Fismiuta High-Lift Mower Blades 3-Pack for 50" Zero-Turn Decks — 17.5" Pre-Sharpened, High-Carbon Steel

Fismiuta 115-5059-03 high-lift mower blade set is a 3-pack of pre-sharpened, high-carbon steel replacement blades designed for 50-inch zero-turn decks including many Toro TimeCutter and Exmark models.

These replacement blades are built to restore cutting performance and improve grass collection on mowers that accept the 17-1/2" length, circle center hole, and high-lift profile. Each blade is tempered for strength, treated to resist rust, and balanced to run smoothly on high-speed decks. Use this set when you need a durable OEM-style swap for worn, bent, or damaged blades.

Will these blades fit my Toro TimeCutter or Zero-Turn mower?

They are compatible with a broad list of Toro TimeCutter and similar zero-turn models that take a 17-1/2" high-lift blade with a circle center hole. Check your mower’s parts manual or measure your existing blade to confirm length, width, thickness, and center hole style before ordering.

• Blade dimensions: 17-1/2" length, 2-1/4" width, 1/6" thickness, 29/32" air lift height.
• Replaces Toro OEM numbers: 115-5059-03, 110-6837-03, 112-9759-03 and related references.
• Listed compatible models include many TimeCutter and Z-series machines and a range of Exmark 50" part numbers.

How do high-lift blades help my mowing and bagging performance?

High-lift blades are shaped to generate stronger airflow beneath the deck, lifting grass blades upright for a cleaner cut and more efficient movement of clippings. That increased airflow helps with bagging and side-discharge efficiency, particularly when tackling tall or dense grass.

• Angled blade design increases suction for better grass pickup into bags.
• Sharp pre-honed edges deliver cleaner cuts that reduce tearing or fraying.
• Balanced construction minimizes vibration for smoother operation.

What materials and treatments are used for durability?

Fismiuta blades are made from high-carbon steel and undergo heat treatment to achieve a balance of hardness and toughness. After tempering, they receive rust-inhibiting coatings and baking to protect the finish, helping the blades last longer in outdoor conditions.

• High-carbon steel for edge retention and wear resistance.
• Tempering for impact toughness to resist chipping and bending.
• Painted and baked finish with corrosion inhibitors to extend service life.

How easy is installation and what should I check after fitting them?

Installation follows the same process as other deck blades: secure each blade to its spindle with the correct bolt torque and rotation orientation. After installing, verify blade clearance, balance, and that blade bolts are tightened to the manufacturer’s specifications before first use.

• Pre-sharpened blades reduce time spent on initial sharpening.
• Confirm blade rotation direction and tightness per mower manual.
• Test run at low speed to check vibration and re-torque bolts after a short break-in ride.

Who is this for: The Fismiuta 115-5059-03 3-pack is intended for homeowners and landscapers who own 50" deck Toro TimeCutter, compatible Toro Z-series, or certain Exmark mowers needing high-lift replacements. It’s a practical upgrade for anyone who bags frequently, cuts tall or heavy turf, or needs a rugged, pre-sharpened blade set to restore cutting performance quickly. Always verify compatibility with your specific mower model and OEM part numbers before purchase.
