The diesel now has 35 hours on her zero trouble to date. This is a 128 unit or house complex. We just took over the lawn maintenace so the spring growth was thick. The deck height was set between 1 1/2" to 2" depending on objects in the ground or the topographics of the complex. The pics are one pass, the clove was so thick it did require some double cutting in some places Again I cannot stress to those wondering why so much power??? that you can never have enough power, the Cat diesel did lug down in the thickest of clove, I was mulching it, or I would slightly open the ACS. also I have no mulch kit. when I would open the ACS chute the diesel had enough torque to hit the sideing with grass clippings. I am using the Gator Fusions they seem to work the best vs the Gator mulchers, so I might hold off on the X blade set-up for now, I was working on. The diesel is still sipping fuel even when lugging. I filled it up today and my calculation are still at .66gal/hr. I can almost bet that even in the thickest of grass the fuel economy will not change much. The Cat diesel runs cool about 195 until you get in the very thick grass then it will go up to 200, and stay there all day. Over the last ten years of running ZTR's this AOS diesel is buy far the best diesel or ZTR for that matter on the market. The productivity, and cost savings BB has is simply amazing.
