OK, weighed it today full of grass clippings. The grass was 6 inches deep when I cut it so it definatly was not dead. The answer is 63 lbs. Much less than we thought. I even stopped once, lifted it off and tipped it all the way up on its end, and then re-attached it and mowed until it was full. Not sure how you got 103 lbs. If the grass was wet, I guess it could possible reach that number?
