I just bought a Yanmar 187D used. I took delivery a couple of days ago. My question is that I looked at the serial number plate and it says the model number is a "YM180". I know that in previous years the 187D was the 186D, and before that it was the 180D, is there a chance that they never formally changed the model number of the serial number plates? Or is there something funny going on?Also the serial number plate indicates the weight at 4,150 pounds. Can that be right? Any help or info would be appreciated.Thanks,Mike

Not sure what you have. How does it run? That's the important thing! The 180D was a collar shift 4+R manual transmission with high/low range lever. The 187D was a power shift with a lever on the dash to select 1,2,3,R in any of 3 ranges. So was the 186D, I think.....not sure of the difference between the 186 and 187. All three tractors used the 3T72 engine which is identified by a tag on the right (starter side) of the engine block. It says engine type, HP at RPM, displacement in liters, and engine serial number. Nothing on the tractor from Yanmar ever listed a weight. The transmission and engine tag are your best identifiers.

Thanks for your reply. The tractor runs great. It does have the Power Shift transmission (1,2,3, & Reverse on dash with 3 ranges), so it must be a 187D, and Yanmar obviously never formally chnaged the model number on the serial number plate. But the serial number plate does make mention of weight and it specifies 4,150, I don't know if that is the tractor weight?, Towing Capability?, GRoss weight with trailer?, etc.
Also does any one know what years the 187D was manufactured?
Thanks,
Mike ....

Mike, I think I have it figured out - at least on the model type. The 187D had ROPS and the power shifter mounted on the dash. The 186D did not come with ROPS as standard equipment and the one picture I have shows the power shifter on the floor. This doesn't jibe completely with my memory, but is the best I can do. I do know that power steering was an option for about $1000 for the 186/7 series and components for it are still available.
As for the tag, that has me puzzled. Where is that tag located on the tractor? Could you send a picture? ....

Roger,
What's ROPS? As far as the rest of it, you're right. The tractor does have an emblem that says 187D. I don't know why the serial number plate indicates the model as a YM 180.
Thanks,
Mike ....

Mike, ROPS=Roll Over Protection System (or Protective Structure), i.e., roll bar. ....

I talked to a Yanmar tech. person about the difference between the ym186 & ym187. The ym187 has an improved transmission & a longer wheelbase, so a belly mower could be lifted higher. The ym186 belly mower couldn't raise very high due to the short wheelbase. At times it would get hung up on uneven ground. ....

OK, with Len's new clue I went back to my ol' Yanmar literature and found some interesting things. Yes, the 187 does have a longer wheelbase, almost 10% longer. And the transmission shifter is moved the traditional position to the dash.
Mike, the 186 used the 3T72HA engine while the 180 and the 187 shared the 3T72HAN engine. (the engine number has meaning. It is a 3 cylinder tractor engine with a 72mm bore. "H,A, and "N" means some minor modification to the basic design.) So it would mean nothing for a 187 to have the engine with a 180 tag.....they are identical.
The YM187D does weigh more than the YM186D...1658 vs 1344 lbs. - which is sort of hard to believe. And the 3 pt hitch is rated at 1036 lbs vs 661.
In case you are wondering, that YM186D was the tractor that I lusted after some 20 years ago....It was just slightly beyond my finances - which is how I ended up with the YM165D - and why I still have some old YM180/186/187 brochures. The YM165D turned out to be a fine machine, and led me to all sorts of interesting times with compacts.

What?! And lose my position as a guru of rare and hardly known US Yanmar information? Not a chance! :-) So I'll make you an even better deal. ... This brochure is an advertising sheet, so the copyright is designed for distribution....Why don't I just scan it for you and send you a copy via email? How about it? Ready for a 4 meg download?? By the way, if you have the accessory power steering, I have info on it as well. ....

Is there any chance I could get the power steering information from you? My brothers 187d is currently experiencing some power steering problems and we can't find any info on this setup!
Thanks ....

The power steering just quits working, but sometimes if you crank the wheel to one side or the other and hold it there, then it will work again for a short time. We found a small leak in the pressure line going to the cylinder and fixed that but it made no difference. It seems like an air problem to me but we were hoping to find a drawing or schematic of the system to gain a better understanding of how it works. Thanks again! ....

Could you please send me the drawings from the manual? My neighbor's power steering went out and I plan to try to repair it for him if it's within my capabilities. The cylinder has had hose clamps on it since he got the tractor several years ago, but the power steering stopped working last fall. ....

I think you have that backwards Winston.
One kilogram is 2.2 pounds, so 4150 kilograms would be 9,130 pounds.
I suspect the weight reference is to a gross weight rating for that chassis.
Best of luck. ....

I make my share of silly mistakes too, you're not cornering the market on it yet.
As for the getting older part, it's a fact of life brother.
As my grandfather said when asked "What's it like to be that old?" at his 100th birthday party;
"Getting old isn't much fun, but sure beats the alternative!"
Best of luck.

Thanks for reaching out to Roger Loving. He was one of the great experts in the early days of Tractorpoint with thousands of informative posts. He really knew so much about tractors!
He is still with us in spirit as his last post was over 12 years ago, though I would love to be surprised with a post by him saying the rumors of his death have been greatly exaggerated :-)
Lets hope someone other than Roger has some info on the Yanmar 187D Tractor
