Almost an acre per hour. My old b7100 with 4' mower would not do that, have to wait and see what the L3010 will do. Should be much easier on the tractor, even if not much faster. Mowed some short stuff, 10 to 14 inches, weeds and grass, while adjusting the mower height and just trying out the tractor in general. In 95 degrees, ran for about an hour, tractor ran very cool, mostly in 3 low, somtimes in 4 low, Kept rpms up easily.
