115-5059-03 Mower Blades for 50'' Cut Toro TimeCutter Z Series Mowers Replaces OEM no. 110-6837-03 112-9759-03

What It Is

This is a set of three 50-inch replacement mower blades for Toro TimeCutter Z Series zero-turn mowers. Designed for medium-to-large residential lawns, they cut grass cleanly and evenly when used on compatible decks.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch cutting deck—this set will not fit 42-inch or 60-inch decks. It replaces OEM part numbers 110-6837-03 and 112-9759-03, and fits Toro TimeCutter Z models such as the Z5000, Z5500, Z5600, and Z5700 (check your specific model number on the mower’s serial tag). Each blade measures 17.5 inches long, 2.5 inches wide, with a 0.203-inch thickness and a 5-point star center hole—verify these dimensions against your old blades if you’re unsure. These are genuine Toro blades, not aftermarket, so fitment is exact.

Key Things to Buy

• Quality: Genuine Toro steel with heat-treated edges for durability; should last 25–50 hours of mowing depending on conditions.
• Installation difficulty: Easy—requires a socket wrench and jack or lift to access the underside. Torque blade bolts to 70–90 ft-lbs (check your manual).
• Common gotchas: Always replace all three blades at once for balanced cutting. Inspect the deck’s spindle assembly for wear or damage while the blades are off. Do not sharpen beyond 1/8-inch of the original edge or the blade may weaken.
• Storage: Keep blades dry and oiled to prevent rust if storing for off-season.

Should You Buy It

Yes, if you own a compatible Toro TimeCutter Z with a 50-inch deck and want a direct OEM replacement. It’s a reliable, correctly-fitting option at a fair price for regular residential use—just confirm your model number and deck size before ordering.
