Nuru, I was scared of my JD 3520 just running around on level ground with the was it was set up from the factory. I don't consider myself scared easily either. I also had 11 years expericence and 2100 hours on a JD 870.

The unverferth wheel extensions where a must for me. Of course the 3520 will do only about half the 32.6.

Gee, my slope is not that bad, but again, it is steep!

Hos do you accurately measure a slop like this? This is as close a pic to my pond sides as I have seen.

Hi:

There may be an easier way to do this, but this will work. Take a board of a known length (let's say a 2x4x8). Place it on the slope and hold it level. Measure the distance between the downslope side and the ground vertically (plumb). Divide this distance by the length of the board. Then on a scientific calculator (or a computer) take the inverse tangent (TAN) of this number.

I.E. Let's say it was 8 feet across the board and 8 feet down to the ground. 8/8 = 1. the Inverse Tangent of 1 is 45 = 45 degree angle. If it was 8 feet across and 4 feet down 4/8 = .5, inv Tan of .5 = 26.5... degrees.

Oh, and make sure the calculator is in DEGREES, and not in Rads or Gradients or this won't work...

The 870 was more stable? That's rather surprising since the 3xxx series aren't that much bigger then the 870 tractor.

Roy, I could take the JD 870 places I would not even attempt with the 3520. Now even with the 4 inch extensions there are a couple of places that I still won't go with the 3520.

Dirt,

Is that because your 3520 is a cab model, or would you feel the same way regardless, even if it was an open station model?

Roy, those cab models look very cool, but stock, they are very easy to rock from side to side due to the high CG. I thought my local dealer was gonna send one over on its side showing me how easy it was to rock them without the wheel spacers.

dirtworksequip · Apr 30, 2007

superduper,I'm sure the cab model is somewhat easier to roll just because of the higher center of gravity. I've never run an open station 3520 so I really can't say how it would feel compared to the cab 3520 or my old 870. It would be interesting to see just how much difference the cab makes.

Sincerely,
Dirt

Good technical pics dirt. I am gonna try my unit out with the turf tires this weekend and see if the spacers are still required.

Hey Nuru did you end up getting the spacers? I am picking up my machine soon at the dealer and I asked for good turf tires. Is it the R4 tires that make this machine more tippy then the turf tires would be?

Not yet DP, and its is the R4's that make the machine more tippy. The Turf Specials (wider than normal R3 Turfs) I run, really made a difference in a positive way. Having a cab, anything one can do to make it have a wider stance is good.

I'm looking to purchase the JD 4" wheel spacer kit for my 3720 cab tractor. However, my JD dealer says he cannot find any info for ordering. Does anyone have the info for ordering? Thanks in advance.
Regards, John

Deere dealers around here look like a deer in the headlights when I mentioned extensions and weren't any help at all.
Through ideas from this forum I got 2" spacers for my 3720. I put 2 spacers on each side for a total of 4 per side. I think it cost about $350 from Skid Steer. They work great and I think that is cheaper than Ovenworth.

I keep toying with the idea of getting a set of 2" spacers for each side with my Turf Specials, so I can get a stance of 68"+

The red skid steer 8 lug 9/16" extensions on eBay for $329 space out each wheel 4" for a total of 8" increased track! They fit the cab and open tractors.

I had those red spacers on my 3520 and really liked them. The made the tractor feel bigger than it was, and was more stable on slopes. Was the right thing to do. I wish I would have taken them off when I traded it, and sold them.

I run an open station 3520 myself, but I don't think the cab would make much difference. The weight of the cab is negligible compared to the tractor's and shouldn't raise the center of gravity noticeably. Besides, when you get used to it (took me some time), you find out the 3x20 is quite stable, it's just that we are not used to high narrow machines, the top-heavy impression is much more appearance than reality. I haven't read people roll them more often than other machines.

I just got some 6 inch spacers from Uverferth there black. I think once I install them I will flip the tire back to the stock way as I don't need 8.150 inches per side. I don't know why the dealer got me 6 inch spacers but that is what the company sent for the 3720. I am still a little worried about the installation there is a sticker on the spacers that says they are for a John Deere 4000 / 4010 series- local dealer says tht uverferth says there the rite ones - do any of you know if the wheel hub is the same on the 4000 series as the 3000 series?

There the wrong ones there 6 bolt ...wtf? my tires are 8 bolt why are dealers so dumb sometimes..****! This is why a good company should let the public deal direct with them, now I am going to ask for my 600.00 dollars back and just order the ones from ebay..!@W!@#

The 3720 spacers are yellow is this correct and only 4 " ?

sunnyside360 · Sep 18, 2011

I got my wheel spacers on ebay at Skid Steer Solutions. They are red and come in four in a set. I put a pair on the 3720 rears and a pair on the 4320 rears so they are identical. Widened each tractor 4" total and makes a huge difference in pucker factor. Unverferth spacers were 2 or 3 times more expensive so it was an easy decision for me. You could double up on the spacers from Skid Steer Solutions on each side and increase the overall width by 8". I spray painted mine with JD yellow paint prior to installation and you wouldn't even know they are on the hubs.

I too have been looking for spacers for my 3320 w/cab with R4's...first tractor I have ever had that feels so tippy....didn't want to go with the 6" Uverfurth (little bit too much)....I assume the correct set for my 3320 from skid steer would be the Skid Steer Wheel Spacer 2" x 9/16" Stud 4 pack...for $350....that figures...just went to check and now "currently out of stock".

And now an update..called skidsteer spoke with a very pleasant Aussie...apparently they are not out of stock.

Here is where I got mine about a year and a half ago.......

I paid $300 plus free shipping ...... see they went up in price since then.
