To me, having owned various twins and large singles over the years, I like either, but I like the fuel efficiency of a OHV single better.
Kohler Courage V-twins are similar to the Command series, but use jamb nut valve lash adjustment as opposed to hydraulic lash adjusters on the Command. Commands have nicer features like oil coolers, supposedly bigger bearings, etc.
IMO, that's the key to the lower cost riders; Make the machine last as long as the engine. With reasonable care, the engines typically outlast the machine, cutting deck, trans, etc..
Letting that deck 'hang' when mowing, scraping it, blowing the machine off with your leaf blower and storing it in dry storage makes everything last many years.
Thanks for the insight. Yes, I tend to take pretty good care of my yard equipment and I'm only mowing a lawn so the lower end stuff should be fine.
An early copy of the sears black friday ad is online now and shows this mower for $989.

Yes, I know its a lower end unit. Its similar feature for feature to the JD D105, and pretty much the same unit as the one I posted earlier except the Kohler Vtwin is swapped out for a Briggs 17.5 (which is similar or same as the engine in the deere). Same CVT trans, although I think with the craftsman you downgrade from a cast iron front axle to a steel one.
I went to both HD and Lowes and asked if they would honor the 10% off coupon on riding mowers - yes, except for the JD. So that makes the price split between the two $500, or 50% of the cost. I like the Deere and I do have a dealer somewhat closeby for support, but I cannot swing a 50% cost difference for JD.
