I have about 7-10 acres gently rolling pasture to bushhog (maximum 3% grade). About 2-3 acres will have numerous trees randomly set out about 30 feet apart. I am considering a B series Kubota (30hp), however, I have been told the largest bushog I could run would be 4 ft with the B series. A dealer says I need at least a L2800 to run a 5 ft bushog. I like the lighter weight of the B series (about 1700 lb) vs the 2600 lb for the L2800. I will also do some tilling (4 ft tiller is fine). Regardless of choice, I will be spending at least 12,500 for the tractor. Thanks in advance.
