We just dug a trench for electricity. Would have to agree that it would take a heck of a trench to dig a big loop outside the house for air transfer. It would be a monumental undertaking. Big expensive conduit.
I am sure that even if were sealed it would house all sorts of nasties after a few years. Bugs, rodents, mold and other filth that would be recycled. and impossible to clean out. Even a small leak allowing moisture in would likely bring in water which would compound the problem.
I like the original idea of pumping cool water through a radiator. It would still eventually clog up.
Nice tractor and Yamaha btw.
