I'm looking to trade up from my BX 24 to something that will be a little stronger/quicker for snow removal, rotary cutting the 3 acre meadow three times per year and various backhoe projects. I would still like to use the new tractor to cut the 1 1/2 acre of grass around my house and plan to use a rear finish-cut mower (60-72 inches). I'm looking at models B7800,B3030, L3130 and L3400. Not sure if the weight of the larger tractors (3000lbs) will trash my lawn or septic system. Maybe there are other Kubotas I should be looking at. Barn size won't allow me to go much wider than the models I mentioned and I only have 7 acres with a long dirveway. Would like to hear any educated thoughts out there to guide me and help whittle down my shopping list. Thanks
