Have you considered simply taking the belt off of your chopper when you don't want to run it? Would that cause a problem? That would let you have your power when you needed it, and also let you keep your chopper...
there is a guy around here that grows corn under a circle (no, we dont grow much corn around these parts...gotta get on up toward Dalhart, TX for corn), and he had a combine with a straw spredder (whirly bird). The spreader didnt sling the stalks very much..
No we don't run cattle on the stalks after we cut, we just disc them down. And the reason I was thinking the whirly birds is just that the straw chopper to me takes so much more hp to turn it vs the whirly birds.
I know in corn there isn't much trash coming through thats why I was thinking the whirly birds would work.
If I was just to take the belt off and roll it forward I think there would be to much trash in the middle. but it is a thought.
Im just trying to save fuel and possibly run alil faster is the reason I am asking. Thanks for the comments.
