I just read an article about pro-tech sueing avalanche snowpushers over stealing the same idea. I guess avalanche sent a rep to the pro-tech plant to see their pushers, get a video and literature. then it said they copied their copyright infrigment. At the end of the article it said that they were also investigating other sno-pushers. I think all the others ones out there are in somewayu going to stop production, like avalanche since they violate pro-tech copyright. Daniels might be next who knows. Just wanted to say that.
I really like the metal trip edge design, The only thing I dont like about my Pro-Tech is that it doesnt scrape down to the pavement so I would definitly take a look at the Daniels, Looks like a good idea to me Just my two cents
Cat320- AW Direct has been selling those ones for a while. I think they're the same ones the post office trucks use.
