I have just purchased a 98 XW2500 with a 25 kohler and 60" deck for $500. It has been sitting for a few years, and I know it is going to take some time and $$$ to get it back in shape. I know nothing about these mowers, and I will take any advice given. I checked the compression and it is a little low so a rebuild is probably in the near future. I am unsure about the fluids to run and how to drain and flush the old oils. The deck is solid and straight, and the wheel motors were rebuilt not long before it was parked. I think I can bring it back to life and have a good mower at a good price. Any thoughts or advice?
