A three (3) range HST provides a lower LOW and a higher HIGH, relative to a two (2) range HST.
Your concern should be two (2) range HST tractor running out of power moving uphill with FEL and Backhoe attached. Do not load the rear tires with liquid, which would exacerbate the problem.
For some, lower overground speed of two range HST in "HIGH" can be tedious, but not a concern over three acres.
You do not have ground contact applications in your plans. If you wanted to plow, subsoil/rip box blade, etc., the lower LOW of a three (3) range HST allows you to tackle tougher dirt and penetrate soil deeper without stalling out. Tractor weight helps too, but less directly.
Nah. SCUTS have teensy front wheels. You would high-center on every downed branch >6", holes, burrows and ruts. A small compact tractor with larger wheels/tires is much better for your conditions.
I don't think it adds lower, low speed or higher high speeds, rather it splits the total speed 3 ways and gives you a medium gear that tends to handle most tasks.
I think with a 2 gear range transmission you may find yourself having stop to shift into high if you are wanting to move to the other side of your place.
That said I find 4 MPH is fast enough to get me around on our 14 acres, but our place is hilly and is divided into 2 and 4 acre pasture and one of the 4 acre pastures has lots of trees to weave in and out of.
I think you would need to determine if stopping and shifting or just running in the mid range is better for you.
