Z Line Ltd. was started as Randy Zimmermann Trucking in 1976 with a single semi and grain trailer. The fleet has grown to 40+ trucks and our transportation division is now partnered with Don Hummer Trucking. Our services have expanded through the years to include  truck and trailer repairs, auto, truck, trailer, ag and commercial tires, reefer and dry van washouts, sales of Hiniker and SnowEx snowplows, and Hustler mowers. We are a family owned company with Randy's wife Connie, daughter Brandi and son Jared helping him with operations, along with our extended family of employees and drivers.

We have completed our move to our new location at 2095 Business Highway 30 in Tama, Iowa. All services-auto, truck & trailer repair, tire repair and trailer washouts and sales-LS tractors, Hustler mowers, Hiniker and Snow Ex snowplows are now located at our new facility.
