I can't decide on which walk behind to get - I will be buying my first mower soon i have 4-6 lawns so far including my own and am leaning towards buying a gear drive. I have a lawn with a slightly steep hill in the front yard, will a gear(belt) drive be ok on this or will i have a lot of problems . I want to spend around $3000.00 . I just dont want to wish i bought something else. I also don't know which to get 36 or 48" fixed or float. I was planning on the 36" but now i'm thinking 48". -Do the 48 " fixed scalp and bottom out a lot. is 15hp enough and is pistol or ECS better for someone 5'10" 195 lb. to handleon hills around trees. THANK YOU for any input alli do know is that i am buying an EXMARK. You guy's are very helpful ps. is the Viking Hydro any good and how much.
