I opted for the smaller R4's for lower center of gravity and it just fits in my garage for height (with cab). Most of the 3x20 tractors sitting at JD dealers around here have the smaller R4 tires -- suspect it's because of the predominantly hilly terrain. Come to think of it, I've never seen one with the larger tires. Interesting thought though, the larger tires filled with ballast could be better center of gravity than the smaller tires filled with ballast.

I have wondered about the performance difference between the two but have never seen any comparisons. Looking at the larger size design it might be less damaging in turns on wet turf, but that is just a guess. Anybody have experience between the two in mud, snow, grass, etc.?
Sunnyside,
I was wondering myself about the larger tires and center of gravity. I did notice they are also wider in the back which may compensate. I wonder if this will create problems with the 59" snow plow though.
I can always change back to the standard tires but my thinking has been to go with larger tires, especially for muddy or snowy conditions. If you look at the R1's you'll see they are the tallest of the bunch, also the thinest.
Anyone got the larger tires or the R1's? iwas wondering what the overall height of the larger tires is as compared to the standard tires.
My garage has an 8 foot door and I never thought about the total hieght of the tractor difference. Actually this could play a factor in my change to standards. Deere show the height as 83+ inches, could the larger tires really bring it up to 90"?

R1 is the tallest and would fit 8 foot door, taking door frame overlap into account. Close though. My 8 foot door can clear 93.5 inches.
Height From Ground (Tractor without cab, with standard R1 tires)
To Top of Folding ROPS 2.4 m (93.3 in.)
Height From Ground (Tractor with Cab, R3 tires)
To Top of Cab 2.3 m (89.4 in.)
You better find one to measure. Deere is not always very good about accuracy of their specs. I see your 83.7 inch number in their brochure. It also shows the 3120 as just 80.8 inches. Above is from the owner manual.

They have been available since the tractors were introduced.

The overall width of my 3720 with small R4's is exactly 55". That is measuring from the outside of the tread on the left tire to the outside tread of the right tire, ie, the width that contacts the ground -- no problems running the 59" front mounted snow blower or snow plow. This is all fresh in my mind as I am looking at installing wheel spacers to improve stability on hills when mowing. It would be best to find and measure a 3x20 with larger tires that you are considering.
Regarding traction, I've had no issues in snow yet after three winters but I have MFWD engaged at all times in the winter and occasionally use the rear wheel locking feature when needed. Tires filled with RimGuard also helps.

Isn't that the truth. As an example, Deere recently changed the R4 rims on the 4x20 series from variable width to fixed (welded) and the spec's and Owner's Manual have not yet been updated. I got surprised with this on my recently purchased 4320.

I've got a cab machine...couldnt tell you about the ROPS height.
Stability...could be worse, could be better. My land is as hilly as a football field so its not a big thing for me. But when playing in the dirt I've gotten scared before... Once my bro was using it and got scared but from the outside it didnt look bad at all. I think because your seated so high to begin with it makes it feel worse then it actually is...which is a good thing I guess.
Overall I think the stability is fine, just like the cab, you learn quickly what to avoid, where you can & cant go, etc...
It's not that much higher than the standard tires, is it?
I sat in a cab at the dealer and didn't care for it. I don't remember if it had the big tires, when I go back I'll check.
If I had 40 acres to till and seed the cab would be my choice but the longest stint I have is hogging an 8 acre field which goes pretty fast. I do it on nice days and like being outside in the elements. However, snow blowing in the winter up here does make the cab sound enticing!

Dunno... using 20/20 vision (driving by my dealer at 20 mph & 20 feet away :laughing
the larger ones look quite bigger... dunno if its the design of the tire that makes it look so much bigger, or they actually are alot bigger.Whether its -40 below out or 98 out, I love my cab, heck even with its 65 out I love it because it keeps the bugs out...I only have 2.2 acres but I wouldnt ever go without a cab. I remember thinking like you when I started my tractor shopping experience...my dad told me "if you dont buy a tractor with a cab, dont buy one at all", the biggest reason I didnt want the cab was $$$$$$, that chunk of change woulda paid for 1/2 my garage which I still havent built
.....they say wisdom comes with age...and my Dad was right :thumbsup: it may have delayed my garage build by a year or so, but it was worth it.

I have to agree with Dave. Just for grins, I counted up all the tractors (excluding lawn mowers) I've had during the past 45 years, and I've owned 11 and all were open station until the last two which I have now. With the cab you stay warm and dry in the winter, cool and dry in the summer, free of insect bites and stinging bees, and if you have allergies (like me) it's an absolute must. IMHO, Deere makes the best cab tractors. You can also listen to the radio if you want. Not sure there is a down side to a cab tractor other than the additional expense when buying but if you spread that over many years of ownership it's not that bad.Whether its -40 below out or 98 out, I love my cab, heck even with its 65 out I love it because it keeps the bugs out...I only have 2.2 acres but I wouldnt ever go without a cab.

Thanks for the advice Dave,
I've been running tractors for several years now so the 3320 won't be a virgin experience for me. I can afford the cab, that's not it, but I'm in and out of the seat constantly with the fruit orchard.
Because I'm basically retired now I can wait for the weather to clear before I plow in the winter which is what I usually do.
I spend a lot of time in front of the computer designing electronic circuits for my magazine articles so when I get out I want to be out, so to speak!

ps: I know about the mosquitos up in Maine. I remember having them carry my tent away when I was a kid camping up there!
