Our Story
Our founders—Kent Harstad and Chris Roehlk—have a combined 60 years of experience in the industry. When they formed the company in 2004, their goal was simple: Give heavy equipment operators the reliable safety and convenience systems they need to save time, stay safe and keep their vehicles working as hard as they do.
Since then, our customers have come to value our reliability, quality workmanship and superior service—which is why most of our business comes from referrals. Companies know they can count on us to deliver cost-saving installations and maintenance that protects their investments and their people.
We take pride in being the best at what we do.
Our Philosophy
Earn your respect.
We show appreciation to all who have placed their trust in us. We are respectful of each other’s time, treat their equipment well and listen with consideration.

Provide unmatched service.
We are proud to feature Lincoln Automatic Lubrication systems, the respected and trusted leader in its field. Lincoln allows grease to be applied throughout the day – eliminating the need to take equipment offline to do it manually. It saves time and money, and it’s more efficient.

Get the details right.
We have the integrity to do the right thing, especially when no one is looking. We hold ourselves accountable to provide accurate assessments and follow through to completion.

Know our stuff.
We prepare ourselves to bring our expertise to every job. We get to the root of the problem and coordinate with the customer and our team to implement the solution. We’re not here to practice.
