MowerPartsGroup (3) Mower Blades for Exmark Quest 50" Deck E and S Series Replaces 115-5059-03

What It Is

This is a set of three replacement mower blades designed for Exmark Quest 50-inch cutting decks on E and S Series models. They replace the OEM part number 115-5059-03 and are intended for residential or light commercial mowing.

Fitment & Compatibility

• Deck size: Only for Exmark Quest 50" decks. Measure your deck width to confirm.
• Model series: Fits Exmark Quest E Series and S Series with a 50" fabricated deck. Not for other Exmark models (e.g., Lazer Z, Turf Tracer).
• OEM replacement: Directly replaces Exmark part #115-5059-03. Verify your current blade part number on the blade or in your manual.
• Measurements: Blade length should be 20.5 inches, center hole diameter 0.75 inches, with a 1.0-inch diameter center hole with a 0.5-inch offset. Check these against your old blades.
• Quantity: Sold as a set of three—one per spindle.

Key Things to Know

• Installation: Easy bolt-on swap if you have a socket wrench and a blade removal tool. Left-hand threads on some spindles—check before tightening.
• Sharpness: Blades come sharp out of the box but may benefit from a quick edge hone for optimal cut.
• Material: Made from hardened steel; they’re durable but will dull faster if you hit rocks or roots. Resharpenable.
• Balance: Pre-balanced, but always check balance after sharpening to avoid vibration.

Should You Buy It

If you own an Exmark Quest 50" E or S Series and need a cost-effective, direct-fit replacement for OEM blades, this set is a solid buy. It’s a good value for residential mowing with reliable performance, but skip it if you have a different deck size or need heavy-duty commercial blades.
