I am trying to identify which of the two baggers I have that's supposed to fit my Craftsman LT 1000 model 917.271024. I have one bagger that is a three bin and the other is a two bin but I may have misplaced some parts. When I try and mount them they are now hitting the back fender of the mower. Can you get me the manual for the 917.249791 so I can verify it is the one for my mower. Thanks
