After adjusting the pto on my 830 today I feel like I can assemble a ship inside a bottle. Doing all of the adjustments through a 2" access hole while contorting my body around the frame of the hitch was a real treat. Although it would have been even worse if it had been the early style with out the external adjustment indicator. There is no more adjustment left on the clutches. In the service manual it shows that you can just remove the pto clutch housing and not the entire powertrol assembly if you just need to work on the clutch disks. Has anyone ever done this repair before and is it a big/complicated job? Thanks, Bill M.
