Matt - no, the mower deck will not mount back to your tractor if the frame for the LBD48D is still installed. Depending on the brand and model of tractor you have, chances are the front mounting brackets for the mower deck are the same mounting brackets that are required to mount the LBD48D, so if the frame for the plow blade is mounted, there is no way to hook the mower deck back to the tractor. You would need to "dis-mount" the LBD48D in order to put your mower deck back on your tractor.
