I have a Hardee with two tailwheels. I didn't shop brands, but this one looked okay at a dealer I liked. I fabbed a door on the back of the deck that I can open to sharpen the blades. With the twin tailwheels, and sharp blades, it will cut almost equal to a finish mower. I wanted one that was a little wider than the rear wheels, for trimming the fenceline, and trails. The twin rear wheels cut down a Lot on scalping.
It's their medium duty cutter, but has the heavy duty gearbox. It's over 20 years old, and has been great.
I keep a 40 gallon tank welded on it, with two pumps. One pump is for the "boomless" boom on the back, that can cover a 30' swath, and the other pump is a higher pressure, but lower flow, for a wand that I keep up by the seat. I have to open a ball valve to use the boom, but the wand can be used with a flip of a switch on the dash for spot spraying.
This stays on the 70 hp tractor during grass season.
