Never heard the term "dependent" PTO, unless maybe it means the opposite of "independent" PTO. Non-PTO is another new one.
Here's a quickie explanation of terms-
1. Non-Live or Transmission driven PTO is what your Ford 850 has. PTO is driven off the transmission, so when you press in the clutch, both forward motion and the PTO stop. Except, if you are using an implement with inertia in the revolving part (bush-hog), that inertia of the turning blade will push the tractor forward even after you depress the clutch- into the fence, the side of the garage, well, you get the picture. Solution is an overruning clutch on the PTO shaft, as outlined in other posts.
2. Live PTO- Uses a two stage clutch- halfway down stops forward motion of tractor, all the way down stops PTO. So you can stop the tractor, without stopping the PTO. This is very useful in baling or combining, especially- so you can stop or slow the tractor when the machine starts to clog up, but keep the baler running to clear itself.
3. Independent PTO- operates by a separate lever, completely independent of the clutch. This is the best of all- just put PTO in and out of gear whenever you want. This is why the early Olivers and Cockshutts were the best tractors ever. IMHO.
