About ten days ago, I was baling and ran a 3-4" tree branch into my NH BR780A and tore up the wind guard. Got the parts in and repaired it--no problems.
Now for the interesting part.
For the last couple of years, I had a pretty loud rattle when I was first starting a bale. Once the bale was started, the rattle went away. Things rattling or knocking worry me. I figure something is about to go kablooey.
Looked and listened but just couldn't find the source. Tried starting bales fast, slow, in between--nothing made a difference. Talked with a couple of service guys and got suggestions such as it was a bearing going bad, a roller had loosened up or broke, chain tensioning was bad, etc.
Couldn't find anything so I figured I'd just keep going until whatever it was broke. Then I'd know for sure.
Yesterday, I was baling for my neighbor. First time since I repaired the wind guard so I was listening for anything banging or hitting in case something was mis-aligned or I had missed some other damage.
First bale started--no noises. Good. Second bale--no noises! Even better. Third bale still no noises. Then the light bulb went off--no rattle!
Finished baling and not one rattle. Whatever was rattling must have been in the wind guard.
Don't get me wrong--I'm not recommending tearing up equipment to find and fix a different problem, but sometimes we just aren't looking in the right spot to find the source of a problem.
