I always look at this question like this, how fast do you expect to travel? A 50 hp tractor will easy enough chop one row of corn at 1-2 mile per hour, but a 80 hp tractor might let you chop the same one row twice as fast. I chop using a nearly 50 year old 100 hp tractor pulling a 2 row head , if I see anything more than 3 mph , it would need to be a poor crop of corn. Thousands and thousands of acres of corn were chopped with one row harvesters pulled by tractors turning out less than 60hp. Just takes longer

Don't remember what model ours was but it was the flywheel type and never chopped much with it, just daily for direct feed to cows and it was single row and pulled it with a 28 horse John Deere B, The cylinder type I believe takes more power as the way the one was that my uncle had that I ran.

I ran a 707 3 point hitch single row with a 38 PTO horse power tractor for years, never bogged down.

There were a few NH 717 choppers in our area, we had a Super 717 with the 9 knives, one row corn head, pickup and direct cut head. We ran it with an IH 684, neighbor next farm east had one as well and he had an IH 574 and later 684 another neighbor used an IH 656 on his 717.
The Super 717 could handle a two row head but as Bruce said required a 100 HP plus tractor.

How fast, and how fine a cut? Put many tons through a 717 and later 718 with 60 hp. and one row. 2 rows , 90 hp will work, hills need a good chunk of tractor if you are pulling the wagon behind the harvester.

We have a S-717. We tried running it with a Case 1294, 56 pto HP, and it was more than it wanted. We run it with a 966 now.

How many knives are on the cutter head? A 9 knife machine will take more HP that a 6 knife machine.

75HP should be adequate under most conditions. Hopefully with a good slow low 1st gear.

I'd want at least 70 HP. Back when guys were running 1 row machines with 45-50 HP tractors corn silage was only running 12-15 tons per acre. Really good corn silage will easily run over 30 tons per acre in current times. As others have said a good selection of slow ground speeds will be important if running around 60 HP. Most newer 1 row machines such as NH 718 will take 80 plus HP no problem.

717 or Super 717? If it is a 717, you'd better stick with 75 hp or less. I had a Super 717 and they are built heavier than the 717. I used a 1650 on a 2 row head and it worked pretty good. My 1955 would take out the first u-joint right off the tractor with regularity no matter how careful I was. I would go no bigger than an 1850/4020/806 size tractor on a Super 717.

With a 75hp tractor on a one row chopper you can go a whole lot faster than it will be comfortable trying to stay on the row. Any 55 hp tractor will handle one row unless you are trying to pull a wagon behind the chopper on hilly ground. In days gone by we chopped many, many acres of corn with an 88, and then a Super 88 with a two row head on a NH 800 chopper pulling the wagons on the side with another tractor.

One other thing. Check out the shear bar adjustment bolts very carefully. Make sure the adjuster bolt threads aren't stripped in the chopper frame. If they are it is a BIG time repair.
