JSXDNWYJ 115-2454-03 / 115-4999 mulching blades are a six-pack of direct-fit replacement blades engineered for Toro and Exmark 54" three-blade decks made after 2015.

These mulching blades replace Toro part numbers 115-2454-03, 115-4999, 115-4999-03 and equivalents, offering a direct swap for many Titan, MX and ZX series lawn tractors and select TimeCutter and Exmark platforms. They have the same mounting keyway and dimensions as the OEM parts, letting you restore cutting performance and mulching quality without modification. Read on for fit advice, dimensions, installation tips and who should choose this pack.

Which machines will these blades fit?

These blades are intended for 54" three-blade decks on Toro and compatible Exmark models produced after 2015. They are made to match the OEM footprint and mounting pattern used on specific Titan, MX and ZX series tractors and some TimeCutter HP decks.

• Compatible Toro models: Titan 5400C, MX5400, MX5480, ZX5400, ZX5420, ZX5450.
• Also fits Toro TimeCutter HD 75312TA (54" deck layout).
• Exmark compatibility: Lazer Z E-Series and Turf Tracer X-Series sharing the same 54" three-blade platform.
• Not compatible with single- or two-blade decks, older pre-2015 54" models, or non-US import-spec decks.

What are the exact blade dimensions and mounting details?

Each blade measures 18.75 inches long, 2.25 inches wide and 0.164 inches thick with a 5/8" keyway center hole to match OEM spindles. These dimensions match the listed OEM replacements so blades sit and spin true when installed correctly.

• Length: 18.75" (approx. 476 mm).
• Width: 2.25" and thickness: 0.164" for durable edge retention.
• Center hole: 5/8" keyway to fit standard deck hardware for the specified models.
• Sold as a 6-pack to replace all three blades twice or keep spares on hand.

How should I install and maintain these mulching blades?

Install all three blades on a 54" deck at the same time to avoid imbalance or vibration. Tighten mounting bolts to the original equipment torque and inspect blade orientation so the mulching lips face the correct direction for cutting and clipping circulation.

• Replace all three deck blades at once to prevent abnormal vibration.
• Use OEM-specified mounting bolts and torque values; check hardware condition.
• Sharpen blades periodically and replace if bent, cracked or excessively worn.
• Confirm deck compatibility (post-2015 54" three-blade decks) before ordering.

Who is this for? Choose this JSXDNWYJ six-pack if you own a compatible Toro or Exmark 54" three-blade deck produced after 2015 and need direct-fit mulching blades without modifying your mower. It’s a practical option for equipment owners who prefer to replace all blades together, keep spare blades on hand, or restore mulching performance on Titan, MX, ZX or selected TimeCutter and Exmark machines. If your deck is an older model, a single- or two-blade design, or a non-US import, verify fitment against your deck's part numbers and measurements before purchase.
