Not sure which tractor to get. Currently have a Kubota B6200 16 hp and just replaced our Woods RM59 finish mower with a Bush Hog RDTH60 rear discharge mower. The problem with the new mowing deck is that it weighs much more than the Woods and when mowing on a slope it takes my whole backend with it not to mention my front end keeps coming off of the ground when I lift the mower, even though we do have weights on the front end. This tractor has always seemed a little under powered especially when going up hills. We mow about 6 - 10 acres with lots of slopes and bushhog about 5-8. The dealer says the b7500 weights more than my B6200 and the power would be alot better than what I have now. I like the size of the B7500 but would I be better off with the extra HP and weight that the B7800 has?
