The design and construction of the Contoura is far advanced over anything else on the market. It doesn’t have a belt drive, which always seems to be the weakest part of a mower. Instead, it’s gear-driven and therefore handles even heavy grass with ease. The Major Contoura leaves a perfectly striped and even finish - far better than we were used to. I get a lot of pride in walking out and looking at the finish after it has been through the rough.
