The scientists over at Grind Hard Plumbing Co are in full winter mode. Their latest creation brings together a Polaris sport quad and a dirt bike Timbersled snow kit. If it’s your first time hearing about Grind Hard, then you’re probably asking, “Why do such a thing?” Our advice is don’t ask, just enjoy. These boys aren’t confined by the same creative spaces as most people. They do whatever they want, and that includes reinventing the already perfected machine that most of us know as a snowmobile.
