I have used a Ferguson to20 for 30 years to mow pasture. I had 1 1/8 6 spline pto shaft on it with override clutch 1 1/8female- 1 3/8male conversion. I replaced the shaft and bearing this past summer in a kit, all was well. I still needed override clutch so I purchased one 1 3/8 female- 1 3/8 male and noticed the spring pin hole was 1/16-1/8" off center from the coupler. When inserted the spring pin put tension on the butt end of the coupler against the pto shaft hardware. The problem I encountered was that the coupler wouldn't over-ride when the clutch on the tractor was pushed down and the brakes applied while the rotary mower was spinning. I took the spring pin out and when the tension was off the override coupler I could manually turn the coupler and make it override. Any ideas or adjustments that would help this work?
