I debated the same thing last fall after installing an outside furnace. Decided to go with the 3 point hitch model. Bought a 16 ton Ramsplitter for half of what the other type would have cost. Been very pleased with the 3 point hitch model. Haven't found anything that was too tough for it. I usually run my tractor at about 1200 rpm.
WOULD RUN A 200$ MOTOR or a 10000$ tractor
