The 300U is notorious for PTO problems caused by worn and sloppy linkage. I had problems for too long before I took the time to take all the slop out of the linkage and then adjust it correctly.
I reposted this recently but it may help.

Most IPTO are similar on older Farmalls and IH. Here are some important things I learned about adjusting them.
When you have the linkage apart take the time to tighten up any slop using washers and tightening any loose nuts. This is major important.
1.Disconnect the bottom adjustable link near the IPTO housing (a cotter pin and a pin).
2.Remove the peanut shaped cover over the two adjusting screws (if it is there).
3.Then tighten the two band adjusting screws until you feel resistance then another ˝ turn. This seems to “center up” the band linkage. (the front screw is the operating band and the rear is the anti creep band).
4.Now the book says to have someone hold the control lever in the center position (between engaged and stop) while you readjust the adjustable link and reattach it. There is supposed to be a punch mark to line up for center, but I couldn’t find it so I just put it in the center between the on and off notches.
5.Put a small screwdriver or bolt through the PTO shaft hole and loosen both adjusting screws until the shaft moves freely. Alternate adjusting until you get both screws adjusted properly so that the shaft moves freely ONLY with the control lever in the center position.
6.Move the control lever to on and off positions (make sure the lever clicks in each stop) you should not be able to move the shaft with the control lever in the engaged or stop position but it should turn freely in the center position.
Note: I didn’t have anyone to hold the lever in center position (4) so I readjusted and connected the adjustable link with the lever in the off position then move the lever to the center position while adjusting the band screws. It seemed to work that way.

Today's Featured Article - Memories of a Farmall C - by Monty Bradley. When I was a child, my grandparents lived on a farm owned by a Mr. Walters. The crops raised were cotton and soybeans, with about forty head of mixed breed cattle. Mr. Walters owned two tractors then. A Farmall 300 on gasoline and a Farmall C, that had once belonged to his father-in-law, and had been converted from gasoline to LP Gas. Many times, as a small boy, I would cross the fence behind the house my grandparents lived in and walk down the turn row to where granddaddy would be cultivati
