I had to pull my super out of retirement the other day. I haven't really used it for a couple of years now. I have been mowing with a zero turn and kinda got spoiled. Anyway my zeroturn has engine problems now. Anyway back to the 2072, I charged the battery and I'm back to mowing grass but the deck bearings are like screaming. I have greased them but it's not helping i guess they went dry from sitting. Any tips on replacing them or better bearings?
