We inspect, service, and test all generators that we purchase to ensure that any used generator that you buy from us will be guaranteed to run and provide power in the most critical moments. Woodstock Power Company specializes in buying and selling new, used, replacement, and rental generators, including Katolight generators in good running condition. Katolight generators are a popular choice in the farm and agricultural industries, but have also been a mainstay in many residential and industrial applications as well.
