3-Point Hitch Rear PTO Noise

[CajunCurr]

With no load on it my makes a little noise as do most tractors as they are make to have a load and work that way other wise you hear at idle the gears load and unload rapidly which would be the noise. If I undestood your post it don't do it with a load? So why would you turn it on with nothing hooked to it?

I just cleaned it up and was getting ready to put it away. More or less just messing around with it. If it was just gears make a slight chattering noise I would say no problem. However that is not it and maybe I am not giving the best description of the noise. It sounds like the rear end is being hit with a ball pein hammer or like when a car lifter gos out. The noise is louder than the engine and can hear through the entire range from idle to full throttle. It never did this before so why now, wear? I have not reconnected my mower to teat it, but I plan to do it after i get it back.

Running my B3030 rear PTO at idle with nothing attached creates just a slight ticking or tapping type sound as the shaft spins. Nothing loud at all.

Thanks. That was how mine sounded up to now. How many hours do you have on yours?

130 hours.

Correction - 140 hours. I have never used the rear PTO for anything yet but the person I bought it from did. I figure a rough cut mower will be my first rear PTO implement.

Thanks for the info. I really think a bearing has failed and it nothing really serous. I am borrowing work's bore scope to look at PTO gear from the oil fill hole. I don't know if I will be able to see anything.

Not sure how relevant this is, but see the following thread for PTO noise I experienced on my brand new L3700:

I called multiple dealerships and was told that "they all do that" . The explanations in the thread also make a lot of sense. I recently purchased a Land Pride finish mower (which has a lot more rotational friction than the land pride rotary mower) and even at idle with the PTO engaged it does not chatter/rattle at all.

Thanks Steven. The noise comes when nothing is attached. I just need to get my tractor back and start testing it. If it goes away with the an attachment connected, I guess I will just have to wait and see.

I don't know if the mechanicals are the same, but my 2010 L 3400 HST had a "knock when PTO was engaged with no implement on last fall. Dealer said it was not unusual for this and to run it. I have a 72" rear mount blower I us all winter and blow 3-5 times a week with depths 4 to 12 inches each time. I blew snow all winter and the unit does not make a noise when attached to an implement. I worked all winter hard with no problem, but still knocks with no implement. I for one will keep running it. It's on record at the dealer.

firemech,

Thanks for the info. That sounds like what mine is doing and the dealer told me the same thing. He is giving me a work order as receipt. I plan on cutting this weekend so I will see. I'll go along with what they say and keep and ear on the noise.

This sounds like your over run clutch is clicking in and out because there is no load on the pto shaft. Try hooking up to a mower or something with some cintrifigul force, engae pto and run up to speed then shut pto off, you will probably here the same noise. this would be normal. Clicking noise while running the mower would be grounds for concern.
