Jake Schmotter
Product and Innovation Director
Jake Schmotter, Director of Engineering and R&D
Jake Schmotter grew up in the small town of Stillwater, Minnesota and graduated from University of Wisconsin – Stout with a degree in Mechanical Engineering. After graduation, he began his career with Polaris Industries. Being raised by a father that was a general contractor, working for him growing up until his college years, he was often found designing and building machine attachments, operating equipment or just figuring out solutions to problems as they arose, a natural problem solver, mechanically inclined with a hands-on, strategic approach.
In 2012 Jake had the opportunity to take on new challenges at Jarraff Industries, LLC. bringing engineering functions in-house and start developing the team. As things started out much of the time was spent on legacy designs, solving problems requiring immediate solutions and accelerated development plans. Throughout the next several years Jarraff expanded rapidly undergoing significant changes in equipment. Amongst the chaos, the team was able to develop and Patent an industry first, rotating saw head for the Mechanical Trimmers. Jarraff industries has a strong belief in product advancement through innovation and continues to expand the engineering group to support exactly that.
In his free time, Jake actively races Superbikes at a semi-pro level in the Central Roadracing Association where he volunteers, safely coaching new riders to become nationally recognized licensed roadracers. He also volunteers his time at local organization, supporting motorcycle awareness and improving riding skills for safety on the public roads. Occasionally he still finds time for local motocross races and enjoys watersport activities, snowmobiling and snowboarding. In his downtime you will typically find him never sitting still and likely building or fixing something of some sort, whether it be a attachment for the skidsteer, race bike part or just the furnace.
