Culvert-cleaning Attachments
Harr Technologies offers culvert-cleaning attachments for HDD machines. The barrel reamer with fins and water jets rotates through the clogged culvert pipe, mixing water with the debris inside. The push or pull bucket then is used to remove the material. The square box bucket functions like the pull bucket but cleans the sides of box structures more effectively. The brush attachment cleans the crevices of the culvert. The company manufactures 52 varieties of the five attachments, which range in size from 6 inches to 110 inches.
