Timber - The 108 is just a 110 with smaller engine options. The 110 is now on Joel's site. Prices are roughly $400 less than the 853/749.
JS - I agree. I imagine the added cost of a second clutch would price it out of the market.
I know what an independent pto is, but what's their advantage on a two wheel tractor?
For me I would rather have a hydrostatic 2 wheel tractor instead of a independent pto. But those new Rapid Gravelys were too expensive.
