540 PTO extension

[vangreenacres]

My first post. Bought an acreage last fall and purchased a 4010 that has been great so far. Need info for two things on my 4010.
First: Went shredding Saturday and things worked just great until I bumped 'er into 2nd gear. About 15 minutes after doing so, I twisted my PTO extender (see photo). Where can I find another one of these? I googled "pto extender and get only a male/female ended part which I don't need. This is about 5.5 inches long and has a tightening bolt in one end to expand it into the PTO. Since I have a front-end loader there's an extra box on my PTO that makes this extender necessary.

Second: I noted on the gauge a line with "PTO." Does this line on a 4010 mean the Maximum for PTO use, or does it mean to "set your rpms here," when using the PTO for maximum torque." Have asked a half-dozen people over the age of 60 and I got a half-dozen different answers to this question.

Help with these two queries would sure be appreciated!

Hi Vangreenacres. By gauge I assume you mean tachometer. The line marked "PTO" indicates the speed to which the engine must be revved to achieve the requisite RPM (usually 540 or 1000) at the PTO. I'm sure that someone will be along soon to help with the extender question. Good Luck.

Thanks for this tip. I'll be sure to share it around, though I'm the only one around here with a 4010 anymore.

Maybe cut this down?

Would appreciate some pics of where this PTO extension is used. Looks to have been some serious torque to twist it like that..

When you kicked it into 2nd gear, do you suspect that overloaded the extension shaft?
What is the shredder brand/model?

"Requisite" is the debatable part that probably leads to getting a 1/2 dozen different answers.

Thanks for the input; will try to get some photos tonight or tomorrow along with shredder brand/model as you requested. Had the machine in 2nd gear for about 10 minutes and suspect the overload came when I hit some heavy thistles. I did not have the rpm's up to the "PTO" mark on the tach (as evidenced by my lack of knowledge as to what the line meant) but was close to it. What makes this extension unique (meaning I can't find it anywhere) is the bolt up the center that "expands) the open end to fit snugly into the PTO. See additional photo.

Thanks for this lead--it's the best alternative I have seen. Will send it to my brother-in-law for his inspection--it was his extension I borrowed. I'm guessing if I don't find the exact duplicate that I'll have to give him my wife back (his sister).

I believe that, that style of extension was used with the farmhand brand loaders when they used a pto pump for the loaders.
i have no clue where you could find one now.
Good luck

You are right, it is a Farmhand. You got me thinking--maybe I should add another thread in the "attachments" section. Surely, someone else has a similar problem and a solution to go with it.

I haven't seen one of those in many years,
would it be possible to use one of the newer style long extensions.
Put it on your tractor, slid the pump on as far as possible and have a usable shaft extending beyond the pump?

It would move your pump back several inches.

So the OP needs a male to male shaft?

Will see how far I can move the pump back--thanks--this may be the only solution. Seems that few folks remember this item and no one has seen one for years.

Good luck, I've used the extensions on my 574 as it has dual shafts, 540 and 1000.
I have a hydraulic pump that wouldn't fit without the extensions and I have had a couple snap off from the length and vibration at times.

As has been spoken before "picture is worth a 1000 words''. Please next time you post a question about the 4010 please state it's an 80 HP rowcrop model not CUT model. It appears ruffdog has your broken shaft problem solved. Now to address the reason the shaft broke. The slip clutch on the rotary mower is stuck causing shaft to break when some obstruction was encountered. I'll suggest to free up slip clutch before something inside tractor gets destroyed!!!

 

[ruffdog]

Well...sort of...A solid shaft would be MUCH stronger than the hollow expandable one the OP broke. The expandable version is needed so it stays in the pump while the cutter pto is attached to the other end. Not the safest situation.

Will a splined shaft slide through that pump? Appears it will from the pics.

 

[Tx Jim]

Yes I think a solid 6 splined 1-3/8 shaft will slide through pump.

 

[beenthere]

Thanks Tx Jim. Sounds like a better solution then.. with a better pump support than shown.

That, or get the pump moved to a different location than on the PTO.

The part that was tore up was not a good solution (obviously) to drive a rotary cutter. So wouldn't go that route again.
