Kubota L4701
Hey all. Fired up the tractor this morning and while greasing the loader while letting it warm up I noticed a few puddles of anti-freeze beneath the tractor. Looks to be leaking from a few places:

The radiator hose is an obvious one. Looks like maybe the hose shifted where it clamps on the engine side. It's leaking from both ends though:

I'm not sure why it's leaking so much over on the right side of the engine though, by the oil filler cap:

I pulled back the plastic sheathing/cover on teh hose on top where it looks like it's coming out, but there's not a buildup of coolant in there. However, that hose does look to have an abrasion at least, if not a cut/tear in it.

Best guess I can come up with is the coolant froze in the line and when I started it up/it was pumping, it built up pressure and caused the leaks. Does that sound feasible? Any other ideas?

I can un-clamp and re-clamp the main radiator hose. Anything else I'd need to do to get things back up and running? Any concerns?

Hrm, looking at the workshop manual that's a fuel line that is abraided. Guess I'll prioritize replacing that...

Well, for anyone else who may run into this issue - got it back from the dealer on Friday. They said the thermostat was faulty and replaced it. Had them a coolant flush and replaced the radiator hoses as well.

Haven't fired it back up yet but hopefully we're back in fighting shape.
