What It Is

This is a set of three aftermarket mower blades designed to replace OEM part numbers 115-5059-03, 142-6453-S, 110-6837-03, and 112-9759-03. They fit 50-inch cutting decks on Toro TimeCutter, Exmark Quest, and several other zero-turn mowers.

Fitment & Compatibility

Before buying, confirm your deck is exactly 50 inches—not 48 or 54. Compatible models include Toro TimeCutter SWX5050, MX5050, MX5060, 75755, 775750, 75759, 74731, and Exmark Quest SWX5050. Measure your existing blade length (should be ~20.5 inches), center hole diameter (usually 1 inch), and thickness (about 0.25 inches). Aftermarket blades may have slight differences in air lift or edge profile compared to OEM, but fitment is generally direct.

Key Things to Know

• Installation: Straightforward—remove old blades with a socket wrench, torque new ones to 70–90 ft-lbs. Use a blade balancer after installation.
• Quality: Typically made of hardened steel with a coated edge for durability. Expect performance similar to OEM, though some users report slightly faster wear in heavy grass.
• Common gotcha: Verify blade orientation—lift wing should point upward toward the deck. Reversing can cause poor cutting or vibration.
• Set includes three blades: One for each spindle on the 50-inch deck. Replacing all at once ensures even cutting.

Should You Buy It

If you own a Toro TimeCutter or Exmark Quest with a 50-inch deck and want to save money over OEM blades without sacrificing basic performance, this set is a solid choice. Avoid if you need exact OEM fit or are cutting very thick, wet grass regularly—then OEM may last longer.
