Have been plowing Way out West for seven winters now. It seems not to matter what Coast one is on, one problem seems to be shared by all of us. How to keep a plow from digging up the turf, cinder, gravel etc. There is some high tech stuff out there. What we need is a sensor linked to the toggle or keypad to "read through the snow to the ground", and adjust the blade heighth accordingly.I'm sure there is existing equipment that could be re-configured to meet our needs. Hope that one of us can come up with an easy, cheap, universial application. Hope I don't have to read through posts of why it can't be done. Wish I had the resources to do it myself.
