Im sure the weights are available for the 3030, i would guess the front plate would hold 4, 50 pound weights. Last time i priced them they were running around $1. per pound, steele is gone up in price since then? I have a small rotary cutter, landpride 1542, its a small swath but i can use it without the fel and she cuts like a mad dog when i put 25 pto hp through her!
