A solution might be to build a rear weight. The 3 point is often rated at 1000 lbs, so a 400 or so lb weight would be good.
I'll let you do the math, but the method is simple.
Large plastic garbage can, get ready rod, re-bar or whatever cut to length & ends ground smooth for the lift arms, pass rod through garbage can at correct angle. Another piece bent & joined to connect to the top link. Check for proper fit & operation, fill with appropriate amount of cement gravel & water. Ready mix is nice and convenient if you don't mind the extra cost. Once the cement has cured the garbage can may be discarded.
Weighted tires is also not a real option for me. I should have had this box built for the landscaping I did this week, but there has been too much else happening here.
