PTO shaft safety project

[8100]

How about a alloy or metal collar with decent bearings and grease point attached to plastic pipe instead of the daft things about now .Cost more yes but could be rebuilt and reused on replacement plastic pipe etc

I don't attach shafts when the tractor is off and it makes me cringe just thinking about attaching one with the engine running.

What's that based on? Is there a higher chance of the pto mysteriously engaging than the roof falling in on the shed you're parked in? I trust you live in a bungalow to avoid those damnable stairs.

Our deere (22 years old now) applies a brake to the pto whenever the engine is running and the pto is not engaged. Means you have to stop the engine to hitch up except where the implement shaft can easily be turned by hand.....

You do have a point. Pto engagement systems should be designed fail safe. It's hard to see how ours can be accidentally engaged when you need to lift and turn a knob.

I wouldn’t ever connect pto whilst tractor is running. I would be move concerned in the hydraulics misbehaving than a random PTO start up, but for the sake of simply turning a key why take the risk? All to loose nothing to gain.

I had MF tractors years ago 3000 series , 61s and 62s series. Then 2004 got a Deutz Agrotron, still have a M620. All had a free running PTO's, never locked. Started driving a John Deere about seven years ago , thought then how stupid having the PTO locked when the engine is running, having to stop engine or put in neutral to attach PTO shaft.
Still think it's stupid, much safer with a free running PTO.
Just my opinion.!!!!

Had a poor electrical earth on my tractor cause the pto to engage on it's own... wouldn't want that happening whilst attaching PTO shaft.


I keep thinking that machines should somehow have PTO shafts integrated inside the drawbar/frame, no need for the plastic guard then.

Link arms are always a pain on trailed kit maybe they should be folding, like front links, or have quick release on them so can be taken off.

Just wouldn't do it. PTOs are engaged by switches these days- electricity. In some ways they are less safe than a lever you had to pull to bring the PTO clutch in. Either way I still wouldn't do it with the engine running I don't think. Shaft comes alive in your hands or engages the implement behind etc. Of course, you have to contort yourself into all sorts of positions to be able to get a PTO shaft on sometimes. Even if the tractor itself got knocked out of park or went into gear etc you are going to have a bad time if you are twixt it and the machine behind. Easily done too, man jumps in to machine to move it a fraction and doesn't know you are there. Dog/child etc knocks off handbrake (if it even worked in the first place).

Pto shafts are pefectly safe if you dont go near them when running

A bit of a reminder or eye opener for any younger folk reading this thread....

I read this thread yesterday and posted on it

Today I went to remove a Binderberger saw bench that I coupled up on Wednesday. Cannot get the tractor end pto off for love nor money today. I reckon I jinxed it

It's a Eurocardan shaft with the push button. That seems stuck. Have stripped off the tractor's steel surround guard and can tap the button 'open' with a drift but it still won't move. My index fingers and thumbs are sore tonight. I think I'll try a ratchet strap from the yoke to a shed stanchion and get someone ratcheting while I tap the button down into the 'open' position. A waste of two hours today and still not done

God knows why it's stuck - all our ptos are relatively clean and tidy and greased and it slid on and clicked ok when I coupled it up
