PJ Brown: For the most part your question wasn't very well answered. You did ask the minamum hp for the NH 782, and really buickanddeere was the only one to do the question justice, by asking more questions. Those New Holland with separate cutter and blower don't require the amount of hp many harvesters do. My answer would be somewhere between 55 and 100 hp depending on how much and how fast you want to do the harvest. There is a huge difference between a dull poorly adjusted cutterhead, than a sharp fine tuned cutterhead. If you want to run it poorly adjusted and dull, it's going to take a lot of hp to make up for that, probably as much as 40%. I filled two 24' diameter tower silos, one 50' high, one 70' high on average 3 fillings per year. Fill both with haylage in spring and one with corn in fall. Did that for a couple of years with Farmall 560 diesel and two 40 hp tractors. One 40 hp pulling wagons, the other on blower. Then I added a 656 diesel and 504 gas to fleet. Then I traded 504 off for a 1066. Frist event 1066 destroyed a brand new NH 780. Harvester hadn't filled a silo. Traded the 780 for an 890. 1066 and 890 would put up a 20' wagon load of silage every 10 minutes, and the blower at the silo, forever became a bottleneck, even with 100 hp on the blower. I can name you numerous farmers that have filled silos for 60 head of cattle, and done it for years with 50 to 60 hp and yes on a two row head. You can slow the feed on that 782 down to match the smaller tractor, and if you keep your cutterhead and blower well adjusted and sharp, you can get along quite well with 50 to 60 hp.
