If we are on to tractors:
Dad's favourites from farming days:
Massey Ferguson 65
Massey Ferguson 35 - the later 3 cylinder Perkins Diesel- the first powered vehicle I ever drove.
Most hated tractor
Massey Ferguson 35 - with early 4 cylinder diesel. Had to be parked at the top of a hill and needed at least 1/2 a mile to bump start. It could be worked and got hot, be turned off for 20 minutes and then refuse to re-start.
