Well, Ralph, time to get something going on this thread. Been too long since we had a response.
The 400, 700 and 730 western style tractors are some of the easiest tractors to mount and dismount. A friend had a 400 standard that was probably one of the best tractors ever for square baling. They had one of the smoothest PTO clutches and running in oil, very seldom ever wore out. My 700 is great that way also, just harder to get on and off. The row crop is better because you can dismount to the front of the fenders away from the PTO. The lower 4 gears make it easy to match the field and crop conditions.
I have a 900 standard that I need to get in the shop and find the miss in #1 cylinder, then I can use it to plow with the 4 bottom 16 inch plow. No power steering though, but not bad in my long fields. Soon as the beans are off, the 700 will be on the plow.
