45 hp seems a bit low. Most 4440s have no problem putting out 120 PTO hp. My uncle ran a 6601 with a 6400, which has 85 engine hp. It handled it nicely.

Combiness your way off on the HP.

A 4430 was around 125, and the 4440 was around 131. They could put out lot more depends if the farmer tweaked with the fuel pump and injectors. There is a 4430 running around my house putting out almost 150HP.

I agree either one of those would pull it well. I have saw a pic of a 150HP 4630 pulling a 7721 combine before.

Those PTO combines usually don't require a lot of HP to pull.

Find a brochure or someone that has one already. And they can tell you what the HP requirement is.

I found a pic of one being pulled by a 4430 in my book.

If I followed minimum HP requirements on all my stuff, well, at least I'd have bigger tractors!

As with any combine, depends on ground conditions, terrain, crop, crop conditions, size of the head, etc. etc.

And nobody will curse at you just because you have a Case. If it runs good and works for you, enjoy! I'd like to come see you use that 6601, that would be cool!

Regardless your off on both of them.


The numbers you told was more like on the #30 combines. Even the #96 required a good 60+.

Even the SP versions had more than just 50HP to run. Like you stated. The 6600 came with around 104, even the small 3300 had 70 to run it. Only combine that had around 50HP to run was the 45 and 40 combines. By the time the Titans came around not 1 combine had under 100HP. PTO combines requires just about the same. The tractor has to run it and pull it.

However yes around 50HP could run it. Just sitting in the yard doing nothing.

Saying 45-55HP to run is not right. Regardless how you try to word it. I thought we was talking about the 4430/4440 is good to run it.

Bottom line is you need at least 90HP to pull it. I would go 10-20HP over that for extra power in reserve. A good rule of thumb on how I compare equipment to tractor to pull it.

20 years ago we had a 4440 on a 6601 its a perfect fit and yes its about 130 hp.A tractor 45-55 hp if fine if you just want to turn it over to check it but you may actually want to put some crop in the front.Even a 4440 we killed the engine lots of times when crop got a little heavy.
