Has anyone seen these things for commerical properties???? What do youse guys think of them. They are made by SGS, Self-Guided-Systems. It is gas powered, runs for 12 hours unlike most of us with coffee breaks, lunch, etc. It mows the grass while u go trim, cut trees, sweep sidewalks, what ever else needs to be done. Mows one whole acre per hour. It is a hybrid so needs less gas. Has a 38" deck. Sensors all over, car alarm, everything u know. Now i want to here what youse guys think. In my opinion it takes the fun out of mowing your lawn.
