Would some kind person(s)explain to me the difference between a live pto and a trans. pto. My plan is to use the pto for a bushhog and occasionally for a post hole digger. What are the pro's and con's of the two. For my use does it make a big difference which one I have?
Thanks to all

Austin , First of all you do not need LIVE pto for anything you will do around your property . Second there is not enough LIVE pto tractors for every tractor buff who wants to have one in his backyard . I have been repairing farm, logging, and construction equipment all my life ,and my hobby happens to be old Ford tractors . I grew up on my Uncle's dairy farm , which has been in the family for over three generations , and is almost 500 acres , He was and still is a diehard International Farmall man . He had H's , Super H's , M's , Super M's , 300 's , 350 utilitys , Cub's , and A's, None had LIVE pto , and most did not even have a three point hitch on them , It was not until the late 60's 0r early 70's when he bought a new 806 did we have LIVE PTO , and THREE POINT HITCH on a tractor together . We cut lots of hay , Bailed lots of hay , chopped lots of corn without LIVE pto and three point hitch for many years , al l you needed was a little common sense and planning when you were cutting or bailing because you could not stop the Bailer or the Chopper when they were full of corn or hay . We also never even used an over-running coupler on anything , but I do know that it is a good idea on the 9N's and the 8N's because the brush hog will push them tractors , I do not use one on my 841's or my 4000's and the brush hog does not push the larger tractors , But I am also not saying it is bad idea to use one .I have over Forty acres myself and have 6 old Fords , None of them have Live pto , I do not need Live pto , and I do not want Live pto , Do know that the Clutch from Ford for the Live pto tractor costs just under $1000 , which by the way is about the best one going , I have installed other brands and they have not worked as well or as long as the Ford clutch , It is one of those you get what you pay for deals . Live pto is and always was a Agricultural Transmission option and is not suited for loader or construction work . Ford never offered it in an Industrail tractor or recommended it for loader use because the the hollow and the small diameter input shafts on the transmission are a weak point prone to breakage with those types of applications , and yes I have replaced alot of them over the years for customers who broke them and burned up them $1000 clutches .The last clutch I replaced was March 2000 on a 59 Ford 861 for the same owner has already replaced it twice and burned it up again . So for what it worth there is some real life expereince and use of the live pto in farming what it was designed for . Thanks Tony Jacobs

If you can afford a tractor with live PTO then that would be what you want. If you want to stay within a lower price range (as I did) you can brush hog quite nicely with a transmission PTO but you really should pop for the $40-60 over-running coupler, assuming the tractor doesn't already have one. It simply attaches over the existing PTO shaft and free spins if your implement tries to drive the PTO while the clutch is disengaged. I assume you don't need a live PTO for post hole digging. You're not moving while you dig so you put the transmission in neutral and use the clutch to apply power to the PTO.

Live is better.

To blow snow, you need live pto.
To bale hay, you'll really, really want live pto.
To brushhog, you'd prefer live pto, but can get by with an over-running clutch. (You NEED that for safety if no live pto.)
For other tasks like digging holes, it doesn't matter much.

Live pto means the pto spins when ever you put it in gear, doesn't matter where your tranny clutch is.

Um, dead(???) pto means every time you push the tranny clutch, the pto will also stop. So, you can't stop moving forward, but let the (snowblower, baler, combine, picker, etc.) clear out slugs. Also, with a heavy brush hog, when you push in the clutch, the hog will continue to spin like a flywheel & move the tractor - so you NEED that over-running adaptor.

Ford actually had a 2-stage clutch on some models as explained in another message, which is 90% as good as a true 'live' pto.

You absolutely want to go for the live PTO instead of the transmission type. The live PTO should have a two stage clutch. Pressing the clutch down to the first stage or stop will allow you stop the motion of the tractor without stopping the PTO from turning. Pressing down all the way to the second stage or stop will halt the PTO. Live PTO makes using a brush hog much, much safer. If you're going to brush hog play it smart and safe and get a tractor with live PTO.

Look on page 5 of this forum. We had a really long discussion about PTO. I learned quite a bit about the subject in that exchange.

Live pto means the pto will spin all the time whether or not the clutch is engaged. In the Ford hundred series, live pto is achieved through a 2 stage clutch: push the clutch halfway down and the rear wheels become disengaged from the engine but the pto keeps on going. Push the clutch all the way down to stop everything. I have an 850 with transmission pto and there have been times I wished I had the live pto, specifically when baling hay. It would be nice to keep the baler going full speed while I slip the clutch to ease through a big wad of hay. I've never bush-hogged or used an auger so I can't authoritatively discuss how much you will need a live pto. There's thousands (well hundreds at least) of folks using those implements with N series tractors that don't have live pto so it can be done and tolerated. It is nicer to have though.
