How does the toothed design affect cutting and mulching?

The toothed profile helps lift and shear grass more aggressively than a standard straight blade, improving clipping suspension for even discharge and finer mulch when conditions allow. It’s useful when you want a balance between bagging and mulching without swapping blades frequently.

• Tooth edges increase lift for cleaner cuts and improved grass suspension.
• Serrated pattern helps break clippings into smaller pieces for faster decomposition.
• Not a guaranteed solution for all turf types—match blade style to mowing goals.

What are the physical specifications and installation notes?

Each blade is 18" long, 2.5" wide at the cutting edge, and 0.197" thick with a 1/2" center hole to accept standard Toro spindles. Installation is straightforward, following manufacturer torque and safety guidelines to maintain balance and avoid vibration.

• Blade length: 18 inches; center hole diameter: 1/2 inch.
• Material thickness: 0.197 inches; width at cutting edge: 2.5 inches.
• Install one blade at a time, torque to mower manufacturer specs, and check blade balance after mounting.

How long can I expect these replacement blades to last?

Blade lifespan varies with lawn conditions, contact with debris, and sharpening frequency. As a general guide, expect months to a few seasons of service for residential use; keep an eye on edge condition and balance for best results.

• Sharpen or replace when edges are nicked or cutting performance declines.
• Avoid cutting over rocks and hard objects to extend blade life.
• Store blades dry and inspect for cracks or bends before each mowing season.

Who is this for? Lawn owners with compatible Toro 52" decks who need a cost-effective, ready-to-install replacement blade set. This 3-pack suits homeowners and small-property landscapers who prefer carrying spares for fast swaps, want improved mulching capability from a toothed profile, and need parts matching several Toro OEM numbers for vintage and newer TimeCutter and Groundmaster models.
