Personally I think it might be interesting, but it does seem like the Sub-CUTS might have to be listed or defined.
Most people, even the JD folks consider the 2210 a Sub-CUT but do not consider the X5xx series Sub-CUTS, they consider them garden tractors. But the X series and the 2210s are basically the same price and similar in size. As for other brands, the Massey GC series, the NH TZ series, and the Kubota BX series tractors.
If the list could be defined, and perhaps refined over time as new entrants to the Sub-CUT class are introduced, it would be nice to have a level and balanced discussion about these tractors. I noticed someone on the Kubota forum posted a question about the comparison between the Massey and the Kubota and things got close to being ugly.
