The cover on the deck like to collect grass and will push off the belt if you don’t clean them out.
I added 4 thumb screws two on each side to make it easy to take the off and clean them out. After the 30 day return period I will cut some holes in them to make easy to blow out the grass.
I have over 6 hours on it so time for the first oil change. I will switch it to Mobil one oil.
