My AC170s/175s are going to be lonely this spring, if I can't get this NH488 Hay Conditioner Mower fixed? (My ID photo above shows my AC175 pulling the Haybine.)

Now our old NH479 broke, and I found another newer NH488 but unfortunately, both rollers rubber groves were worn off down to metal? I'm trying to remove my old NH479 rollers to replace the bad 488's, but having some issues? Ha!

Does ANYONE have a 'how to' service manual with procedural steps to remover rollers?

I'd be glad to pay for those service pages?

Does anybody have experience on changing out those rollers?

Thanx for any suggestions, or names to contact for help?

Seems to me you have to take the header off and they come out the front. Don't do that till you check with someone that knows for sure. I had 489 that the rollers came apart but I traded it for a 617 three pt disc mower. I did change the steel roller in a pt7 heston one time by myself. I was younger then. Took rubber roll out first and then bottom steel roll. Both came out the right end of the machine if my memory is correct. Bill
