One thing to do, if you haven't already, is to widen your rear tires. No parts needed, just a floor jack, a couple of jack stands, and ideally a buddy.
You'll notice in your owners manual that you need weight on the three point hitch for loader work. I'm guessing here, but somewhere around 800-1000 lbs should be what you want for your 3301. This will help keep the rear tires on the ground and keep you safer. Widening the rear tire spacing coupled with this ballast will help keep your tractor upright, which is of the utmost importance.
I have to keep mine at a set width for vegetable production, about 53" from center to center of the tread on my 13.6-28s. However, during the winter, I can widen them up. I just did that this week and went from 53" to 64". The stability increase is incredible. Unless you need them close in for some reason, move them all the way out. You probably have to swap them side to side to do it, but it'd worth it. Just be careful, they're heavy!
