Rotary 3-pack 3401 replacement blades provide durable, OEM-compatible cutting performance for Bobcat 112111-02, Gravely 03253800 and Wright models, sized to match 36", 52" and 54" decks.

These three 3401 blades from Rotary are made to restore cutting efficiency and deck balance on multiple zero-turn and stand-on mowers. Engineered to match the hole pattern and dimensions of the referenced OEM parts, the set is a direct-fit replacement for popular Bobcat, Gravely and Wright part numbers. Whether you need a single deck refresh or routine seasonal maintenance, this blade pack simplifies replacement and helps maintain even, consistent clippings.

Will these blades fit my mower deck and mounting pattern?

The Rotary 3401 blades match the bolt pattern and dimensions of Bobcat 112111-02, Gravely 03253800 and Wright 71440004/71440009-0. Confirm your deck size and whether your mower requires three blades for your specific deck (for example, a 52" deck uses three blades). If your original blade has the 3401 profile, these will be compatible.

• Direct-fit for listed Bobcat, Gravely and Wright part numbers
• Available in lengths suited for 36", 52" and 54" decks where applicable
• Sold as a pack of three—ideal for decks requiring multiple blades
• Check blade hole spacing and length against your OEM blade before installing

How do these blades improve mowing performance?

Fresh, correctly matched blades restore a clean cut and reduce uneven grass tearing that leads to brown tips. Balanced blades keep the spindle loading consistent, which preserves deck bearings and spindle life. These Rotary blades are intended to provide a uniform cut pattern and reliable material thickness for prolonged service life.

• Sharp cutting edges reduce turf damage and improve appearance
• Balanced set minimizes vibration and wear on spindles
• Durable steel construction holds edge longer than worn OEM blades
• Pack of three ensures matched blade geometry across the deck

What are the practical steps for replacing and maintaining these blades?

Always disconnect the spark plug and follow the mower manufacturer’s safety procedures before replacing blades. Use the correct socket and torque specs to secure each blade, and verify blade alignment to maintain proper deck balance. After installation, check for any unusual vibration at low RPM and re-torque mount bolts after the first mowing session.

• Disconnect spark plug and stabilize the mower on level ground
• Use manufacturer-recommended torque settings for blade bolts
• Inspect blades periodically for nicks, bends or excessive wear
• Sharpen or replace blades as a matched set to avoid imbalance

Who is this for: This Rotary 3-pack of 3401 blades is intended for homeowners, landscapers, and service shops that operate Bobcat, Gravely or Wright zero-turn and stand-on mowers requiring these OEM-compatible replacements. It’s especially useful for professionals who prefer replacing blades in matched sets to maintain cutting quality and reduce vibration-related wear. Choose this set when you need a reliable, direct-fit swap for routine maintenance, mid-season edge restoration, or when preparing equipment for peak mowing months.
