Snowblower on B21??

[devildog1]

It may be normal if you haven't ran a snow blower on a three point hitch before. What I mean is they are quite noisy. I had a Lorenz behind a Old Oliver Super 55, it was a bit quieter then the front snow blower that I had on my BX23. Now I run a LA2674 Kubota behind my 3540 and I do have to say it's the quietest of the three.It seems that you checked all fluids and chains, did you check the PTO shaft to see if the universals are not binding or worn? Best of luck to you.

I'm wondering if the gear box, being new, will settle in after a little wear. Try putting some hours on it.

I don't have a B21 but I did recently use my PTO for the first time and it was completely silent. I know that doesn't help you but you may want to find out from a dealer if there is something about the B21 that makes them wine or if something might be misaligned instead.
