Lou,

Thanks so much. You confirmed exactly what I thought I knew. The PTO shaft
on this small chipper/shredder has a matching PTO shaft and indent. I guess
I should have just recognized that matching splines and diameters would
indicate a sameness. I think I have a winner... and just in time for some
pruning in the orchard and shredding oat straw for the poultry house.

Appreciate all the responses. I'm sure glad y'all are out there....

Bobby

Your tractor more likely than not has a 540 RPM PTO.  The shaft should be 1
3/8" diameter and have 6 splines.  A 1000 RPM PTO will have 21 splines for
small tractor (below 150hp) application.  You never want to hook a unit
designed for 540 RPM up to a 1000 RPM shaft on a tractor (theoretically you
can if you run the engine at about 1/2 speed, but you better be sure you
don't go above that).  If you do, you are going to have all types of things
flying apart, and it won't be pretty.  If you hook a machine designed for
1000 RPM up to a 540 PTO shaft on the tractor, you won't get the speed or
desired effect out of the machine.

The Ford most likely had a 540 RPM PTO.  It may have a 1 1/8" shaft.  If
that is the case, you will have to change the yoke on the end of the shaft.
There really is no way to hook a 540 up to a 1000 or visa-versa, unless you
use adaptors and/or someone changed the yokes on the end of the shaft that
hooks to the tractor stub.  The shaft from the machine should fit on your
tractor snuggly, without slop.

Howdy gang,

Happy new year to you all.

Have a chance to buy a very sharp PTO driven Chipper/Shredder for the farm.
Very nice little unit and a great price. problem is I don't have a great
deal of background knowledge about PTO's. I know there are two standard
speeds but how does one know what goes with what if it isn't clearly marked?
I have a JD 1070 and it's PTO speed / rating is clearly marked in the
manuals. No problem there... but this little shredder unit has no PTO
markings, nor manuals. is this a dumb question or is there something I need
to know here? The seller hooked it up and ran it for me on an ancient Ford
but I have no idea what the Ford PTO speed was, or if it is the same as
mine.

The obvious question that I truly don't know the answer to: are PTO ratings
critical and what would happen if they were mismatched? OK guys, I'm humbled
and ready for some schoolin'.  All answers appreciated.

Bobby
