Tractor PTO (clutch?) problem

steve terplak · Jul 23, 2015

Hi guys,
I have a Landini 105 Vision.
I was baleing today and I heard a rattling sound behind me and noticed that the flywheel on the baler had stopped turning, so i turned the pto (electric) off.
At first I thought it was something with the baler,nothing plugging it up, flywheel turned easy, shear bolt is in place.
I tried it again and got the same clacking noise.

There is something not right with my PTO.
The shaft turns easily by hand with little resisitance, when I do this it makes a clicking noise, this is not usual. When I turn the pto on and off, it spins and stops when I want it to, but it will not turn a pto.

Is there something broken on the shaft (perhaps I have one of those reversabile 1000/540 shafts and the splines on the inside of the shaft are broke, or perhaps it is a PTO clutch.

HEre is a picture of the back end of the tractor. I apologize if it is upside down. What happens if I remove those three bolts?
Is this a PTO clutch problem?

Thanks in advance for any direction.

Hi, I don't know anything about a Landini tractor but on a CIH tractor the PTO shaft is run from the clutch pressure plate. The PTO splined shaft goes into teeth on the pressure plate. The pressure plate teeth are softer material and eventual wear out. The first symptom is a rattling by the clutch housing and eventually the PTO shaft will turn with no load on it but will stop when connected to an implement. So investigate if the clicking noise is coming from clutch housing area.

Good luck

Where is the clutch housing area and what (briefly) is the replacement process?
Thanks

Hard to tell from the picture but is the seal missing from around the PTO shaft? Looks very rusty brown at the base of the shaft.Is there side to side play in the shaft?Bad bearing?
With the tractor engine off and the PTO engaged, can you turn the shaft? Might give you some idea where it is slipping or broken.
Good hunting!

If you have to ask that question, I think it's time for a mechanic and a thick wallet.

I have a tractor with the 540/1000 PTO. Mine did the same thing when 540 was selected. The 1000 RPM worked. Opened the transmission and my problem was that the 540 gear stripped. If neither work it could be the driving gear on yours. On mine I can not get a replacement 540/1000. They make only a 540. My deli mina is pay $400 for the 540 and lose the 1000 or keep the 1000 for free.

Vision has shiftable PTO speed option and a ground speed pto setting, if I recall. I can't remember if the ground speed has a neutral position but check if it was knocked out of the correct position, the lever is to the left of the seat on the floor I think. Been 6 or 7 years since I was in a Vision.

I guess more than one of us thinks alike but only one of us was bold enough to flat out say it. Some days it's better round here to just smile and move on!. Been doing that a lot recently round a few tractor forums with some mechanical posts.

I got customers come for updates on tractors, the supplying parts guy just tells them get your mechanic to "pop" that part in and your good. they come here with the part and tractor, then say be back in a few hours for it. I kinda tell them a brief description of "Pop that in" may take 14 to 20 hours plus, depending what else I find wrong or what don't come apart like it should. Oh the joys of being a mechanic. depending who calls some days customers are just an occupational hazard L.O.L .

Hey guys, thanks for the responses...
Think I found the problem...
I removed the three bolts around the shaft and found a broken PTO shaft.

Here are two pictures of what I found.

When I pulled the broken shaft out of the way, the inside seemed to be the concave reverse of a PTO shaft, I am assuming that this is what is driving the exterior shaft...

In the operators manual it gives the option to replace the 540 shaft with a 1000 rpm shaft and it shows, after removing the three exterior bolts, four bolts holding the pto shaft in place...I do not see this on mine...

Any thoughts and ideas?

Also, what could shred the shaft like that?

Thanks,

Hi
I can't really see a good angle on the shaft picture, but it looks like the splines on the 540 Male (6 spline) are worn. Usually the area where the Push pin to hold the female coupling on, is a shallow rounded groove less that 1/2" diameter. looks like yours is worn maybe an inch long into the splines. It could be the coupling slides back and forth and fatigued the shaft when it hammers at the end of the play, somebody did something stupid before you got the tractor and bent or damaged the shaft somehow, or it's had a real heavy pto implement shaft hung on it and it cracked , I had a guy pull a pto shaft out of a Belarus tractor with a huge slip clutch hanging off an old style pto pack. With a used tractor and all that good fun you never know what really happened before you got it.

That might make some sense. I will have to give it a better look later...also before we got it, it had a custom side hill mower mounted to it...that may have been the heavy pto...
All it has ever done here for a few hundred hours is bale small squares and pull discs

I apologize for my question...I am sure that some questions seem stupid but I am just trying to get a better understanding of what could be the problem and how to approach solving it.

Robert Major · Jul 24, 2015

Hi I guess if that tractor was maybe with a custom mowing outfit, maybe you are better off not knowing some of the history L.O.L.

The other thoughts on that shaft could be how loose was the coupling when pushed together, if you had a lot of up and down play due to worn splines on the tractor shaft and maybe baler to that could make the couplings wobble/wear at 540 and fatigue the shaft, or even just that shaft wobbling if it over hung the end of the splines to much with that groove worn longer. With a new tractor shaft the 2 should slide together snug and have very little to no wobble or end float ( forward rearward movement) with the lock pin in place depending on machine tolerances from the factorys.
