Paul, both the Fergusons and the Ford "N" series do not have live ptos. What that means is when you hit the clutch to change gears, the pto stops. Contrary to popular belief, it is really not much of a problem. All you have to do is install an over running clutch on your pto shaft. It just slips over your pto shaft, and you tighten it with one screw. Takes about 15 seconds to install. It allows the pto to spin in neutral while you have the clutch pressed in, and allows the implement to keep working while you have the clutch in. It also lets the implement keep spinning in neutral when you turn the engine off, so something with a lot of momentum like a rotary cutter won't keep your engine moving. The over running clutch costs about $25, and if you put it on, not having a live pto will not cause you any problems. That allows you to get a good working tractor very inexpensively, because the Fergusons are great tractors, and sure are cheap compared to new ones.
