Possibly a simple adjustment.

Minibull, welcome to GTTalk.

 

I would try two things first:

1)  Locate the PTO engagement 'knob' at the front of the transmission casting, probably under the battery, and ensure that the bolts holding the pivoting engagement lever are snug.  Loose bolts there can cause issues.

2)  The lever leading from your dash to the engagement lever there at the front of the tractor casting should rub on a crossmember along its path.  If it doesn't, do what it takes to put a bit of bend in it so it scrapes.

 

 

Those are the simple things.  Beyond that, you might need to remove the PTO 'knob' to see if your locating ball and spring are still intact, and it is possible you have a minor issue inside the transmission with the "dog gear sliding block" having escaped from captivity!  But check the simple things first, then let's move on from there.

:welcometogttalk: As Howard said, check the 2 bolts retaining the shipper shaft, and the linkage for the shifter for the "simple stuff"  If all that checks out there is pin on the end of the shipper shaft that wears and then doesn't put the dog gear "over center" and causes issue.
