All kidding aside, even us Kohler owners appreciate your participation here on TBN. I can think of a lot of dealers in general that participate, but none other than you as far as factory support of engines goes. Thanks! Many of your suggestions don't apply just to your products and are quite helpful to all gas engine owners.
As for running one of your engines in my equipment, I haven't had the opportunity to purchase anything with an engine in it lately. One of my main reasons to get the Power Trac was to eliminate several pieces of motorized equipment by using the one, multi-tool platform. So far I have eliminated the usage of two snowblowers, and an old lawn tractor, a late 70's International Harvestor industrial tractor loader and an old, beat up 4wd pickup truck. I've also mothballed my wheel barrow. I'm saving money and time on maintenance costs and saving space in my garages.
I have the PT-422 and the 12kW Robin generator, both with the same engine. The Robin generator has never had any of the runability problems (starving for fuel, dieseling, backfire at shutdown, starting in winter, etc.) that the PT has experienced.
