Lol, well, as fun as that would be, I don't think their would be a comparison as TSO has 10 or so more HP. I also think we should develop a "field day" to test various components of tractors.
Such as:
1) get a large dumpster dropped off to see who could reach to dump in there.
2) attach a rotary mower and see how the machines handle them (maybe even various duty rotary mowers). Also a finish mower with variable widths.
3) same goes for pulling different plows
4) compare tire traction in various grounds and various conditions. (Snow on grass or asphalt, loose sand, mud etc.)
5) lifting pallets from the 3pt.
Obviously the list could go on forever and I am sure there are these answers all over the net, but this would be just true fun and real world applications.
