Listening to folks talk about the total wisdom and necessity of owning a 4WD unit makes me remember the Farmall A I've had for over 20 years now. It has 17HP, is crank start, is now 71 years old!, and it has only 2WD and I've never had a problem with it EVER!. A tractor owner/driver has to gain experience in driving tractors as I did back on the farm and one learns to compensate for darn near everything. That old A served me very well and while small Japanese tractors have various weight shortages, careful weighting and really knowing how to drive 'em goes a long, long way to getting effective performance from them. If you just came from the bowels of Detroit, yes, you need 4WD. If you grew up and started drivin' when you were 5, you really learned how to handle iron and you don't forget and very often you don't need tractors that have to be tricked up to get 'em to perform. Americans of the latest vintage went to American schools where nobody is left behind no matter what. They need a heavy Cat tractor with 4" growsers to get by on flat ground.
