How do these toothed blades improve cutting and mulching?

The blade profile and toothed edges help create finer clippings circulation under the deck, promoting quicker grass recycling and a more even appearance. Sharp, aggressive teeth lift and shear clippings more effectively than worn straight blades, which reduces clumps and improves dispersion.

• Toothed cutting edge agitates clippings for better mulching action.
• Improved lift and shear helps produce uniform cut and faster decomposition of clippings.
• Durable metal construction holds an edge longer than factory-worn blades.
• 3-blade set ensures full coverage for a 50" deck replacement.

These ZALANA blades are built from heavy-duty steel with specifications that match the original Toro replacements, so they fit and perform without modification. Knowing the key measurements helps confirm fitment for your deck and spindle configuration.

What should I expect for installation and after-sales support?

ZALANA offers short-term warranty coverage and customer support if there are fitment or quality concerns after purchase.
