I would like to get some hi hour bragging as an amusing comparison of brands, maintenance, mowing style, etc. ORIGINAL ENGINE AND HYDROS only please. I have a Walker with GHS, but almost always use a side discharge 52, with 2600 plus hours, that is running like new! Year 1995, and I have the original front tires, and one original back tire still on it. Oh, and it is a Kohler 20 command. I know lots of you have many more hours, and I guess I am looking for a possible confirmation that I can still get many more years out of this machine.
