I would also like to know if anyone has any knowledge or has had any past experiences with the integrated machine control, primarily information on the durability of these "stroke sensing hydraulic cylinders". I know this technology is fairly new to the market compared to the aftermarket mast mounted antenna systems, but does anyone know anything about the accuracy of these sensors say 5-10 years down the road after using them every day? Are these hydraulic cylinders something that will need to be replaced and recalibrated regularly? Seems to me they would lose accuracy after a while and have to be replaced or repositioned. Thanks!
