Received 30in. Two bin rear bagger (247.240690) for craftsman rear engine rider (247.29000) and began assembly today. All went OK until fitting the bagger tube to the mower deck. If I fit the top bolt first, the tube fits the curvature of the mower discharge but the rear bolt to hole is misaligned about 1 inch. If I mount the rear bolt first and force the tube to the top bolt, there is a space about 4" long and 3/4" wide where the tube and mower deck are misaligned. Also the safety is not depressed to allow the mower to start. I have tried multiple times to assemble with no success.

Hi,
I would say you have a wrong part. Often the fit is tight new, but not off by that amount. The parts breakdown calls fro part #731-09227 for the chute. I would suggest a call to SearsPartsDirect helpline at (800) 252-1698.
Peace,
Clarke
