H7220 mower noise

My moco has been making a strange noise, more like a bang here lately. It only will do it while down and mowing. It has gotten worse with intensity, as in now it is noticeable in the tractor. I have replaced the u joints and upper roller bearing on the gear side a couple of weeks ago. I thought the bearing was the issue, but after taking it out it was fine. I already ordered the new one so I went ahead and put it in. I reset the roller gap on both sides. The cutter bar does not seem out of time and when it jumps or bangs it does not miss any hay, which has led me to believe it was the rollers. But I'm stumped, any advise would be great.

Background:

I bought the mower new in 2014, the problem seemed to start last year but has gotten progressively worse this year.

I have tried slowing down rpm and speeding up seems to do it either way.

Also will do it in extremely heavy or thin hay.

Will not do it unless mowing, u can run it up and it will be fine.

Gleaner K Bean setup

So that K that I bought earlier this year is set up for corn and all I have are soybeans this year. I'm trying to get all the adjustments and measurements and all that other jazz figured out to harvest beans soon. I have both The Operators manual and the service manual to help me figure it out but that only helps if I know all the terminology and what the heck pieces are as I've never in my life had a combine and don't have anybody to teach me. Can somebody give me instructions on how to get this thing set up for beans? my time frame is kind of limited because I am getting married in less than 2 weeks and will imagine the beans should be about ready then too. While she is very understanding and helpful with everything on this property, she even wants me to get one set up for her to drive, we are getting down to the nitty-gritty and need to focus more on the wedding preparations.

Bush Hog 2615 Legend

I have an older 2615 I'm fixing up and the drive shaft needs replacing. It has the two piece shaft like this; I do not see why I couldn't replace it with a one piece shaft like this one; http://ift.tt/2ygWKtC
cutting out the support with the bearing in it. Just making sure before I ordered stuff.
Thanks

NH 7320 problem

This is my 1st season with a discbine. Today it stopped cutting. It spins the flails and the rotor on pto side but not the other caps. When I spin the opposite side rotor by hand the 6 caps move together but not the pto side. Anybody had this issue?
