I have a 620 baler, and a 1650...I can't get the close coupled hitch to work. The PTO doesn't like making turns... The tractor is set for 30" rows, I have the tongue moved over to get the baler pickup beyond the tire, But I don't have nice straight flat fields to bale. So any Ideas on what I don't have set up correctly? My only idea is to lengthen the tongue and PTO to lessen the angle on the u joints in the PTO....
If you have the tractor narrowed up for 30” rows you should be already helping the problem. Check your PTO U joints for rust and lack of grease, that will cause problems. I checked the internet for Oliver 620 baler and the tongues did not look all the same. The 720 had a longer tongue, and that will help the operating angles of the U joints in the PTO shaft.
Not that much, because you adjust the baler chute different. You adjust it so the strings are right in the wagon, so by having less resistance in the chute it comes out about the same.
