think you'll really like the xx40 series. re: trailers, you might go to the transportation & trailers discussion on this tractorbynet. for hogging, I'd recommend having rear tires (ag) fluid filled for safety & traction. my guess is that would add around 600# per tire....you can get the tractor weight from the spec sheet on the Kubota site, then have to add the fel weight (don't think they figure that in?) my rough guess is that w/fel & ballast in rears, the rig would weight around 7200-7500. I'd go with a 6' hog (med duty), ask your dealer, the tractor should handle it (check pto hp requirement of hog) that would put the total weight around 8500. definitely go gooseneck, but see what the experts say. BTW the price increments between the 50-60-7040 is (was) around $1500. good to do the homework and look to future needs before signing a 3.5 yr commitment good luck bb
