3520 and MMM and Super Turfs?

Nuru · May 31, 2008

Also aren't your tires 41" tall, 14" wide for the rears and 27" tall, 8.5 wide? Then it really looks like it probably will work unless the offset of my wheels is so different it makes the tires not work. I am keeping my fingers crossed.

Most of the measurements were from the middle of the tire, except for 2 that were from an outside edge to a gauge wheel.

Fronts are 27 - 8.50 x 15
Rear 41 - 14.0 x 20

The pics were all taken with the wheels in the narrow position, however, today it was raining and with nothing better to do, all the tires were moved to the wide postion.

Unless, as you say, the wheel offset is way different from the R3's I wouldn't think another 2" width would be a problem.

If you would like, I can take another set of pics in the wide postion - but not until Monday. Let me know.

Yep, i thought the tires sizes were correct, thanks for supplying those. Oh, if you can, yes those pics would be great from the wide position. That is interesting as one of the JD mechanics was not sure but thought there might be a possibility that the MMM would work only with the tires at the narrow position, seems you havve put that to rest.

The pics from the Wide setting would provide an even more conservative view of the clearances. Right now it looked like there was a lot of clearance. Those pics of the 4310 I uploaded were with the tires all set on the widest setting, and the clearances were fine.

Here are the new pics.

MMM is in full up position.
R3's are in Wide postion.
Broom handle is touching outer edge of tire.
Right Rear looks like the spot with greatest potential for conflict.

Bad News. After all the pics and measuring, I had time to take the tractor out of the shed. With the front R-3's in the wide postition there is interference on hard turns, both in the full up and cut postition. The Gauge wheels are not the problem. On a hard turn - either direction the tread of the tire that turns in towards the center of the tractor hits the mower body.

If you look at the pics you took of the mower the interference point is to the inside of the "Danger" label, an inch or two towards the middle of the deck from the weld on the mower lip. On the left side, for example the contact point is approx. 14" in from the center of the tire, measured with tire straight forward.

Hills and perceived stability are not a big factor for me, so I think I'll switch the fronts back to narrow position.

Hmmm, so you can go wide with the rears without issue, and that is the most important thing to me. The wide rears will work for me as far as stability. I have yet to try the loaded R-4s too. I got the smalls so I am not as high up as the big R-4s. I figure the deck will add a good amount of weight to the lower portion of the tractor and reduce the effect of the Cab.

thanks, once i get the unit back I will try it out and see what happens, and i will report back.

Nuru do you have a lot of hills you do, I assume you do since it sounds like you're having some tipping issues with the cab 3520? I'm just curious since I'm getting one of those-

Yes I have some slopes to mow, however, I have two areas where the ride can get a bit scary, so I am gonna try to make sure that incase i forget or get distracted while mowing I have some capabiltiy of mowing there without extreme worry. It does not look that bad when I am standing there but on the tractor it does feel a lot more scarier. If I can get the Turf specials on (narro in the front, wide in the rear), with that tire change and the MMM, the stability should increase a bit, hopefully dramatically. Regardless I am gonna be careful when mowing that area. As I get more used to the tractor, I will be more able to judge what is going on as far as stability.

I have small R-4s and since I just got the unit and any bump that causes a rocky ride can be startling. I am probably more anxious

about tip over than I will be in a few months

. so I have to learn the characteristics of this unit versus what I came to expect on the 4310. I will almost be as sure about the 3520 cab as the 4310 at some point. I jusat need to learn how to best use its capabilities. Let me tell you the loader action is sure sweet on this unit.

And i am toying with the I dea of hooking up my portable SAT Radio up in this unit.

I don't have much experience using weights or ballast but I assume that might help as well if you weighted the tires- What do the MMM go for used? I would think it would be easier just to add a RFM, or is the main advantage of the MMM the stability for you?
Fortunately I have mostly flat land but there are a couple slopes where turning around may be interesting- like you said getting the feel for it may take a little time.
I will be doing the same thing and adding my own radio as well
