Add this one to the stupid moves list. I changed my mower blades last night. Before I started cutting this morning, I was going to lift up the deck and take a peek, as usual, but then remembered that I just changed the blades and cleaned the deck last night, so I skipped it. Well, as I engage the clutch, the engine bogs down and almost stalls. Of course, I tried it again, thinking that I just dumped the clutch too soon. Same thing. Well, guess what I found on the spindle, my one inch combination wrench! I'm just glad I didn't break anything.
