Hooking up PTO w/ Engine Running

[RoyJackson]

luckilly all my old fords have lever engagement. no new fangled push button or telepathic engagment options that some of you guys with new tractors have..

I disconnected the telepathic engagement on my 4400 after the wifey took out an insurance policy on me...

ya know.. a while back my wifey doubled my life insurance policy..

lucky for me, about the only thing my wife is dangerous towards is a pile of salted corn chips, or a tube gate.. I think she enjoys backing into them.. as she's so good at it and practices often

if I'm not on later.. it may be because my wife read this thread..

This is the thing....... you get into the HABIT of doing something thinking its safe, and it may well be. Then you use that same old habit on a DIFFERENT machine AND the old habit is NOT safe on this machine.

That is exactly as I reported. This thread made me rethink my habits, based on experience and changes in engineering. I guess they save a good bit of money by eliminating the two stage clutch and putting the electric clutch farther down the line. I can't see where it is better for the operator, or the operation.

Also, they seem to have put a brake on the PTO. (To protect me from what?) The brake seems to be engaged whether the tractor is running or not, key on, or off. I cannot turn the disengaged PTO shaft by hand, and so, must either start the engine and bump the PTO switch (hit and miss, mostly miss), or manually rotate the implement's shaft, to get the splines lined up. It busts my poor fifth lumbar disc to get this done. Literally, a pain in the @$$.

I plan to cut a thin ring from an old female PTO coupler and braze a handle onto it to make a wrench to rotate the PTO when it's disengaged.

OR ad an ORC to th e pto if you have room.

past that I've always found a long srewdriver ( 1'+ ) thru a yoke will turn a shaft even on a batwing..

I doubt the engineers distrust the mechanisms that must fail for the PTO to start spinning on its own. More than likelyhood this is about liability.
...

My father was an electro-mechanical engineer and was one of the designers of the General Electric Elec-Trak tractors back in the '70s. He was also a **** good machinist. His mantra was to shut the machine off before messing with any rotating parts. Didn't matter if it were the pulleys on a lathe or milling machine, the blades on a mower, or the PTO on an engine. He's still alive and uninjured today at 77 years old. And I plan on beating him in pushing the max age of the men in my family.

The point is, a smart engineer ALWAYS distrusts the safety mechanisms simply because you never know when just the jarring of the shaft as it fits onto the PTO stub may be enough to pop the lock off or re-engage the clutch.

I'm not trying to be disrespectful or insulting, but if you're in such a hurry to hook up that you can't take the time to turn it off and restart it, then you're already in the mindset of not taking enough time to ensure the PTO lever is fully disengaged before hopping out of your seat.

And I'd sure hate to lose any of you folks over a simple mistake.

the reason engineers have to mistrust stuff like that is because 1, when they designed it.. it was good, overbuilt and safe like a rock.. then some dern bean counter figured they could save a penny on every 5000 units, called for a value-engineered re-design that just barely makes it past warranty 80% of the time.. uses flimsy parts, is designed to be repalced or fail, and in general, is probably brittle.

ask any engineer if you don't believe me.

bean counters get more input into the way something is built than we, the engineers do. BTDT on jobs I've engineered.

Noah, build an ORC.

Right, Lord. What's an ORC?

Over Running Coupler?

(I had to look it up)

i hate getting off tractor while it is running. i do get off tractor while the engine is running, but i do not like doing so. and because of this it normally kicks in to check gear out, brakes on, etc...

but i still have managed to hit something that caused the tractor to start moving while just getting off the tractor.

==============
with above aside, many times, it is just me and no one around. and those inital 2 arms for hooking up implements i leave the engine running while getting them hooked up. after that engine gets turned off.

to many times i need to raise / lower arms just a tad to get things hooked up. and there is no physical way to get things hooked up with a large size crow bar plus a cheater bar on it. or use of a jack. so not much of a choice. but keep tractor engine running, so i can raise and lower the arms. i am still skiddish though, of keeping body in a place were i might atleast fall backwards if tractor begins to move on its own.

hooking up the PTO or getting under tractor engine = off.

Over Running Clutch...

We TBNers are adding too many unfamilar acronyms, IMHO
