I have a New Holland Twine small square baler (5060) that I bought new 3 years ago. I have baled over 10,000 bales of Bermuda hay without any problems but I was wondering when should I have the blades sharpened or replaced. I suspect I'm already behind the ball but the bales are very uniform and compact. I've looked at the manual to see what is entailed in sharpening them but it is not very clear when or how to do the job. Who ever writes NH's manuasl does make it easy for the rancher to do it himself. I'm sure it is not that hard once you do it but I reluctant to just start taking parts off without knowing what I'm doing. Dad and I always had John Deere's before and they weren't that hard. Anyone know what dealers charge for sharpening blades? Are the new blades throwaways or can they be sharpened. Any help would be appreciated.
