It is a band operated PTO. The bands are adjusted as follows: Move the lever exactly half way between the locked on position and locked off position (little flipper catch on lever. Use bungies or ratchet straps to hold it centered. Measure this position. Take off the little dome metal cover from the adjust screws. Loosen the jamb nut, and tighten the front (away from you) screw until it is just a bit tighter than the point at which it begins to feel tighter as it is screwed in (maybe a eighth turn) then back it off until the PTO shaft will turn with least drag (about 3/4 turn out) and tighten the lock nut while holding the adjuster. Do the same for the closer adjuster. If the screws go into the jamb nuts and get flush with the top surface of the nut, the bands are probably worn out, and may be operational for a while, but plan on a rebuild. Now (tractor off) push the the lever down toward the brake footplate. As it goes down, it should get harder to push when it is about 4" (or so) away from fully OFF. and be noticeably harder to push for the last inch, but not real hard. (this is the brake band tightening on the drum in the PTO unit. Then pull it up and do the same feel. The ON position should feel the same way. The shaft should turn pretty free when the lever is half way, and not at all when in either ON, or OFF. (tractor shut off) If it slips now, it needs a rebuild. Jim

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
