    I am a 35 year road grader operator. I've been running a 140M for just over 4500 hours. I noticed that my rotor cuffs are giving me problems due to the arm rests being mounted directly to the floor while the seat is an air ride. It is more noticeable at high speeds and on rough roads. I didn't have this problem with the 140G and earlier blades with steering wheels. Has anyone else noticed rotor cuff stress?
