JD 950 - is there a Yanmar Equivalent?

[Scotty Dive]

I just picked up a 950 and think there is a brake and hydraulic leak issue. Any chance this tractor has the same set up as one of our Yanmars?

 

[careyo63]

The YM2500 should be. It's basicly the same setup and differences as the Ym2000 and the US JD.Ym240 That is what was told to us by a Fredricks Supplied UTDA dealer when we bought it.

 

[clemsonfor]

Getting rid of the 2020, or you just got a deal on this one? Going to fix it and keep it, or sell it, or sell the yanmar? Just curious, its not like im anywhere close to buy either and im not in the market anyway?

Ym2000 and the US JD.Ym240

Uh ...

YM240 was unrelated to JD. It's from the era when Yanmar had their own tractor operation here in the years before the Deere contract.

Deere's Yanmars started with JD 750, 850, 950 etc and I think only the smallest was two cylinder. I thought JD850/YM2500 were the only near identical models.

Scotty I expect your brakes and hydraulics are generic Yanmar parts used across many Yanmar models.

 

[chriswheeler]

The JD 850 is close to the Yanmar 2500, the JD 950 is close to the Yanmar 3000. They all use slightly different engines and gear cases, clutch setup is different as well. Clutch on a JD 950 is a live clutch, where the YM is just a single disc. Engine in a YM 3000 is a 3T84 where the engine in a JD 950 is a 3T90J. Deere has just a little more power to the ground. Interchange between YM 3000 and JD 950 is about 70%. I have had both tractors for quite awhile. Be carefull when trying to interchange parts, Hoye can help you with this one. Buying parts over the years for both I've noticed that the JD parts run almost twice as much most of the time. Also they aren't supporting them as well for parts like they used to do. I try to use Yanmar parts when ever I can on both due to cost. None of the John Deere tractors are 100% exact for any Yanmar model. I'll know a little more about this as I go into the JD gear case next week to work on 3rd gear.

Chris, thanks for the specifics! I had never seen that information before.

I see the site highlighted and linked 'Deere' for you. They did that to my post above too (so I changed it to 'JD'), and they probably will in this one.

I think we've been commoditised, or trolled or something, whatever the marketers call it when potential customers are herded to them whether they wanted to or not.

 

[clemsonfor]

So yall did not put those Links in the text? I though you did that and somehow changed the www.blabhblah.whatever to the link where is just said "John deere".

I still dont know how to do that like you always do. I mean California when you say " see my orchard HERE" and "here" is the link to your tread with pics of it.

I believe this is what I was remembered seeing. Near the end of the JD US240 era.

To insert a photo in your text: Use the yellow 'picture' icon in the msg reply screen.

Bring up the photo you intend to link, in one window. Highlight and copy (CTRL-C) its URL shown in the browser heading field.

Then go back to the reply you are drafting, put the cursor where you want the picture, click the yellow icon, and insert (CTRL-V) that URL into the box.

Or: To simply highlight text and make it a link: Same as above except highlight your text then click the 'earth-over-chain' icon and insert your URL into that box. The URL you bring in can be that of a photo, or the URL over a thread, or the URL of an unrelated website.

It's easy enough that I can do it: Type this: "". After the equals sign, copy and paste whatever the web address happens to be. Outside the close bracket, type whatever you you want to include as the highlighted text. Then, finish with (open bracket) /URL (close bracket).

I had to put the brackets in parentheses as text, because otherwise it won't show up. Just use brackets of the type listed first. If you push the quote button, the format that appears is the same, except you write URL and use a web address, rather than quote and a posting number.

Carey, I wrote that page back around 2004 after nobody could tell me anything about the YM240 I bought. As I learned stuff, I added it into that explanation.

I intended to say YM240 was sold here independently by Yanmar before Deere (highlighted again?) negotiated the contract to get Yanmar as their supplier.

