UDC Parts 115-5059-03 Mower Blades Replacement for Toro TimeCutter 50 Inch SS5000 75750 MX5000 75755 MX5060 MX5050 75759 SWX5050 74731 Exmark Quest 142-6453-S 110-6837-03 Zero Turn Lawn Mowers /3 Pack

What It Is

This is a 3-pack of aftermarket mower blades designed for 50-inch zero-turn mower decks, primarily replacing OEM blades on Toro TimeCutter and Exmark Quest models. They are for residential or light commercial mowing where you need a sharp, durable cut without paying OEM prices.

Fitment & Compatibility

Check your deck size: These blades fit 50-inch cutting decks only. Measure your deck width before buying.

Model match: Confirm your mower is on the list: Toro TimeCutter SS5000 (75750), MX5000 (75755), MX5060, MX5050 (75759), SWX5050 (74731), or Exmark Quest (142-6453-S, 110-6837-03). If your model number isn’t listed, measure blade length—these are 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset.

OEM vs aftermarket: These are a direct replacement for OEM part 115-5059-03. They are not OEM Toro blades but match the dimensions and hole pattern. Verify your spindle bolt pattern matches (standard 5/8-inch bolt).

What to check before buying: Measure your current blade length, width, center hole diameter, and offset. If any dimension differs, do not buy.

Key Things to Know

• Quality vs OEM: Made from hardened steel, but may not hold an edge as long as genuine Toro blades. Expect to sharpen or replace more frequently on tough grass or rocky lawns.
• Installation: Easy DIY job if you have a socket wrench and blade removal tool. Torque bolts to 80-90 ft-lbs. Use thread locker to prevent loosening.
• Common gotcha: Blades are sold as a set of three—some mowers use four blades. If your deck has four spindles, you need two packs.
• Balance: Aftermarket blades are often balanced well out of the box, but always check with a blade balancer before installing to avoid vibration and spindle wear.

Should You Buy It

Buy this if you have a compatible 50-inch Toro or Exmark zero-turn and want a budget-friendly 3-pack for regular blade changes. It’s perfect for homeowners who mow weekly and don’t need premium OEM longevity. Skip it if you have a different deck size, need four blades, or mow heavy commercial turf where edge retention is critical.
