What is the rated 3 pt lift capacity of the two tractors?
I have a Kubota B2710 (27
hp) and I can't imagine a 6' bush hog on it, nor mowing 30 acres of pasture with it. I use a 50
hp tractor for that although it's loafing along most of the time.
A hydrostatic transmission is certainly nice for
FEL operations, but it robs the net power going to the
PTO. Again, 30
hp sounds low for a 6' bush hog.
