Here are the 2 decks side by side.
The front baffle on the Northern is very similar to the one I tried except for where Ive marked the "1". The one I had curved back sending clippings further backwards and closed the chute more than in this pic.
Its doesnt show bolts for bolting on either so not sure whats going on with that. The one I tried wasnt adjustable but it did bolt onto where the baffles on the southern deck attach.