I like to think that YM240 spooked Deere. As soon as they saw it and tested it they immediately recognized they had been outclassed.
Ok, that's how urban legends get started. Somebody has to make them up in the first place.

Had a good chuckle when I opened it up and seen it.

Good info -

Glad to hear this is mostly Yanmar....I sure looks like a lot like my 2020D....And I AM KEEPING MY YANMAR!!!!!:laughing::laughing::laughing:

I got this one because it was such a deal....could not resist. I will get this old gal fired up and running again and then sell her and the JD 906 bush hog it came with.

Here is my question....which I posted in the JD section too. The tractor was well maintained for the first 25 years of its life, but the last 5 years the 2nd owner didn't use it at all and left it outside. He said the last time he ran it the brakes were shot and with less than 500 hours I don't believe that. He opened the left side brake access area and he said there was oil in there. The brakes are mushy and do not hold and I have not tried to adjust them yet, but the oil concerns me and when I checked the hydraulic fluid it was empty on the dip stick.

So my questions is...do I refill? Is there an oil/axle seal in there that probably dried up and leaked? - Hard job? I haven't crawled under this yet, but so far I have not see where the hydraulic fluid would have leaked out???

These arent wet brakes are they? The low fluid level means maybe that the brakes are not filled enough. and that maybe they just need to be adjusted? Got no idea, im kind of thinking there not meant to be wet though as most yanmars are not wet.

 

[284 International]

This thread says it has dry brakes, so if the brakes have any oil on them it is reasonable that leaning hydraulic fluid could be the culprit. Are both sides bad? I'm assuming these have a mechanical linkage, not hydraulically operated brakes.

I would figure out the leak situation first. Put some fluid in it, a catch pan underneath on a tarp or drop cloth, and see what is leaking where.

Congrats on your purchase!

There is a seal on the shaft going into the brake housing. You can go to John Deeres parts sight and look at all the parts drawings and parts. You may need to register and then search under model number. I have tried attaching their drawings here before and it doesn't work for some reason. I am trying again. Look at the http://jdpc.deere.com/jdpc/servlet/...rvlets.HomePageServlet?search=model&model=950

 

[chriswheeler]

One issue I didn't address to well was the product support I'm seeing with the YM3000 VS the JD 950. We that have been here for awhile have seen threads where parts for these
"Gray Market" tractors are harder to find than products originaly intended for the U.S. market. Hoye does at least as good a job supporting YM grays as JD does for it's Yanmar made products, sometimes I think better. Now I'm sure if you had a new JD 3320, the parts would be right there. A little different for a 1984 JD 950. A few parts for the 950 I've been told are not available. ( at any price ) I've never got that answer from Hoye on any part I've requested for my YM 3000. ( important to note that no other major parts have been needed other than what one would call service parts ) This spring after the clean up and repair session, the 950 goes up for sale. 950 is a great tractor, just wondr how long it will be supported. It could have had a harder life in service, but the YM is a 1977, the JD is a 1984 ??? I don't think anyone outside the factory in Japan has the factory part interchange manual, sure they don't want it in the public domain. Think anyone that could get a copy of this would have a gold mine in information.

Chris, I don't know about Hoye. but, I know that Fredricks (at 1 time ) had some older JD parts. You may want to visit their site or call. My 3110D is also supppse to be the sister/brother to the JD 950.

 

[chriswheeler]

I have them bookmarked as well. If your 3110D has a turbo, it could be closer to a JD 1050. Same engine as a 950, just added a turbo. Just about to split the 950 and change the gear cluster that has 3rd gear. Once I get a parts list will give them a call as well.
To the OP, the breaks in the 950 are listed in eBay as fitting the YM 2500,3000,3110 as well, same part. Just put a set on my 3000, case was dry when opened, you might have a bad seal.

No turbo on mine. Cardoc has the turbo ( jd 1050). I had my ol shoes relined. Don't remember the cost.but, it was less than new shoes.
