Cracked engine sumps
I have two mowers, MTD w/B&S550ex and Husqvarna w/B&S625e, where the engine sump that is bolted to the mower deck is cracked on the upper surface from the outside of the flange near a mounting bolt towards the middle of the sump. They only have 3 or 4 mounting bolts which do not appear to offer enough support when the mower sees heavy use. These mowers are used in foot tall thick weeds with occasional hidden branches or rocks. The tall weeds are unavoidable since I can't keep up with mowing at this location and several areas are only mowed once every year or two. (A landscaping service mows the good lawns and I get the rest.) The one advantage of these mowers is that they are baggers which means a clean "lawn" after one pass. My Gravelys can handle the tall grass with no problem but then I have to rake to clean up.
Rather than replacing the sumps I am planning to clean and JB Weld the cracks and bring the total number of mounting bolts to 12 evenly spaced around the flange.
