Yep, i got one of those angle finders to day and took it with me. The steepest hill i was on was 27 deg. And that was about all i can do. The mower may do just a hair more but not much, and me, i was to scared to go any further. You are one brave man to go an a hill thats 35 deg. Oh, you guys need to get one of these things, those hills will fool you, they are not as steep as they look. btw, for all you Dixie hatters it was a Dixie chopper with the 50'' deck. so smoke that.!!!! Hope you see this Envy Lawn. Later.
