8TEN LawnRAZOR Blade Set for Toro Time Cutter Z 5000 Series 50" Deck 112-9759-03 (Medium Lift) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade Set is a medium-lift, aftermarket replacement blade pack (3-pack) designed for Toro Time Cutter Z 5000 series zero-turn mowers with a 50-inch cutting deck. It’s intended for regular residential mowing on standard turf, offering a balance of lift and cut quality without excessive power draw.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This set fits only the 50-inch deck on the Toro Time Cutter Z 5000 series. It will not fit 42-inch, 44-inch, or 60-inch decks.
• OEM number: It replaces OEM part 112-9759-03. Check your current blade’s part number or look for that number on your mower’s deck or manual.
• Measurements: Each blade is approximately 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.5-inch spindle hole. Measure your existing blade’s length and hole sizes to confirm match.

This is an aftermarket set, not Toro OEM, but it’s built to the same specs. It will not fit Time Cutter models older than the Z 5000 series or any non-Toro mower.

Key Things to Know

• Medium lift: Good for bagging and side discharge on standard grass. Not ideal for thick, wet, or tall grass—consider a high-lift blade for those conditions.
• Installation: Straightforward swap—remove the center bolt (likely 5/8-inch), replace blade, torque to 70-80 ft-lbs. Use a blade removal tool to lock the spindle.
• Balance check: These are pre-balanced, but always check balance with a blade balancer before installing. An unbalanced blade causes vibration and spindle wear.
• Sharpness: They come sharp but not razor-edged. Expect to sharpen after 8-10 hours of mowing for best cut quality.

Should You Buy It

If you own a Toro Time Cutter Z 5000 series with a 50-inch deck and need a reliable, affordable replacement for standard residential mowing, this set is a solid choice. It’s not for commercial use or heavy-duty conditions, but for typical lawn care, it offers good value—just confirm your deck size and OEM number first.
