This fire plow is based on the FESCO type, that raises and lowers using the hydraulic cylinder. In this case, once assembled, the hydraulic should move, as well as the piece swivel slightly side to side, but one needs to add chain to the piece to hold it in the up position, or glue it if preferred. The hydraulic cylinder has bumps that slip into corresponding cutouts in the brackets, which will need some careful sanding in order to slide them into place and still create some resistance. Take it slow and easy with these parts! Should there be any questions or issues, contact me via the designer link or directly via email to firstname.lastname@example.org
