Hey Guys. I wanted to update you all on a pair of M665's I bought for this season. The initial results look promissing. I am very happy with the quality of cut and power from the 25hp Kohler's. They handle well have good ground speed. Things I have learned- 1.Don't try to stop going down hill. It will NOT! 2.Fill the tanks, cuz they love the gas. 3.They don't turn like a grasshopper. THings I would change- 1.Put gas gauges on them!!!! 2.Different rear tires, OEM are not aggresive enough!! Tends to skid alot. Will let you know if I have any problems, but so far I am happy.
