KITONLA AR400 Heavy Duty Replacement Rotary Cutter Blades 14" x 2-3/8" (2-Pack) — 30mm+ Mount, 1/4" Thick

KITONLA Heavy Duty AR400 replacement rotary cutter blades — a 2-blade set sized 2-3/8" x 14" x 1/4" with a 30mm+ mounting hole built for robust mowing and brush-cutting tasks.

These KITONLA blades are engineered as direct-fit replacements for many popular implement and skidsteer-mounted rotary cutters, offering AR400 abrasion-resistant steel for extended life. They’re intended for use on equipment from leading manufacturers and designed to restore clean cutting performance to worn or damaged decks. Durable construction, straightforward mounting, and broad compatibility make them a practical spare for field crews, rental fleets, and property owners who maintain rough vegetation.

Will these blades fit my mower or skidsteer rotary cutter?

Compatibility is broad but check the blade size and hole diameter before ordering. These blades measure 2-3/8" wide by 14" long and are 1/4" thick with a mounting hole slightly larger than 30mm, matching many common Bush Hog-style rotary cutter setups.

• Fits implements from John Deere, Kubota, Bobcat, Case, Caterpillar, ASV and more.
• Designed for skidsteer, skid loader, compact track loader and implement applications.
• Confirm your deck uses a 14" blade length and 30mm+ center hole.

How do these AR400 blades perform on heavy brush and tall grass?

The AR400-grade steel provides higher abrasion resistance than standard carbon blades, helping edges keep their shape when encountering abrasive stalks, sand, and small limbs. While not indestructible, they deliver reliable cutting consistency and longer service intervals under demanding conditions.

• AR400 steel resists wear for more cuts between sharpenings.
• 14" length balances reach and durability for typical cutter decks.
• Robust 1/4" thickness reduces bending and breakage risk.

Can I install these replacement blades myself and what tools are needed?

Yes — installation is straightforward for anyone comfortable with basic mower service. Remove the old blades, match orientation, slide the KITONLA blade onto the spindle using the 30mm+ hole, and torque fasteners to the manufacturer’s specification.

• Typical install time: a few minutes per blade for a competent user.
• Use appropriate wrenches, locking tools, and safety supports for the deck.
• Always follow the machine manufacturer's torque and safety instructions.

What maintenance tips extend blade life?

Routine care keeps cutting performance steady and prolongs service life: inspect after heavy impacts, remove built-up debris, and sharpen only when needed. Replace blades when cracks, severe bends, or major edge loss occur rather than risking equipment or poor cut quality.

• Check blades after striking rocks or stumps for damage.
• Clean off mud and plant material to reduce corrosion and wear.
• Sharpen edges evenly; maintain balance to avoid vibration.

Who is this for: These KITONLA AR400 replacement rotary cutter blades suit professional landscapers, contractors, farmers, and property owners who run skidsteer or implement-mounted rotary cutters and need a durable, cost-effective spare. If you operate equipment from brands such as John Deere, Kubota, Bobcat, Case, Caterpillar, ASV or Mower King and require a 14" blade with a ~30mm mounting hole, this 2-blade set provides a practical solution to restore cutting performance and reduce downtime.
