I just purchased a new Snow Blower Model 512 with electric lift. Will I be able, after I clearing my asphalt driveway in front of the house just lift the snow blower an 1" and continue clearing my gravel driveway that goes out to my detached garage. The snow blower skids will not be touching the gravel they will be 1" above the gravel, or will I have to fabricate bolt on skid plates that fasten to the skid plates already on the snow blower to raise the snow blower the additional 1" and slide on the gravel? My older snow blower had the locking handle manual lift that I was able to lift above the driveway surface and continue blowing snow.
