How do these blades match my mower’s OEM specifications?

These replacement blades are produced to mirror the key dimensions and mounting hole required by the listed OEM parts. That means the center hole diameter, blade length and thickness follow the same measurements to ensure safe fit and proper deck clearance.

• Length: 18 3/4 inches for proper blade-to-deck clearance
• Width: 2 1/4 inches for standard cutting swath
• Thickness: 0.177 inches for strength and stability
• Center hole: 5/8 inch to match spindle hardware

Which mower models are compatible with these replacement blades?

The blades are intended for 54-inch decks on a range of Toro and Exmark machines. Always compare part numbers and serial ranges before buying to confirm fit for your specific machine.

What performance and installation benefits can I expect?

Replacing dull or bent blades with matched replacements improves cut quality, reduces recoil and vibration, and helps maintain deck balance. These blades are straightforward to install with basic tools and return consistent chopping and discharge patterns when correctly torqued and balanced.

• Heat-treated steel for maintaining a sharp edge longer under normal use
• Consistent thickness and hole alignment for easier installation and reduced vibration
• Can be installed at home with a wrench and basic safety gear
• Multiple blades sold individually or in sets to service a full 54" deck

How should I care for these blades to extend their life?

Routine inspection and simple maintenance keep blades cutting well and prevent damage to the deck and spindle. Replace or regrind when chips, bends or excessive wear appear.

• Sharpen periodically to maintain even cutting and avoid tearing grass
• Balance blades after sharpening to prevent vibration
• Inspect mounting hole and blade center for elongation or cracking
• Store spare blades dry to avoid corrosion
