I had a Kubota B7100, which is a little larger than a SCUT. The Branson I have now is so much more capable there's no comparison. It pulls more, lifts more and carries more. A lot more.
Most tractors have their rated HP in the 2500-3000 rpm range. The rated rpm is usually the same or close to the PTO rpm, the rpm where the PTO is turning 540 rpm. HP being a function of torque and RPM, tractors that have the same HP at the same RPM make the same torque. When the rated HP is at different rpms, the gearing for the drive and PTO generally are changed to match that rpm, so the torque to the PTO and the wheels is still about the same.
An engine that's larger and making the same power might last longer. But as residential/hobby users we're not putting enough hours on our tractors to wear out even the most high strung tractor engine (if properly cared for) in our lifetimes.
