New 2520 coming soon

jakdeere · Jun 28, 2011

Hi all,
I'm new here to the site. I was just wondering if anyone knows if john deere has fixed the 3 pt arm problems they were having. I ordered mine while they were having the $2500 rebate and it is not due in until the end of July. I did not start reading about the arm rub till after i already signed the paper.

I've had mine for a month and havent had any issues. I saw some of the same threads and if I recall they were posted a few years ago. Congradulations on the new tractor, post some picts when it arrives!:thumbsup:

Welcome and congratulations on the tractor. I bought my 2520 just over a year ago, and I have been very happy with it.

One of the things I found a bit confusing about reading postings here, and on other sites, was drawing the distinction between the 2520 that was made between 2006 and 2008 from the one that has been made from 2009 forward. The issue with the 3PH arms was solved, along with a number of other changes, starting in 2009. I read postings complaining about the lack of a cigar lighter power outlet, which mine has. I also read many postings about problems with the wheels of the 62D deck, where mine has the newer style wheels. I even read some messages talking about how the 2520 engine uses an intake heater as opposed to glow plugs, where mine has glow plugs.

When looking through the parts and technical manuals, it's clear that there are numerous differences that are divided by serial number range between the earlier 2520 CUT and the one being currently produced. So, unless you are buying a used tractor that was made between 2006-2008, you will have the newer style 3PH arms that prevent tire contact.

Thank you everyone for the replies. I will post pics as soon as it arrives.

I have one of the early ones, and I don't see glow plugs as a good change for me. I don't need it nor want it - I live in warm climate - that should be an option IMHO.

Either way, they all have some form of cold-start assist. They just changed the design along the way from an intake heater to glow plugs, either because Yanmar thought the glow plugs worked better, or because their use reduces emissions as compared with the intake heater.

As mentioned in the other posts, no problems with 3 pt arms. Mine are new style and work fine.

I had a 2008 JD2520 that I just traded on a 2011 JD2520. My old one had the problems mentioned, rubbing arms, bad wheel design on 62D deck, both fixed by JD for free. My new one has these things plus other things fixed. My old one did however have a cigar/power plug-in. I'd like to know if anyone can tell me how to tell if my 2011 has an intake heater or glow plugs. I had the dealer tech look at my new one to see what it had and he couldn't see evidence of either one installed on the machine even though it has the dash light that seems to indicate glow plugs. He showed me where the wires for the glow plugs would be and the wires for the intake preheat. No wires or evidence of any preheat device. And of course we all know by now that the manual says nothing about it. If anyone knows how to tell please help me out. Thanks.

Your tractor should have glow plugs. They will be located right next to each fuel injector. There is a strap connecting them all together with a wire attached to the strap at the rear of the engine. In the attached picture, "D" points to the nuts that connect the electrical strap to the glow plugs.

The 2011 2520 is direct injected, doesn't have injectors or glow plugs. It's all done electronically and has eliminated the need for glow plugs due to the design. If you google direct injected diesel engine you can find many websites that explain it better than me.

Congrats on your new machine! I'm waiting on one in mid July.

gary_dsc · Jun 30, 2011

Ok, I'm confused. I googled direct injected diesel engines and saw an article that stated that direct injected diesel engines use glow plugs in each cylinder. My 2520 has the light and starts immediately if I wait until it goes out. If I try to start it before that, the starter has to turn over several times before the engine fires up. This doesn't seem like rocket science and getting a clear answer should be easy. Guess I'll ask my dealer.

Direct injection means that the fuel injector injects fuel directly into the combustion chamber, as opposed to indirect injection where a small pre-combustion chamber is used. As far as I know, the latest 2520's still use the same Yanmar 3TNV82A-BMJK engine that they have used since 2009. This variant of the 3TNV82A uses glow plugs for cold start assist.

Thank you, pdp11, for your concise and direct answer. Now i know the proper starting procedure. By the way, does your handle have anything to do with the DEC minicomputer that was built back in the 70's?

Welcome you will love the tractor. All the issues you have addressed have been fixed by design changes. If you are getting a 200cx loader or are getting a mid-mount mower (MMM) with mechanical lift (not indepedent lift) then make sure the dealer puts the rear wheels in the wide position. The loader manual says that it is recommended for stability and JD had issues with rubbing on the mower lift linkage and that was told to dealers (DTEC) to put the tires in the wide position with mechanical lift. You will find most dealers do not do this for some reason. Still your preference but I would have them wrestle with the tires verses you and the only downfall would be the valve stems will be on the inside of the tire verses the outside and this is how you can tell whether the tires are wide or narrow.

Post some pics of you putting it to work when you can.

Just to caveat on pdp11's post, the direct or indirect injection is just placement of the injector in relation to the cylinder. Injectors of either style can be mechanical or electrical and the injection pump can be either mechanical or electrical.

Your 2520 uses mechanical injectors and mechanical injection pump. The only electrical is the fuel shutoff.

2520 BMJK engines (09-current) get glow plugs and the MJKE engines (06-08) used an intake grid heater (think of it as a toater grid on steroids) for a cold starting aid.

Yes, it does. I know it doesn't quite go with the theme of a tractor forum, but it's surprising how many people make the connection.

Is that your system? I've spent a lot of time programming pdp 8's, pdp 11's and vax's. Programming was real fun with those systems, especially the small 11's. You wrote your own O/S, drivers, etc. I miss that time a lot. Oh well, guess that doesn't have much to do with tractors.

Yes, it's one one of them. That's the 11/70. I also have an 11/83, a MicroVAX 3100, and a Pro350. However, I use a simulator most of the time to save electricity
