2515H or go bigger?

I have the older 3 range trans on my 3725 and I can't use high range at all. Even with the small IND10 wheels/tires that lower gearing. It's only good for roading on level terrain, and there's only about 100' of that on my property.

My property sounds similar...not much flat ground as we sit atop the end of a little finger ridge, with sloped ground in all directions (down in 3 directions and up from the house to the road in front).

You have not specified your location so we do not know how warm it is near you. Nor do we know if altitude should be a consideration.

Nor can I write about Branson tractors from experience.

With other brands, factory cooling capacity increases with tractor horsepower.

HST tractors run hotter than gear tractors.

High altitudes tax engine output. You have to open the throttle further to compensate, so you will run wide open more of the time.


I currently have a ~3000 lb (including loader) John Deere 33hp machine - it is fine for most things, but its lightweight and low loader capacity limit certain tasks.

Assuming your Deere FEL weights around 800 pounds, your Deere is around 2,200 pounds bare tractor weight. (It would be less confusing if you simply specified Deere tractor model.) While an FEL does add weight and dirt in the bucket adds more, weight in front of the tractor leverages weight off the rear tires, negating some ( all? ) of the FEL weight bearing on rear tires, so tractor pulling ability barely increases.

If you upgrade to a 3,000 pound bare weight tractor you will notice some capability increase and considerable stability increase. If you upgrade to a 4,000 pound bare weight tractor you will be equipped for your lifetime. I recommend the Branson - 20 series - 3520h.

Most reasonably operated tractors under 3,000 pounds bare weight operate in residential or hobby farm applications on one to ten flat acres.

When considering a tractor purchase bare tractor weight first, tractor horsepower second, rear axle width third, rear wheel/tire ballast fourth.

BUY ENOUGH TRACTOR THE SECOND TIME.​

Good points about FLAT ground. Most of my 13 acres are sloped.

Tractors are inherently unstable operating on sloped ground. Tractor rear wheel/tire spread, sometimes adjustable, is a critical factor increasing compact tractor stability working sloped or uneven ground. A 6" to 10" increase in rear axle width substantially decreases tractor rollover potential. Tractor width is an approximation of rear axle width.

According to tractordata.com your Deere 955 rear tire spread should be adjustable from ~~50" to 59"~~.

I have a F36Rn. This is equivalent to the 3515R in the US, although with some significant differences. The most important being the "n", which means narrow.

My tractor is setup as a Narrow tractor, which means a narrower front axle and a narrower stance on the rear by playing with the center plate on the rims, which puts right at 1.4 meters wide or 55". These Korean tractors also are setup a lot higher than the European tractors we're used to. That sure took some time to get used to it.

Anyways, I've worked a lot on some serious hills and will work more in the future and even though my tractor is setup as Narrow, it's still pretty damn stable. I've always felt very safe when working with my tractor on hills and the tractor didn't gave me that tippy feeling at all.

It weights 1400 kgs from factory, plus six 17kgs front weights and the dealer filled my rear tires. I also have a homemade hydraulic winch on the front that weights somewhere around 80kgs. This puts the overall weight of my tractor (not including loader or loader brackets) of around 4000 lbs. With loader is probably somewhere around 4800 lbs.

The wider option I had next was the 5025R, but just too big for my needs and too wide of a tractor, although I'm sure it would've been even more stable.

With all this being said, I second the others that said to go for the 20 series and something around the 35+ HP. The extra weight and width will make you feel much better and much more stable working on the hills. Also, I find the 25HP on the 2515 to be a bit short for such an heavy tractor, pretty much makes the High range useless on any kind of hills with the hydrostatic transmission.

Yes...first thing I did when I got the 955 was flip the tires for the wider stance and then fill the rear tires as well ~105lbs each.

Branson 20 series (and probably the 15 series as well) come with one of three wheel/tire packages: IND10, IND20, and IND25, in order of size. The IND25s come on the 4720 or 5520. The 20 and 25s have adjustable rear wheels, the 10s are fixed.

My 3725 normally comes with IND20s but on hearing about my property the dealer suggested using IND10s and 2" spacers. It puts the tractor an inch or two lower which is good for stability. There's less ground clearance of course but that has not been an issue for me. The dealer also had the rears filled with Rimguard. I can't say what the improvement is with the smaller wheels and Rimguard as I didn't operate it without them but I'm sure they help.

The back half of my land is really steep and wooded, so I can't operate on it except on the roads across it. But I mow part of the less steep front half, which is still in the 15-20% range. The tractor's quite stable on them, unlike my old Kubota.
