8TEN LawnRAZOR Blade Set for Toro Quest E Series 34 Deck 115-5059-03 (High Lift) 2 Pack

What It Is

The 8TEN LawnRAZOR Blade Set is a high-lift aftermarket blade replacement for Toro Quest E Series mowers with a 34-inch cutting deck. It’s designed for improved grass discharge and bagging performance, especially in thick or tall grass.

Fitment & Compatibility

• Deck size: 34-inch Toro Quest E Series deck only. Measure your deck width to confirm.
• Model/brand fit: Replaces OEM Toro part 115-5059-03. Fits Toro Quest E Series models like 22038, 22039, 22040, and similar (check your model number under the seat or on the frame).
• Aftermarket note: 8TEN is a third-party brand, not Toro OEM. Dimensions and hole pattern match the original, but verify blade length (approx. 16.5 inches) and center hole size (1 inch) before buying.
• What to check: Compare your old blade’s length, width, and hole diameter. Also confirm your mower uses two blades (this is a 2-pack) and that you don’t need a different lift style (e.g., standard vs. mulching).

Key Things to Know

• Quality: High-lift design produces strong airflow for better bagging and side discharge, but can wear faster on sandy or rocky lawns.
• Installation: Straightforward swap with a socket wrench. Use a blade removal tool or block the blade to prevent spinning. Torque bolts to 70-90 ft-lbs (check your manual).
• Common gotcha: High-lift blades increase engine load and noise slightly compared to standard blades. Not ideal for dry, dusty conditions or frequent mulching.
• Balance: Each blade should be balanced after installation (a $10 balancer from any hardware store) to prevent vibration and deck damage.

Should You Buy It

Buy this set if you own a Toro Quest 34-inch mower and want better bagging or side-discharge performance for thick grass—especially if you’re replacing worn OEM blades on a budget. Skip it if you primarily mulch or mow in dusty/dry conditions, or if you prefer OEM parts for warranty peace of mind.
