Can SnowBear Winter Wolf Snowplow part # SB324-167 be Used on Gravel  

As I was reviewing specs for this plow, I noticed one bullet point toward the end of the Features section stating...Sturdy steel edge scrapes over a variety of solid surfaces - not for gravel or sand. I live on an acreage in the country and will be plowing our gravel driveway. Is this plow edge unuseable for crushed rock driveway? I have a 2003 Ford F150 XLT Extracab with a Triton 4.6 V8 engine. I am looking at this SnowBear and comparing to the Detail K2 Storm II Snowplow - 84inch Wide x 22inch Tall as my finalists. I will be plowing my own driveway and will not be doing any commercial plowing. Because of limited garage space I need a plow that allows for easy movement for storage along one 16foot wall where I have 6 feet depth of space to accommodate depth of the plow in my garage and easy attachment and removal per use. I would appreciate your insights to help me make an intelligent purchasing decision. Thank you.
