Manufactured from high-grade steel and heat-treated for superior hardness and wear resistance, this 3-blade set is designed as a direct replacement for part number K5619-34330—note that the center hole must be 7\/8\" to fit correctly. Always verify the hole diameter on your existing blades before ordering, since Kubota used multiple center-hole sizes across models.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these XHT blades improve cut quality and durability?\u003c\/h3\u003e\n\u003cp\u003eThese blades are made from premium alloy steel and receive a hardness-focused heat treatment to hold an edge longer and resist bending.
