IDEASURE mulching blades for 60" mower deck – 3‑pack 20.5" length, 5/8" center hole, heavy‑duty steel

IDEASURE 103-0301 mulching blades are a 3-pack of heavy‑duty, single‑piece steel replacement blades designed to restore even, efficient mulching performance on 60" mower decks.

These replacement blades are made to match common OEM fitments for commercial and residential zero‑turn and riding mowers. Each blade measures 20-1/2" long, 2-1/2" wide and 0.203" thick with a 5/8" center hole, so they provide the cutting reach and stability needed for 60" decks. The set replaces several part numbers across popular brands, giving you an economical option to bring worn or damaged blades back to factory‑style performance.

Will these blades fit my Ex-Mark Lazer Z or similar mower?

These IDEASURE blades are built to replace Ex-Mark part numbers like 103-0301 and 103-2530 and match the bolt pattern and dimensions of many 60" decks. Compatibility extends to a range of Ex-Mark Lazer Z models as well as other brands that use the same spec. Always compare the blade length, thickness and center hole to your original blade before ordering.

• Fits 60" mower decks with 20-1/2" blade length
• 5/8" center hole matches standard spindle bolts
• Replaces OEM numbers including 103-0301, 103-2530, 633483
• Compatible with Lazer Z AS/LC/XP/XS and similar models

How do these blades improve cutting and mulching?

The blades are formed from a single piece of thick steel for consistent edge geometry and reduced flex during operation. Their mulching profile helps lift and circulate clippings for finer cutting and better grass recycling. That results in a neater discharge and improved appearance without drastically slowing mowing speed.

• Thick steel construction for reduced vibration
• Mulching profile promotes finer clipping circulation
• Balanced design for even cutting across the deck
• Durable edge resists premature wear and dulling

What are the exact specifications I should confirm before buying?

Measure your existing blade and spindle before purchasing to ensure an exact fit: length, width, thickness and center hole diameter are critical. Check your mower’s parts manual or the old blade’s stamped part number against the replacements listed here to confirm compatibility. If anything differs, replacement blades may not seat correctly or could cause vibration and poor cutting.

• Blade length: 20-1/2"
• Blade width: 2-1/2"
• Thickness: 0.203"
• Center hole: 5/8" (0.625")

How should I install and maintain these blades for best life?

Installation requires proper torqueing of the spindle nut and ensuring the blade orientation matches the original cutting edge and lift. Balance new blades against one another to avoid vibration; mount all three blades supplied in the pack as a matched set when replacing a full deck. Keep blades sharp and inspect for bends or damage after hitting debris to maintain performance and safety.

• Torque spindle nuts to manufacturer specs
• Install blades with correct cutting orientation and lift
• Balance blades as a matched set to prevent vibration
• Sharpen and inspect blades regularly for safety and finish
