Not sure who makes the one that is on the OP's tractor, but Firebird Fiberglass in Glendale, Az makes a very good fiberglass unit. I have been hauling tractors with these canopies for over 20 years and have not had any issues. I hauled some for over 200 miles at freeway speeds. the ones for the B series run right at $500 and the L & M series are at $600. They clamp to the ROPS uprights and take less that 30 minutes to install.
