This is what our dealer "Pacific Lawnmower Works" and us have come up with to improve the mulching plates for the 72" Scag mowing decks. Inside view shows that the bottom of the plate has been trimmed to remove lip. At the front it is trimmed at the point where it start to angle back and at the point where it matches up with the deck on the rear. This removes about 3/4" in the front and about 1/4" in the rear. Bottom view shows the reinforcing plate. Side front view show the three mounting tabs. The two tabs on top mount to the outside of the deck, while the front tab mounts inside. Material used is 3/16" plate steel and 3/16" X 1 1/2" angle iron. We are bolting these on for now and if they work out will be welded into place.
