Hi folks,
I have an ancient and decrepit rotary cutter that was included with a previous tractor purchase. It has been patched and welded all over, the PTO shaft guard is mangled, and I just discovered that there is supposed to be a locking mechanism on the PTO shaft yoke. I discovered this after I attached the cutter to our new Kubota L3010 and cranked it up - and the shaft came off and flopped around in a rather disturbing fashion /w3tcompact/icons/shocked.gif. This never happened on the old Yanmar we used before, I think because all the rust on the PTO stub held the yoke on by friction. I have temporarily fixed this problem, but I now notice that there is a tremendously loud thumping noise whenever I engage the PTO. It sounds exactly like the blades are hitting the housing. I didn't dare peek underneath while it was operating at speed (don't even want to get off the tractor with it operating), but when I disengaged the PTO and hopped off to look, I couldn't hear or see anything out of the ordinary. Is this sound normal? I don't remember it from the last time I bush hogged a couple years ago... It's going to cost me at least $50 in parts from TSC to make the yoke not slip off, and as I said before this implement has definitely seen better days - should we just get a new rotary cutter?
Thanks for any advice!
