Pics when you get them! )</font>

The mower that I bought can still be seen for now in the eBay Auction where I first found it (I ended up getting it for "a hundie" less than the Buy it Now price). It's a wee bit "cosmetically challenged", but appears to be mechanically sound.

Wayne still has a pic of the YM1510 on his website. I don't think he'll mind if I put up a link to it here.

Excellent!
Hope that mid mower works out for you. I'm jealous. I'd love to get one for my 'bota. One day /forums/images/graemlins/grin.gif

I have your tractor on my dyno and it ran 19.9 hp. So I stand corrected it wasn’t the 21 I said it was or manual said it was.

Re: [url]www.ustrading.net[/url]

Thanks for the update. Did you get one of them in then? Very interesting for sure, especially since all the published data for the engine listed it at so much more. At least what I was able to find.

I'm assuming that is PTO hp? How many hours are on the tractor you're testing?

Thanks again for the information. Nice to get data from an actual test rather than the manufacturers sales/engineering brochures.

It does strike me as odd it was that low though. Is it a straight gear tractor? I guess 6% isn't all that much to be off. I would have thought for sure it would be more though since the only US models I could figure were using the same engine listed PTO HP so much higher.

Do you think the US models that used this same engine (I believe the L2900, maybe the L2800) are overated this much also? I think I read somewhere in the literature for the L2900 it was "rated" for 24 PTO HP. In that case 18% is a significantly higher margin of error than I would have thought acceptable. Although I hear guys talking about the Nebraska Test centers numbers all the time and some of the claims by manufacturers turn out to be pretty bad.

One more question, you said the 21HP is what the manual claimed? Does that mean you have a copy of it?

Re: [url]www.ustrading.net[/url]

It was PTO hp yes, the tractor had 670 hours and the compression was within factory specs. I also have a spare engine coming so I will test that when it arrives. The tractor was sold by another dealer who also claimed the KW business. Except this customer was using it for a Gen set. He couldn’t keep his frequency up when it was loaded. He brought it in for a new engine but when we tested the compression it was high and the motor ran like new. The problem is a lack of power, to say he is upset is an understatement. There are times when quoting the incorrect hp can really cause problems down the road. No shock his dealer wont return his calls…. Another snake.

I do have the manuals for that tractor but they are parts only. I have dealer spec sheets from Japan that are issued to the dealers form the manufacturer and that is what I go off of. If I cant get a spec sheet I dyno it and write it in my book. Manufactures specs are almost always tailored to be high and incomparable with other brands (everything measured at a different point) and that is not an accident. I remember sitting in a meeting where a company was deciding what would be excluded in that model year test. No water pump, flywheel, hydraulic pump and tested at sea level, ect, ect. I also saw a test where they installed a turbocharger for the test then just did some simple math to show what it "should" be without the turbo.
