2520 Questions

[Rogator]

I recently purchased a JD2520 and have some questions.

First how do you use the engine pre-heater? The service manager at the dealership looked it up and said it has one but could not tell me how to use it.
At just above freezing this tractor does not start as good as my 2305 did using the pre-heater.

Second can anyone tell me how much width i will gain by putting my rear tires in the wide position.

Third can the front wheels be put in the wide position.

Forth does anyone think John Deere will take responsability for the three point problem. I find it hard to believe that they have not come up with fix for this. Usually when a mistake is made in the design of a machine the manufacturer resolves it. I'm sure John Deere knew of this shortly after they started building the 2520 and should have at the very least changed the design. When I brought my 2520 home I knew I would have a problem with my quick hitch so i put my snow blower on with out it. I tightened the turn buckles as tight as they could go and could not lift the three point all the way up without hitting the tires. I feel we should not have to change the way we mount our quick hitches or go to the expence of buying wheel spacers. Yes I know this is not a problem with the 2320 but I could not justify that much less of a tractor for only a slightly larger price.

Thankyou in advance for any comments or answers in advance.

Hey Rogator, congrats on the 2520!! I know nothing about a preheater, will have to ask my dealer. When I bought my 2520 and put my quick hitch on it too rubbed the rear tires. I just flipped the rears side to side and tightened the turn buckles and problem solved. Make sure your valve stems are in. You only gain about a inch or so I think. As far as the fronts, why would you need the extra width? As far as loader work, I think in is better, the further out the more stress on the axles, JMO.

It will be interesting to look at the 3pt on the new 2720 when it arrives.

 

[Rogator]

From what I have read the 2720 will be the same tractor with a bigger engine.

 

[ChuckinNH]

Yes, but it would be a good chance for Deere to correct the hitch.

Hi Welcome - Great tractor

Preheaeter - pull out the PTO and turn key to right hold for 15 seconds to preheat - pop in PTO switch and start tractor

Fronts can be set wider - I did mine with the rears - doesn't add a lot but every bit helps in the hills / slopes

Cheers,
Brad

Can i get a link to some more info on the 2720, maybe a pic?

 

[Rogator]

There was a post on the 2720 a couple of days ago with a link to john deeres manual on the 2720. Pretty much the same as the 2520 except for more hp and weight.

Not trying to argue - learning as I go here also...

I was under a fairly firm impression that the 2520 has no glow plugs or pre-heater at all - I'll have to take a better look tomorrow.

As for the front wheels, when I switched my rear wheels to the wide position, I did the fronts also - made no difference in the tracking width of the front tires with the wheels turned either way.

I just got my 2520 three weeks ago.
It was 35 degrees F here Sunday morning and It started right up. I don't have a pre-heater that I know of. I just put the key over to start, a glow plug light comes on on the dash, I listen to it click for about 10 seconds , then key goes one more notch to the right cranking over. It actually 'starts' quicker than my truck.

I probably won't be taking the BH off for a while, although I've got almost all the stumps out that I need to right now. I've got tons (literally) of rocks to move. Some don't even fit in the FEL bucket.


First tractor so it still amazes me how in one hour I get done what would take all day without it. Or wouldn't bother doing at all.


Edit: The glow plug 'light' or icon is on the right side. Looks like a heating element, sort of. I didn't notice it until two days ago. On for about 15 seconds tops. I also never took it out of 4WD by lifting up the little orange lever near the heel of my left foot until last Sunday , either.

I hope this fuel gauge is not a linear indicator because if it is I'm ripping through some fuel.

That is interesting - I have never seen any glow plug light on my dash.
Of course it is ~45 deg F today when I started my tractor, so I wouldn't have seen the icon if it was there anyway!

 

[newt92]

I believe what your seeing is the "low oil pressure" light. There are no glow plugs.

 

[DreaminGreen]

Could it be an air preheater light? Try pushing in your key and see if the light goes on(with out the engine running)...not sure but that is how it works on the 3000 series.



Edit: Oh well ignore this post, just checked the manual online and it is'nt an air preheater sorry.

Interesting on the preheater. I had noticed when I purchased my unit that a heater was listed in the on-line parts listing under the air intake system, but no mention of what you describe in your post was in my manual.

 

[Birdmayon]

I just ran out and stuck my key in my 08 2520, there IS a glowplug indicator that comes on. If you leave the key in the "on" position before starting the engine, the light goes out after about 10 seconds. I know that there are no glowplugs in the 2520, but the light is there. Not sure if it is meaningless or if there is in fact an air intake heater. BTW, it is in the 50's here right now, I don't think this light is temp. dependant. I've seen it everytime I turn my key to "On".

 

[bkennedy]

I have only had my 2520 for a few weeks, but I must have missed where that light is - I don't see it on mine.

 

[Rogator]

I just went and tried mine. When I turn the key on the lights that come on are, on the right side the pto light and on the left side starting from the top
four wheel drive light
oil pressure light
battery light

None of these lights go out until i start the tractor.

My 2520 tractor has a pre-heater that is an engine block heater that heats the anti-freeze like a block heater would.

The glow plugs are activated when the key is on and the high-low lever is in high or low. You can hear the click. There is no light. Just give it 5-10 seconds, then put it in neutral and start it.

Deere will have new redesigned 3 point arms in July according to my dealer. Turning the tires with the valves in will give another inch or two per side till then.

I am replacing my 62 hour 2520 with a new 2520 if anyone needs one.

Not sure why some of you are saying you don't have glow plugs. You most certainly do on the 2320 and 2530. They are standard. When you turn the key to the on positon the glow plug indicator should come on for 3 seconds and then go out. That is when you are supposed to start the engine. The owners manual explains it all.... If your light is not coming on, then you have a problem.

I don't see anything about glow plugs in either the tech manual or the owner's manual for the 2520. However, page 149 of the tech manual outlines the operation of the engine preheater. It says this:

"The preheater is energized (heated) when the key switch is placed in the ON and START positions...

After 15 seconds, the timer turns off and removes the ground path from the 121 Blu/Grn wires and the preheat relay coil. This causes the preheat relay to open and stop supplying currrent to the 33 and 32 Blk/Red wire and the manifold heater...

When the key switch is in the START position, current is provided from the C2terminal of the key switch to the 31 and 32 Blk/Red wire and to the manifold heater...

When the engine starts, and the key switch is returned to the ON position, power to the C2 terminal and 31 and 32 Blk/Red wires in removed."

So, no glow plugs on the 2520, but yes it has a manifold air intake heater. The heater comes on whenever the ON or START positions are selected on the starter switch, and in either case, it shuts off automatially after 15 seconds.
