing can be accomplished without internal mods through externally raising the compression ratio(turbo or blower) and adjusting the fuel deliver(different injectors and pump adjustment). I am guessing they went this route as it would have been the easiest/cheapest to accomplish on a per engine basis without an entire engine re-design.

It sounds like The basic engine design probably wasn't designed to handle the added stresses this imposed(higher chamber pressures and temps).

Used as designed, the engine should last a long time, it will just have a dirtier exhaust(also as designed).

Has anyone (besides obviously Buck) put one on a dyno to see if real output equals nameplate hp?

does anyone know if china is going to comply? If we can't get these types of tractors in the USA (can't import per EPA)US dealers not selling in 06, will our market share of the chinese tractor hurt china enough that they will comply?

Bingo Ron, your right on the nose. Also the engines had to run at rated RPM during the test. So basically wide open for 208 days straight.

That was just to meet Teir l. Teir ll requirements were going to be impossible to achieve. I talked with an engineer at Yanmar and even they were struggling to meet Teir ll in some hp classes. I asked him about Teir lll and he said at that level it will be impossible to achieve without a computer management system in conjunction with milti firing electronically controlled injection pumps. I don’t see China getting to that level in my lifetime they will have to outsource engines.
