PTO Extension

[barnman]

I recently mounted a Pat's Easy Change system to my tractor - by doing so that moved my brush mower approximately 4 inches farther away. I now need to extend my pto shaft which leads to my question of asking for recommendations of the best method. The best would probably be to purchase a new drive shaft but the cost is currently prohibitive. My next thought was to replace with longer shaft tubing, but when I removed the plastic guard I found that my tubes are welded to the u-joint assemblies so that will not work. That leaves me with two ideas - 1.) Purchase an extender for the drive shaft or 2.) weld a 5 inch piece of identical sized tube to the female side of the drive shaft and overlap that weld with two lengths of angle iron to strengthen that future weak spot. I have been advised by friends who do not know any more about this than I do that the pto extenders are probably just a weak spot waiting to cause a problem.
Ideas - experience - and suggestions will be very much appreciated. Also, because of my age and back condition, I really need the easy change system.
Thank You..........

Take a look at these PTO Extendes:

I hate the idea of shaft extensions but recently the topic came up and somebody suggested putting the extension on the implement end of the shaft. This cannot be done on every machine but the idea has merits and could mitigate some of the potential problems associated with extenders.

You don't need angle over the welds! Just V both pieces out, lay them in a piece of angle to hold them in alignment and weld away...

I've done this MANY times and my 70hp tractor doesn't break them...

Here's one I'm extending,

How do you get them straight without a lathe or a guide?

By laying and clamping the pieces on a piece of angle iron. The shape of the angle iron will get everything centered and straight. If the two pieces of tube are the same diameter. Otherwise you'll need to play with shims but still doable.

Another possible option is to purchase a overrunning coupler... they are not that expensive & they are designed to use with brush mowers (etc)... & most will make up the 4" you need. Your NH 1715 doesn't really require one for a brush mower but it definitely won't hurt it either; I use one on my NH TC40 with our chipper... again not required but doesn't hurt my internal PTO brake not to "have" to stop the 200lb flywheel.

My neighbor purchased an overrunning coupler after I gave him my Pat's easy change system & he installed it on his JD, he saw the one I use with my chipper & was sold. He has zero issues with it on multiple pieces of equipment with multiple PTO shafts... Just another option...

BTDT. Works well.

I see you STILL have reading and comprehension problems... ha ha ha

Thank you for the reply - My shaft is square so it would be easy to align the pieces - my thought with the angle iron was to use 2 pieces so they would work like a sleeve over the weld. It is nice to know that your welded extensions work fine.
