ZALANA mulching lawn mower blades 50" replacement 3-pack for Toro TimeCutter – toothed, balanced 17-1/2"

ZALANA 110-6837-03 is a heavy-duty three-blade mulching set engineered to restore cutting performance on 50" Toro TimeCutter and compatible decks.

If your mower is leaving uneven clippings or taking longer passes to finish the lawn, fresh mulching blades can make a measurable difference. This ZALANA replacement set matches the OEM hole, length and thickness for direct fit on 50" Toro decks including TimeCutter Z and MX series, SS series, and selected Lawnboy models. The blades are toothed for improved grass lift and mulching action, and they come as a three-pack to service the full 50" deck at once.

How do these ZALANA blades improve mowing quality?

The toothed profile lifts grass more effectively so clippings are cut finer and dispersed evenly, reducing clump formation. Sharper edges and proper blade geometry also reduce the number of required passes, saving time on each mow.

• Toothed cutting edge for better grass lift and circulation.
• Balanced geometry to minimize vibration and uneven cuts.
• Three-blade pack fits the standard 50" deck layout for full coverage.
