116-6358-03 Mower Blades for Toro TimeMaster 30 Inch Deck, Replace 120-9500-03 145-4002-03, Fits Toro TurfMaster & Exmark ECKA30, Mulching Blades 2 Pack

What It Is

This is a set of two mulching blades designed for Toro TimeMaster 30-inch deck mowers and compatible Toro TurfMaster and Exmark ECKA30 models. They replace OEM part numbers 120-9500-03 and 145-4002-03, and are intended for grass clipping recutting and fine discharge.

Fitment & Compatibility

• Deck size: 30 inches only. Will not fit 22-inch, 36-inch, or other deck widths.
• Exact models: Toro TimeMaster (model 21199, 21200, 21201, 21202, 21203), Toro TurfMaster 30-inch (model 30665, 30666), and Exmark ECKA30 (model 4490-440, 4490-441).
• OEM replacement: Direct OEM part number swap for 120-9500-03 and 145-4002-03. Check your current blade’s part number stamped on the blade or in your owner’s manual.
• Measurements: Blade length is 16.25 inches, center hole 0.75 inch, with a 0.5-inch offset. Measure your old blade’s length and hole size before ordering if unsure.
• Aftermarket note: These are genuine Toro blades, not generic. No adapter or modification required for listed models.

Key Things to Know

• Mulching vs. bagging: These blades are optimized for mulching—they have a curved, high-lift design to recut clippings. They will not bag as effectively as standard blades.
• Installation: Requires a 5/8-inch socket and torque wrench (recommended 70-90 ft-lbs). Use a blade stop tool or block of wood to prevent deck rotation. Sharp edges—wear gloves.
• Pair set: Two blades per pack—one for each spindle on a 30-inch deck. Do not use a single blade.
• Common gotcha: These blades are thicker than some aftermarket alternatives. Verify your deck’s blade bolt length is sufficient (standard bolts work for most TimeMaster models). If bolts are too short, use OEM Toro bolts (part 108-7675).

Should You Buy It

If you own a Toro TimeMaster or TurfMaster 30-inch mower and want OEM-quality mulching blades that fit perfectly and last a full season of heavy use, this is a solid buy at $19.99. Skip it if you need bagging or standard discharge blades—these are mulching-specific and will leave clippings on the lawn if bagging is preferred.
