i think i was mistaken. i believe that is not a radiator but an oil cooler grill. so i don't think this machine takes coolant, rather it is air cooled.
yep. I have a 720 that saves me lots of back and other pain. Good luck with yours. I'm still thinking about how to add hydraulic lines for attachments like augers and backhoe, but don't have either of those yet and haven't spent much time on it.
