PTO shaft spec info needed

[LD1]

Well, I need a PTO shaft for my flail mower that I bought if those of you followed that thread. The guy I bought it from basically gave me 1 and a half PTO's. The flail is 1-3/8 6-spline on the gear box. The half PTO he gave me has a 6 spline yoke. The whole one he gave me has that on one end and the other is a round bore.

Since PTO's can get pretty $$$, I am trying to figure my cheapest route.

Bacically I need 1-3/8 spline on BOTH ends, with a length in the 24" cross-cross range. But that can vary a few inches either way.

I am not in a big hurry, the PTO off my bushhog will work. It is the right length and ends.

But I was considering just swapping the round bore end off one of the PTO's he gave me for a 6 spline end.

So my question is on the yokes and u-joints. What are the differences between 6n, 12n, 14n, 35n, 44n, etc. I cant seem to find a chart or anything that explains the differences. So if any of you all know, or have a link, it would be much appreciated.:thumbsup:

EDIT: also, is there any applicable difference between the PTO shafts with the rectangular bores vs the triangular bores? Can one handle more load than the other. Everyghing I currently have is the rectangal bores, but I see a lot of newer stuff has the triangular bores.

Those numbers are the G & G (a manufacturer) series numbers to designate the Hp. range of a specific PTO size. Other manufacturers use similar ratings. They are listed as a certain Hp. @ 540 RPM:
6N = 16Hp rating
12N = 25Hp
14N = 35Hp
35N = 58Hp
44R = 80Hp

The triangular profile tubing type, Bondioli and other manufacturers, usually go by series numbers from 1 to 10 commonly:
Size 1 = 16HP @ 540RPM
Size 2 = 21Hp
Size 3 = 30HP
Size 4 = 35Hp
Size 5 = 47HP
Size 6 = 64Hp
Size 7 = 75Hp(This one is pretty well obsolete)
Size 8 = 95Hp
Size 9 = 120Hp
Size 10 = 145Hp

Thank you :thumbsup:

Very good information there.

I did find what I was looking for though and an EXCELLENT reference.

Pretty much has the info you gave me plus different u-joint sizes and other things.

Looks like I will be needing a series 4, or a 14N.

Well, I just ordered a PTO shaft from CCMachine out of tennessee. :thumbsup:

I think at one time they were a sponser here because I remember seeing their logo before.

Very nice and helpful to deal with over the phone. The guy that was their PTO "expert" was out today with high bloodpressure. The guy on the phone gave me his home # some I called him. He was VERY helpful, even with part numbers from home. He gave me the correct part number to call back to the office to order, which I did.

Cheapest place I have found period.:thumbsup: 1-3/8 6-spline Quick disconnect on BOTH ends and 48" long collapsed for only $93.95 plus shipping.

It is about 12" longer than I need but cutting it down is no problem. Actually the shorter one they could get but was ~ $25 more:confused2:

I just really wanted to say that so far, they seem great to do business with:thumbsup:
