3320 3 point hitch

[beenthere]

Here is schematic from JD parts that shows the rod (key #28) that likely just needs minor adjustment to lengthen it a short amount. That will tell the rockshaft valve to shift into neutral and stop trying to lift the 3ph arms. Rod on left side facing forward on tractor.

I agree with beenthere. I'm not familiar with the 3320 layout but my 4400 was doing as well. With mine there was piece linkage you could follow up from the lift arms in back that had a threaded rod with a couple jam nuts on it. The had gotten loose over the years and was causing the porpoising effect. Essentially it would lift to position then drift down then go right back up again. Just had to tighten it a little bit and the effect went away.

Once I adjusted this same rod on my 4410 the drop and rise again every 5 minutes or so went away. I don't remember which way I adjusted the rod but it's very simple to do. On my 4410 the rod is on the left side fastened to the rockshaft arm.

Thanks. I'll check that out today. Another question, I have a 425 garden tractor that I am wanting to put the 54 inch front blade on. I found a guy who has one complete with the hitch. He had it on his 2210. I don't think it will hook up to my 425. Any thoughts?

Think you will need the correct quick hitch for your 425, but the 54" blade may then fit.

Proof test it before you buy it, would be my suggestion.

I'd appreciate a photo of this.

My sister has a 1025R with front blade. I went over and checked it out. The quick hitch pins are in a different location. Plus the support bar hits the 425 frame. I'll keep looking. Thanks everyone for your replies.
