New Holland 640
I've been looking for a round baler and came across a New Holland 640 that's in my price range. I can't find much information on this online and was wondering if anyone knew. The add says it will do 4x4, 4x5 and 4x6 bale, but what I've found says it's only 4x5. Is it a variable chamber or not? Also, would this be too much baler for 50 PTO HP? What is AutoWrap? I'm new to round balers so any help is appreciated!
