I bought a Kubota 2100 (21hp) in 2001. I used it for mowing the lawn, plowing snow with the bucket loader and a 5' blade, brush hogging with a 4' mower, and food plots with a 4' tiller. It did ok, but I always wished I had more power.
In 2003 I traded it for a B2710 (27hp). It worked much easier, although mowing the lawn was harder as I had a rear mount mower instead of a belly mount mower. If you can swing it, I would go bigger.
