These are the upper and lower chute brackets for raising and lowering the top hood on the BX2750 snowblower hydraulically. I have the 2 brackets and the bolts only. They will not work on my new snowblower, since Kubota changed the design of the chute. $75 plus shipping, or pick up in Sturbridge Mass. They should fit into a USPS large flat rate box for delivery in the continental United States.
