What It Is

This is a 12-pack of aftermarket replacement blades designed for 50-inch cutting decks on select Toro TimeCutter Z and TimeCutter Z5000 zero-turn mowers. They’re meant for routine blade swaps on residential or light commercial mowing.

Fitment & Compatibility

• Deck size: Only for 50-inch Toro TimeCutter decks. Measure your deck width—this won’t fit 42" or 60" models.
• Compatible models: Z5000 (74370, 74372, 74373, 74374, 74375, 74376). Also fits some older TimeCutter Z models—check your mower’s model number.
• OEM part numbers: Replaces Toro 110-6837-03, 112-9759, and 115-5059-03. Cross-reference your existing blade’s part number.
• Measurements: Blades are roughly 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset. Measure your current blade to confirm length and hole size.
• Aftermarket note: Not OEM Toro. Quality and balance can vary—check reviews for your specific mower model.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (set to 70-90 ft-lbs), and blade removal tool. Lift mower safely—never work under a raised deck without locks.
• Balance: Aftermarket blades often need balancing before installation. Use a blade balancer to avoid vibration that can damage spindles.
• Sharpening: These are pre-sharpened but may require light honing for optimal cut. Resharpen after 10-15 hours of use.
• Gotcha: 12-pack is for multiple changes—store extras in a dry place to prevent rust. Don’t mix lengths or offsets between blade positions.

Should You Buy It

If you own a 50-inch Toro TimeCutter Z5000 and want a bulk supply for frequent blade changes, this is a cost-effective option. It’s right for DIY owners who can handle basic maintenance and blade balancing. If you prefer OEM fitment or have a different deck size, look elsewhere.
