The Cat Low lift Mower blade is excellent for coastal and sandy conditions. The low lift design is less abrasive so it picks up less sand and dust during the mowing process. This blade type works well with Bermuda, Zoysia, and Centipede grass types. The blade is made of steel and only weighs 1.15 lb. The blade has a tri-blade design to provide a quality cut for all 3 cutting modes on the Cat lawnmowers. This blade is compatible with the DG670, DG670.9, DG671, and DG672.9.
