In my opinion,there are two factors ( besides the intended use i.e. moderate mowing versus cutting brush versus cutting 1 inch diameter saplings, etc.) to consider. The PTO horsepower of the tractor(s)using the cutter and the weight of the cutter relative to the weight of the tractor(s)using it.
Most people focus on the former, but the weight of the cutter relative to the weight of the tractor needs serious consideration because it affects how the tractor/cutter combination steers, brakes, it's stability on hillsides, and the ability of the three point hitch to lift the cutter(it it is mounted on the three point).
For example, an 8N or a TO-30 has adequate horsepower to utilize a 6 foot cutter in moderate grass conditions but the three point hitch is limited to about 750-800 lbs in lifting capability. (There are heavy duty 5 foot cutters that weigh near to 1000 lbs.) At weights above approximately 500 pounds, the front end needs ballast to allow for steering capability and there is some concern over climbing hills with the mower either raised or on the trail wheel.

I have a Ford 4610 and a TO-30 and use a 6 foot rotary cutter that weighs in at about 750-800 pounds. I don't even know it's on the 4610 when I'm using it relative to power requitements and steering, braking and stability. I have only moved it around on the TO-30 and while my 3 pt handles it very well, another few pounds of weight on the three point and the front wheels will be off the ground. I have done some calculations and I think I need about 100 pounds of ballast at the front end to use it safely. I'll either put a weight bracket on the front axle or ballast the front tires.

Hope this gives you some food for thought. Be safe out there.
