Well while mowing yesterday the 2 yr old Troybuilt rider started acting up and then decided it didn't want to move. Motor runs good but won't move. It completely quit when I got it into the shed. Then the 18 yr old Yard Machine that hubby was using blew the motor. Down to no mower again. Really aggravated the Troybuilt mower quit. Not impressed. Will be taking it to shop and hoping not transmission. Probably not get other fixed. New motors start at $500. SO my question is what brand of mower has held up the best for you? Will be tackling this after get back from vacation.
