8TEN LawnRAZOR Mower Blade Set for Toro TimeCutter Z420 Z4200 Z4202 ZS4200 ZS4202 Z530 106-2247-03 (High Lift)

What It Is

This is a set of three high-lift mower blades designed to replace OEM part 106-2247-03 on select Toro TimeCutter zero-turn mowers. High-lift blades create stronger airflow for superior grass clipping discharge and bagging performance, especially in thick or wet grass.

Fitment & Compatibility

• Check your deck size: These blades fit 42-inch cutting decks only. They will not fit 50-inch or 60-inch decks.
• Confirm your model: Compatible with Toro TimeCutter Z420, Z4200, Z4202, ZS4200, ZS4202, and Z530. Verify your model number on the mower’s data tag.
• OEM replacement: Directly replaces Toro part 106-2247-03. Does not require adapters or modifications.
• Measurements: Blade length is 16.25 inches, center hole is 1 inch, and thickness is 0.203 inches. Measure your current blade to confirm.
• Aftermarket note: This is not an OEM Toro blade, but it is designed to match OEM specs. Check that your mower is not under warranty where OEM parts may be required.

Key Things to Know

• Installation difficulty: Easy. Requires a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). Use thread locker on blade bolts.
• Lift effect: High-lift blades increase suction, which improves bagging and side discharge but may reduce fuel efficiency slightly and create more noise.
• Quality: Made from heat-treated boron steel. Users report good durability and sharpness out of the box, but some note the coating can wear faster than OEM.
• Common gotcha: High-lift blades can cause the mower to “walk” or pull sideways on slopes. Not ideal for flat mulching—stick to mulching blades if you bag rarely.

Should You Buy It

If you own a compatible Toro TimeCutter with a 42-inch deck and frequently bag or side-discharge in heavy grass, this is a solid, budget-friendly upgrade over standard blades. Skip it if you primarily mulch or mow on steep slopes, where the extra lift can cause handling issues.
