There’s a story about how my tractor got in this condition, at the time when you’re reading this , our hero who never gives up, is being told by the evil voice on the other side of the phone that you cannot get an exhaust seat alone for your D D- 902 engine . The voice says that he will have to buy the entire head of the engine at a substantial cost. How will this story end ?

Well your going to be sadly disappointed, Kubota doesn't use intake or exhaust seats in their heads. ;)

A good engine machine shop can install valve seats and valve guides in heads that originally used parent metal for these features.
Very common procedure in the days of leaded fuel as few engines came from Detroit with actual valve seats. Continued on during the conversion of older engines to unleaded fuels. Also, very common repair in diesel ag engines due to long life of bottom end.
