Due to lots of rain all week and more forecast for tomorrow and today was the only dry day, I set a new record today for lawns mowed. All the same neighborhood, lots are typically 100x200 standard residential although a lot of them have smaller wooded back yards. 39 yards done, with a walkbehind, and no sulky. Exmark 48" TTHP which I had put in a 19HP engine to start the year really helped. Mulched too, no side discharge for me. I did have a guy on the trimmer/blower. 12 1/2 hours. Who can top that?
