When I bought mine I felt it tippy as well so searched and found a place that custom makes wheel spacers for anything. I searched google and 3046 tractor. He can make spacers up to 6" wide for the 3046. I didn't want to be obscene so I went with 1.5" each front wheel and 3" each back. WORLD OF DIFFERENCE! Just note however, rumor has it this will void axle warrents as JD quit offering spacers 4-5 yrs ago. I could try to find where I got mine if interested. Been 5 yrs ago. His manufacturing tolerances were fairly tight after I had them powder coated.
