The Kubota Quick coupler Replacement Kit was designed to change the four into one flat faced coupler with individual pioneer quick couplers. The hydraulic line quick disconnect for the newer Kubota B and BX80 series loaders has had a lot of issues with leaking hydraulic couplers. This kit will use the existing mounting block on the tractor, but will eliminate the 4 into 1 coupler on the loader. The flat faced couplers will be replaced with pioneer style couplers.
