I'm planning to upgrade my Z421's blades to Gator blades. Does anyone know the correct part numbers? What length and diameter should I choose?

Did you end up upgrading the blades since you posted last October? For the Kubota Z421, which typically runs a 54-inch deck, the Gator blade part number that matches up is often listed as K5613-34340 or K5613-34342 depending on the supplier and blade style. These blades are usually 18 inches long each and the center hole diameter is 5/8 inch, which fits the spindle on the Z421. You'll want to confirm the exact deck size and blade count on your mower before ordering, since some Z421 models have slight variations depending on the year and configuration. If you're still deciding, are you looking for high-lift performance or more mulching capability with the upgrade?
