Yes how old is the JD in question? My Scott's PTO would disengauge while cutting. I thought there would be an adjustment to correct this, I was wrong. When I pulled the deck off I found the tennisioning pulley bracket to be almost rusted away from the deck. Got some sheet metal, pulled the wielder out and went to work. Add some paint, new blades,and belts- never cut better. My Scott's sat outside for 10 years all summer long... but not the new Cub Cadet !!
