Just purchased a 2003 Cub M60 Tank. It has the 25 hp Kawasaki and has 524 hours on the meter and picked it up for $4475. Excellent exterior condition with barely a scratch or dent and it drove and performed well in my test run. Deck seemed tight as I could stand on either end with very little sway. Hydro system did not whine nor was there any jerky motion either using both sticks or individually forward or reverse. Ready to mow as the dealer has serviced all fluids and filters, greased, and put new blades on. Couple questions, especially for those that have tanks: 1) Anything I should look for in this machine with 524 hours?? 2) Are belts an issue on this model, read a few negatives?? 3) What kind of life generally on the hydro pumps and system?? 4) How many hours are you commercial mowers putting on this model and with what success?? Thanks for any input, should get delivery tomorrow and need it badly, lots or rain and grass GROWING!! Initially steered away from this used Tank because of my negative feeling towards MTD. But after doing some reading on different forums it appears to be a "cut", no pun intended, above the standard MTD's. Just looking for some feedback on my purchase and hope I'm not disappointed with it! Just generally wondering how these machines are holding up especially with the commercial mowers. Brian S.
