Thanks. I forgot to call Bish yesterday and they're not open today so I figured I would ask on here.
Somewhere I had read the lateral tilt made the feederhouse opening too tall to be adapted to a Deere head without essentially ruining the Deere header for a Deere combine.
I am a fan of corn heads that come as close to leaving the corn stalk standing as possible. I am going to try grinding knives down on a few rows of the Challenger head and see how it works this year, but if a Deere head with fluted rolls leaves more corn residue standing than I can get out of the Challenger, I'll probably switch in the future.
In the meantime, we have three John Deere heads as a result of preferring different heads to our harvesters and if I could move those easier now that I have a combine, I would be inclined to buy an adapter right away.
Unfortunately for me, I realized after Kevin answered my "will it NOT chop?" question he probably meant you could get it without lawnmower blades. I would imagine he didn't mean you could leave the stalks standing like a old John Deere head with tapered fluted rolls.
