Check the coolant level on my new x720 and it is a little low. I didn't see any signs of leaks nor is the tractor overheating. Got the part number for the jd cool-gard pre-mix TY26575 but it will not show up on the jdparts website. So far, I have had great luck with my local dealership and would like to buy it from them. Could just go it and get it but it is much faster to order it on line.
