Finally did it !!!!!!!!! Been dreading it for months.

Good job and timely.I had a friend rip the pto case out of his NH using a post hole digger that the shaft was too short.
Gets expensive fast.His tractor was brand new and the dealer sold him the PHD.

Did it come apart and flail the living daylights out of everything on the backend of the tractor?

It snapped the gear driving the PTO,dealer did not warranty....

Now Im wondering about my drag type Rhino TR120. It hooks up straight just fine, but Im wondering if I am bottoming out when I turn. Im trying to think in my head if this would shorten or lengthen the distance between the pto shaft and the implement gear box??

I did a quick CAD layout.

In a turn, the implement pivots about the drawbar and the PTO shaft pivots about its front u-joint. If the drawbar pivot is closer to the implement than the u-joint pivot, then the PTO shaft shortens in a turn.

Good catch.

Suffered a confidence shattering setback. LOL was shredding some pretth heavy stuff this evening and heard an abnormal sound. Looked back just in time to see the PTO shaft come loose from the gearbox. Immediately shut things down and got off for closer inspection. Female portion just distal to the slip clutch came off the gear box input shaft. Looks like a bolt or pin should go through both the male and female shafts once joined. I wonder now if my running it some last year with the shafts bottoming out sheared this pin and the vibration of normal use allowed this??

That's more than likely what happened. I can't tell from the pictures(blurry), can it be repaired?

 

[pharmvet]

Yes, I think so. I don't think there was any damage done. There is a hole through the gear box input shaft (perpendicular to the axis of the shaft) as well as a hole through the male portion of the clip clutch attachment point. I suspect there should be a pin or bolt through this hole to prevent this from happening again???

Yes, there should be a bolt thru there. But while you have the opportunity, pull that black plastic cover off and inspect the shaft seal, and the front of the gearbox for cracks. While you are at it, check the tractor end also. Look for hairline cracks in the paint. If unsure, use a magnifying glass or something.

In your second pic, of the shaft. See the 'cutout' section that is about 1/2 inch from the end? The bolt that goes thru your slipclutch. slides thru the slot(cutout section) on the black shaft(that holds them together).

Ok, I can see how that works now. Wonder how that slid off??
