Sold my BX 25 "starter" tractor and upgraded to new L6060 with cat 1 3 pt drawbar hitch supplied by dealer. Tnought I was getting a cat 2 drawbar atrachment. The cat 1 has eleven 3/4 inch holes. I want to attach both 2 inch and 2 5/16 balls for moving wood chipper, splitter, empty flatbed trailer ( approx 3000 lbs with no load ). Tractor rear wheels are loaded. 2 inch ball is available with 3/4 shaft but smallest 2 5/16 ball comes in 1 inch shaft and up. So, can I drill one of the holes up to 1 inch or will I weaken the drawbar significantly? Are there other options, perhaps a way to attach a 2 inch hitch receiver to this drawbar? I have front pallet forks that I could possibly weld a receiver hitch to. Appreciate all thoughts, comments. Thank you.
