Hi uall, I'm getting a JD 224T baler and was reading the manual and in the specifications it says that the size tractor is a 3 plow tractor. How does the number of plows relate to the HP? This model also comes with an engine and it is 26.2 HP. With effenciences and all I would expect the tractor pto HP to be more than the onboard engine. Any help would be great. Thanks

In the old days they rated tractors by the number of plows they could pull. How they rated them is a question I can't answer but I am thinking they figured it by pulling the plow thru the easiest soil they could find. It most likely was previously tilled soil as well.
A rough number is 15hp per bottom so a 3 plow tractor would equate to a 45hp tractor.

Don't know about the 224T, but my 214T manual says that the power required is "JD 520 tractor or equivalent". The 520 has 39 hp at the pto.
The pickup width of the 214T is 53" (inside dimension) and 62" on the flare. The compression chamber is 14"x18"x40" long. The plungerhead operates at 65 strokes per minute (under load) and the stroke length is 28". Don't know how these specs compare to those for the 224T.
Hope this helps.
Thanks Robert, after I posted I did a google search and found a couple references to tractor models that were 3 plow tractors. I looked up the tractor in my blue book and it was 39 HP PTO so what you are saying matches up with a 45 HP tractor assuming you loose 6 HP between the engine and PTO but close enough. That tells me that the change in power direction on the baler that happpens when you use a PTO instead of the engine you loose about 12 HP. That's about a plow not very effecient change of direction.
I used to run a 24T baler with my 22hp Yanmar just fine. (dropped bales on ground or pulled a 8x16' snowmobile trailer with a kid on the back).
Keep the plunger knives sharp and the ground speed suitable to the machine and it will be happy.

Just out of curiosity, what's the model number of that Yanmar?
I assume you mean 22 hp on the pto.
How does that 24T baler compare in size to the 214T?

If your baler has it's own engine on it, you just need a tractor heavy enough to control it.
If it is pto powered, the baler itself uses 18 hp or so, pulling the tractor & baler takes about 10 hp, and pulling a rack takes about 10 hp, so 35 plus hp would be good. In today's world, you also need a utility or better class tractor, compact class typically have light drivelines that can't take the feedback from the baler flywheel, and often are too light weight to safely control the baler.
You want live (or independent) pto on the tractor as well.
Many balers of this size were pulled with Ford N or IHC H tractors of 28hp and no live pto, so it _can_ be done with less, but it is not an enjoyable or good setup. It will work.
Using a compact tractor of even less hp can work short term because of the slow slow gears, but can easilly shell out your driveline, as the flywheel on the baler may store 50hp or so & shock back to the tractor. As bales push out the back, the baler will be heavier in the rear than the front with wet bales, and lift a very light tractor. A baler is heavy, and difficult to control with something too light. It is not a good situation and I would think long & hard before trying such.
