Original brochures

You have to be careful comparing lift capabilities - or any specifications - from compact tractor market of the 1970s and 1980s. This was a period where a lot of Japanese tractor manufacturers were vying for the the US compact tractor market. Most of them were publishing advertisements playing fast and loose with specifications. Specs printed in advertisements of the time were often different than the ones printed in their own technical manuals. The advertised numbers were "true" but were also deliberately deceptive since they required a special non-standard interpretation of how these things are measured. HP, loader, and three point lifting specs were favorites. Some Japanese machines were tested at Nebraska and this resulted in an industry outcry. To Yanmar's credit, they were one of the first to publish amended figures. The YM186/187D just might be my favorite ever tractor and the correction to the YM186D specs is in their service bulletin T-020 sent to dealers and dated July 2, 1981. In the service bulletin the advertised lifting capacity for that model was reduced by 38% in order to "select the correct liftable implement". Corrections to other models followed, but I don't know if they ever got around to the later models such as the YM169D. The YM186D correction wasn't all that public or easy to find. And interestingly, Yanmar couldn't resist taking a swipe at the competition in a note appended to the service bulletin.

I am not sure they did on the 169D, the 3 point hitch can lift the front end right off the ground without weights out front.

Yep. This turns out to be exactly one of the ways to pump up a rating that I was speaking of. Obviously it doesn't do any good to lift the front. And so traditionally manufacturers had set their pressure cutout to prevent that from happening. The other way that the specs at that time were misleading was that the lift point was calculated at a different location than where the mass of the implement was located.
None of it stops the YM169D from being one of the best little tractors ever. Tremendously sophisticated for its size.
enjoy, rScotty.

Here are a couple examples of it's lift power. I had to add 200 pounds of weight to the front in order to lift the log with my pallet forks. The photo with the box blade demonstrates lift without front ballast. :confused2:

I have a box blade too; but with a FEL for counter balance; notice; the more weight you (one) puts the further out the more unstable or more counter weight needed. The 3 pt hitch attached to your box blade is out further than most; so more counter balance will be needed ...

Anyone having problems reaching the brochures page the 284 included in the first post?

Looks like that album no longer exists.

Hmm, sorry about that. I'm not sure what the issue is. All of the organization seems to be fouled up at Photobucket.

I will post the entire hyperlink to the parent folder. The lower right corner has options in the "Sub-folders" window to "view all folders." That will take you to a list of each brochure grouped by model.

Domush has a great explanation about how to use Picasa, and shows how one can change the display size of the picture in the link itself. Find it here. I will eventually transfer all my stuff to them, I think. Photobucket was nice to use and easy, but I have noticed a couple other links of mine have disappeared, too. I'm not sure what happened, but I'll experiment with Picasa, I think, on this next project.

Are you looking for anything in particular? I've got a lot of old brochures.

Thanks 284!


Rscotty - there was a thread recently where a new user was looking for tires sizes and I offered to email him the brochure I had but its 9 megs. It would be great to have yours scanned and out on the web for posterity....I doubt you have one for a YM 2020 though!

I help where I can. My literature is largely old sales brochures for the US model Yanmars. And also factory service info plus some specialized implement literature for "Yanmar branded" implements sold here back in the 80s All US stuff; nothing grey market. I've a suspicion that the US Yanmars were mostly the same as the international ones, but with different model numbers. And then there are some -like the YM336D - that were sold worldwide under that model designation. The last new US models were introduced here in the mid 1980s. I think the later models here correspond to the xx10 grey market models but not sure about the xx20 models. I'm not clear myself what the difference is in the YM2010 and the YM2020.
