 Yanmar 187D information

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! Smile 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.
