If you need replacement parts, contact Beckwith Township about costs. The blades or blue section with the white number will cost $40 to replace. A complete post and blade will cost $140. These are 2018 rates. Beckwith requires a prepayment before they will process any request. They also said that they require a minimum of 10 requests from anywhere in the township before they do a batch run so it won’t be instantaneous.
