8TEN LawnRAZOR Blade Set for Toro Quest S Series Time Cutter Z 50 Deck 115-5059-03 (High Lift) 3 Pack

What It Is

This is a 3-pack of high-lift replacement blades designed for Toro Zero Turn mowers with a 50-inch cutting deck, specifically the Quest S Series and TimeCutter models. The high-lift profile increases airflow for superior grass discharge and bagging performance compared to standard blades.

Fitment & Compatibility

Before buying, confirm:

• Deck size: 50-inch deck only (not 42", 44", 54", or 60").
• Model compatibility: Toro Quest S Series (e.g., 75742, 75744) and TimeCutter Z (e.g., 75750, 75755) with 50" deck. Check your serial number against Toro’s parts list.
• OEM part cross-reference: Replaces OEM Toro 115-5059-03. Also fits aftermarket decks using that OEM number.
• Blade measurements: Each blade is 20.5 inches long, 0.203 inch thick, with a 5-point star center hole (1.0" across flats). Measure your existing blade length and center hole shape to verify.
• Not compatible with Toro Z Master, Groundsmaster, or any non-50" deck.

Key Things to Know

• Higher lift means more suction: Excellent for thick, damp grass and bagging, but may increase engine load slightly and wear faster in sandy or rocky yards.
• Installation is straightforward: Jack up deck, block securely, remove center bolt (likely 5/8" or 15/16" socket), swap blades, torque to 60-80 ft-lbs. Always check blade balance after install.
• Common gotcha: The star center hole must align perfectly with your spindle’s drive pins. If your spindle has a round hole with a separate key, these blades won’t fit.
• Sharpening tip: Don’t sharpen beyond 1/4 inch of the blade edge—high-lift blades lose performance if the lift angle is altered.

Should You Buy It

If you own a Toro Quest S or TimeCutter Z with a 50" deck and want improved bagging or side-discharge performance in tall or wet grass, this set delivers solid value at roughly $10.66 per blade. It’s a direct replacement for OEM 115-5059-03, so fitment is guaranteed for those models. Not ideal for mulching-only users or owners of smaller/larger decks.
