This was a concern of mine. I have found several skid mounted "coil spring wire" that are able to tolerate reverse motion. I am leaning that way. So much honest info on JD!
I've trained my self to consider the back up alarm as a scratcher warning.
Coat hanger style provide the best down pressure. SPI carries the behind the wheel mounts.
Using the hose, as a rail guard, was a fail.
The rail guard needs to go on the rail.
When everyone else is trying to grab snow, kick snow into the skid, etc, I just ride. No sticking slides. No over heating.
Remember, the back up alarm is now the scratcher alarm.
