110-6837-03 Mulching Blades Compatible with Toro TimeCutter Z 5000 Series 50" Deck, 112-9759-03 Mower Blades, Replace for 112-9759, 115-5059-03, 115-5059, 3 Pack

What It Is

This is a set of three mulching blades (part number 110-6837-03) designed for Toro TimeCutter Z 5000 Series zero-turn mowers with a 50-inch cutting deck. They replace OEM blades 112-9759-03, 115-5059-03, and 112-9759, and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

• Deck size: Fits Toro TimeCutter Z 5000 Series with a 50-inch deck only. Not for 42-inch or 60-inch decks.
• Model check: Verify your mower model number (e.g., 74799, 74800) in the owner’s manual or under the seat. This blade set does not fit MyRIDE or other Toro series.
• OEM vs aftermarket: These are aftermarket blades, not genuine Toro. They match OEM dimensions but may vary slightly in thickness or balance.
• Measurements: Each blade is approximately 16.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch offset. Confirm your existing blade’s length and hole size before ordering.

Key Things to Know

• Mulching only: These blades have a curved, high-lift design for mulching. They will not bag or side-discharge effectively. Use dedicated bagging blades if you need that function.
• Installation: Simple swap—remove the center bolt (usually 5/8-inch or 15/16-inch socket), replace blade, and torque to 70–90 ft-lbs. No special tools beyond a socket wrench and a block of wood to hold the blade.
• Sharpness out of box: Blades come sharp but may need a quick touch-up after first use to remove burrs. Check balance after sharpening.
• Common gotcha: Some users report the blades are slightly thinner than OEM, which can cause vibration if not perfectly balanced. Always balance new blades before installing.

Should You Buy It

Buy this set if you own a Toro TimeCutter Z 5000 with a 50-inch deck, primarily mulch your lawn, and want a cost-effective alternative to OEM blades (typically $15–20 each). Skip it if you need bagging or side-discharge performance, or if you prefer guaranteed OEM fit/finish. For $31.99 for three, it’s a solid value for frequent mulchers.
