Ripley, Ontario Canada | You can drive a chopper with as little as 75 hp, or 800 if you want. If you get a little 717 NH 75hp will drive it. It all depends how much you are trying to put through and how fast. The 717/770 choppers are really 7-9 feet of stuff (this is in good hay that would give 5+ 4x5 round bales per acre) the 782/790/892/900 choppers will take 12 to 15 feet nicely, bu you will need to up the hp to 120-150 to make time.
That said if you have a light windrow of weeds the power requirements and the width you cut can be adjusted. Also how fine do you have to chop this if you just blow it on the field. If you can take 1/2 the knives out so you get 3/4 or 1 inch theoretical length of cut, the throughput will go up and the hp will drop a bunch. | |

Round baler hp?
