FAQ

These blades are designed for Toro TimeCutter 50" decks, including models SS5000, SS5060, MX5000, MX5050, MX5060, Z5000, Z5020, Z5030, Z5035, Z5040, and Z5060. They are also compatible with Exmark Quest S and E series mowers.
These blades serve as a direct replacement for Toro OEM part numbers 115-5059-03, 110-6837-03, 112-9759-03, 142-6453-S, 94-1861-03, and 79016P.
Each blade measures 17.5 inches in length, 2.2 inches in width, and 0.177 inches in thickness, featuring a 5/8-inch center hole.
You should replace your blades if you notice the grass tips are turning brown or appearing frayed after mowing, which indicates the blades are dull. Additionally, inspect the blades for deep gouges, bent edges, or significant metal loss from sharpening; if the blade is structurally compromised, it must be replaced for safety and cut quality.
To replace these blades, you will typically need a socket wrench (usually 5/8" or 15/16" depending on your specific spindle bolt), a block of wood to wedge the blade and prevent it from rotating, and a torque wrench to ensure the bolts are tightened to the manufacturer's recommended specifications.
Always disconnect the spark plug wire before working under the deck to prevent accidental engine starting. It is also recommended to wear heavy-duty gloves to protect your hands from the sharp edges of the old and new blades.
