This won't help anybody but may make you chuckle and have a quick look before you start that engine! The local Gleaner agent parked an N7 out in his yard for a week or so. One of our possums, about the size of a very large domestic cat, found a very comfortable home in the radiator housing, between the fan and the radiator core. The inevitable happened! The combine was started and the possum took out the radiator, the fan and other assorted bits plus a few thousand bits of mashed up and stinking possum to be cleaned out of everything. Cheers.
