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 auto, truck, trailer repairs and tires, sales of Hiniker snowplows, Hustler mowers, and LS tractors. 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.

Our new reefer and dry van trailer washout is open! Located at 2095 Business Highway 30 (exit 204) in Tama, Iowa. Hours are Monday-Friday, 7 a.m.-6 p.m., Saturdays

This location will also be the future home of Z Line and we will offer tire sales and service and auto, truck and trailer repairs.
