ZALANA High-Lift Replacement Mower Blades for Toro 50" TimeCutter – 3-Pack, 17.5" Heavy-Duty Fit

ZALANA high-lift replacement blades are heavy-duty, 17-1/2" mower blades engineered to restore lift, clipping performance, and bagging ability on 50-inch Toro TimeCutter and compatible zero-turn decks.

These replacement blades are built as direct-fit, high-lift alternatives to Toro OEM parts (115-5059-03, 110-6837-03, 112-9759-03 and related numbers). They match the original center hole, overall length and thickness so you can reinstall them quickly and regain the airflow and cutting action your 50" deck needs for a cleaner cut and improved clippings evacuation. The set contains three identical blades—enough for a full 50" three-blade deck.

Which mower models and part numbers do these blades replace?

They are made to fit many Toro TimeCutter and related 50-inch models across several years, plus some Lawn Boy high-lift applications. Check your deck size and serial number range to confirm compatibility before ordering.

• Replaces OEM: Toro 115-5059-03, 110-6837-03, 112-9759-03 and equivalents (142-6453-S, 79016P).
• Fits 50" Toro TimeCutter models including MX5060, SS5000, SS5035, MX5000, MX5050, MX5025 and Z-series Z5000–Z5060.
• Also compatible with Lawn Boy Z3500 HLX and multiple Toro part number groupings listed in product fitment.

How do these high-lift blades affect cutting and bagging performance?

High-lift blades are shaped to pull more air under the deck, which lifts grass into the blade’s path for a cleaner, more even cut and better discharge into a bagger or chute. You’ll notice stronger suction for bagging and improved mulching action when deck conditions permit.

• High-lift profile increases airflow for better bag fill and discharge.
• Sharp cutting edge length and correct pitch help even, consistent cuts.
• Designed to reduce clogging on heavier, lush turf when paired with a matched deck and spindle condition.

What are the blade dimensions and build quality?

These blades replicate the OEM dimensions so they fit standard 50" three-blade decks without modification. They are stamped from heavy-gauge metal and heat-treated for durability; thickness and hole size match factory specs for secure mounting and proper blade-to-deck clearance.

• Length: 17-1/2"; Width: 2-1/4"; Thickness: 0.187".
• Center hole: round 5/8"; air lift notch approx. 29/32"; cutting edge length ~3-15/16".
• Pack includes three identical blades (3-pack) for a full 50" deck replacement.

How easy is installation and what safety steps should I take?

Installation is straightforward for anyone comfortable with basic mower maintenance. Use the proper socket or wrench to remove blade bolts, match orientation of the new blades, and torque to the manufacturer’s specification. Always work with the mower engine off, spark plug disconnected, and the deck fully supported.

• Remove old blades with mower engine off and spark plug disconnected.
• Install blades with the correct lift orientation and torque bolts to spec.
• Inspect spindles and hardware; replace any damaged bolts or washers for safe operation.
