How do the blade dimensions and mounting details compare to the OEM parts?

UDC Parts 601124 blades match the key measurements most technicians use to verify fit: overall diagonal length, cutting edge length, center hole circle and air lift. The blade length and hole pattern are made to the same specs so the blades sit correctly under a 54" deck and align with the spindle hardware.

• Overall diagonal length: 18-1/2".
• Blade width: 2-1/2"; cutting edge length: 4-23/32".
• Center hole circle: 5/8"; air lift: 31/32"; fits 54" decks.

What does "low lift" mean and when should I choose these blades?

Low-lift blades move less air than high-lift designs, which reduces suction and minimizes clumping when cutting short, dry turf or mowing near light debris. Choose these low-lift blades when your mowing conditions favor a cleaner finish without excessive grass throw, or when your deck design calls for a low-lift profile.

• Lower suction reduces material buildup under the deck.
• Cleaner discharge and suitable for bagging/side-discharge with minimal lift needs.
• Ideal for shorter, well-manicured lawns and routine maintenance mowing.

How many blades are included and what should I check before installation?

This listing includes three identical replacement blades — enough to service most 54" three-blade decks in one job. Before installing, inspect your spindles, blade bolts, and the deck for wear, and confirm the OEM number or model ID to ensure compatibility.

• Pack quantity: 3 blades (fits most 54" three-blade decks).
• Confirm mower model and OEM part number against the compatibility list.
• Replace mounting hardware if bolts or washers are worn; torque to the manufacturer’s spec.
