I use a newer 26 or 28 horse Kubota, BX series, with a bucket. I just chain around the drawbar and pick'em of the ground, It puls out two pretty big 16 footers and dosen't think twice. I could pull more but it wont fit on the drawbar I also pull out single 40 footers and it works fine for that. I also run ice chains on it and I think that helps alot.
