Bird, I went to the farm store tonight to look at the same over run clutch that I have on my tractor. I discovered that the clutch should slip when I rotate it clockwise when looking at it. Apparently mine has froze up a little, which might explain why it would sometimes push me when the mower is on and I try to stop. So, I got my son to set on the tractor with it in gear and his foot on the break, while I attached a big pipe wrench to the over run clutch. Now armed with the knowledge of which way it should turn, I put all my weight into it. Low and behold it moved (after turning the engine over a little). It is free and I was able to line up the hole with the roll pin. All down hill from here. Thanks for the reply. /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif
