Jim, Thanks for the help with adjusting my Independent PTO on my IH300U. After I took the time to do it right I went back by the creek bridge to mow some 3-4 ft. grass I had left for the fawns to hide in. I purposely used 3rd gear because I new it would make the IPTO slip and stop. But it didn’t slip a bit. It darn near killed the tractor engine but the PTO did not slip (for the first time ever). I put it in 1st gear and walked right through that tall grass the way it was supposed to. During adjustment I also tightened up the loose spots in the linkage and changed the adjustable linkage clevis which I had never done. I think the linkage being out of adjustment was the reason I could never get it to work right. Thanks again.

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 ½ 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.

I hope this helps anyone that doesnt have a manual.

Thanks Jim Nicholson and delbert Your explanation makes sense I have a manual on this in a box someplace but the info you supplied should get me through. I think the bands are ok I just need to get them adjusted right.Thanks again for the info. Ed

Some times a tidy explanation, and experience are the key. You are welcome. JimN

To clarify one point on the note(4) section.
If you start the process with the lever in the off (forward/down)position make sure to leave it there during linkage removal, tightening screws and reattaching linkage. THEN do the loosen screws, center handle and screw adjustment procedures.
