AG repair is on the business’s own description for a reason. Black Hawk County is farm country, and the same heavy diesel, hydraulic and electrical skills that fix a semi fix a combine.

Harvest does not pause for a shop schedule. A machine down in the field during a dry window costs a real number per hour, and everybody involved knows it. Field service means the repair happens where the machine sits, with the tooling brought to it.
The work is familiar. Hydraulic leaks and hose failures, electrical faults and harness damage, charging and starting problems, air and brake work on grain trailers, tires and wheel ends. Farm equipment is harder on wiring and hydraulics than a highway truck, not easier.
Grain hauling season also puts trucks and hopper trailers on the road that spend most of the year parked. Lights, brakes and tires on those units are the single most common thing found and fixed before an officer finds them instead.
