Looking at buying a disc, I no till and strip till and the last disc I owned was a 1020 Kewanee a long time ago. I've had a few times where the combine would leave ruts and I'd borrow a disk or use my ripper. I've been looking at International 490 and 496 discs (what I've been borrowing) and I've found an AC 2500 that looks good for the same money. It's a 25' wing fold on 9" spacings. When it gets used it will only be to level ruts in corn stalks. Anyone have or had one?

I have a center fold 2500 and it works good. The wing double fold is better as far as frame and pivot points.

About 1981 era, AC built the 2500 as a center fold or double fold with either 7.5” (20” blades) or 9” (22” blades) spacing. As a double fold, the 9” was offered with either non-cushioned or cushioned (rock flex) gangs. The 7.5” was only offered as a non-cushioned. Plain(P) or cutout(CO) blades were available. The non-cushioned specs:
A 25’ 9”P-P weighs 7270lbs.
A 25’ 9”CO-P weighs 7225lbs.
A 25’ 9”CO-CO weighs 7180lbs
A 24’-7” 7.5”P-P weighs 7255lbs.
A 24’-7” 7.5” CO-P weighs 7205lbs.
The cushioned specs:
A 25’ 9” P-P weighs 7705lbs.
A 25’ 9” CO-P weighs 7660lbs.
Drawbar hp requirements:
140hp 20-28’ (7060)
154hp 24-31’ (7080).
I have a 21’ 7.5”spacing, 2500D, double fold disk. Best leveling disk I’ve ever owned. AC built them heavy & with numerous good grease points. Mine has the optional furrow eradicators (smaller disk blades at outer end of rear gangs).

We had one years ago did a good job. Only issue was the wings had a tendency to gouge. The wings had only one tire and it was mounted on the inner spindle mount. We moved the wheel, spindle to the outer position and fixed the gouging problem but then the rear gang didn't quite take out the track. I believe it was only a 25' disc. For your application, that wouldn't be a problem.

Bought 1 new years ago, I think it is a terrible piece of equipment, Very difficult to level the ground with, Get it working in 1 field and move to another and start all over again, Very difficult to work with in various soil types. I personally would never buy one again.

I have a 2300 series AC with the 4 smaller hydraulic wings. I believe they work really great in any condition. And are also heavy.

Considering its only being used to level fall ruts, then either a 2500 or a 2600 model will do fine.
I have a 2600 and think its great!
Yes, with bigger and heavier disks you do have to be more aware of speed (levelling) and gouging if turning too sharp. But that's normal regardless of make.

2500 is an excellent disc. The gang angles are adjustable to control how much penetration there is. The one-and-only complaint I ever had on ridging was a guy who wanted to disc at 7 MPH. I rode one round with him and tipped my hat and told him to slow down to 5 to 5.5 MPH and the problem was solved. He bought a disc too small for his tractor is what it amounted to.

The Allis 2500 series disks, were one of the best kept secrets in ag, great disks. The first year we had one, I was going to use it to put in oats. Dad said that it was way to heavy, and we needed to use the 13' Kewanee. Well it started to rain, and needed to get the oats covered, so we went with both disks. It was real easy to tell which disk went where, as the 2500 stand was better and, came up more even.

I also agree with the 2500 center fold disk. best disk I've ever owned! I do have a 470 IH and a 496 IH, some of my fields were uneven, the 2500 disk flexed good in those areas, the others would gouge.

oh...and if you do go with either of the IH disks, go with the 490, it'll work better than the 496.
