X-Blade Dual Mulching Blade Adapter Kit (Exmark – Complete Hardware Kit)
Commercial Mower Performance Upgrade

Stop Guessing. Get Everything You Need in One Kit.

Always verify blade length and center hole size before ordering.

Turn Your Side-Discharge Mower Into a Grass-Pulverizing Machine

The X-Blade Dual Adapter Kit transforms a standard side-discharge commercial mower into a high-performance cutting and mulching system. Designed for professional landscapers, this system delivers better cut quality, improved airflow, and increased efficiency across multiple mowing conditions.

Use our Search by Mower tool to confirm compatibility.

Dual-Blade Design for Maximum Performance

The X-Blade Adapter holds two blades per spindle at a true 90-degree angle:

• Lower blade maintains proper cutting height
• Upper blade increases vacuum and airflow
• Dual cutting action reduces clipping size
• Improves mulching, discharge velocity, and overall cut quality

Clippings are cut multiple times before exiting the deck, resulting in a cleaner, more consistent finish.

Improved Airflow = Better Results

Increased airflow and discharge velocity help your mower:

• Cut cleaner and more evenly
• Process clippings more efficiently
• Improve striping and overall appearance
• Boost productivity in heavy growth and leaf cleanups
• Enhance bagging performance with tighter packing

Cleaner cuts lead to healthier turf and better results for your customers.

One Kit. Multiple Applications.

The X-Blade system improves performance across all cutting modes:

• Mulching: Finer clippings and better breakdown
• Bagging: Increased vacuum for improved lift and packing
• Side Discharge: More controlled, even spread

From weekly maintenance to heavy cleanup jobs, this system adapts to the work.

Professional-Grade Results Without Compromise

Maximize cut quality, mulching performance, vacuum strength, and discharge velocity—without replacing your entire blade system.

Will X-Blades Damage My Mower?

Short answer: No — when used correctly on compatible machines.

The X-Blade bracket holds two blades in a balanced 90-degree configuration. Compatible commercial mowers are built to handle the added rotating mass.

The bracket is also designed to give slightly on impact, helping protect more expensive components like spindles and deck hardware.

Blade Selection Matters

• Use the correct blades for your setup
• Engage/disengage blades at 50–70% throttle
• Only run X-Blades on approved machines

The X-Blade system has been used by contractors for over 10 years, with hundreds of thousands of sets in the field.

Hardware Notes for Exmark

Exmark setups often require longer bolts to achieve proper thread engagement:

• 2 1/2” length
• 1/2” fine thread
• Grade 8

This kit includes the hardware you may need—use only what your mower requires. 

Chute Blocker Note

A chute blocker is not required but can improve:

• Discharge control
• Airflow direction
• Mulching performance (especially in leaves or heavy growth)

When Can You Run X-Blades?

• Leaf cleanups
• Heavy growth seasons
• Or all season long

Blades can also be removed and run as standard single blades at any time.

If you’re looking to improve cut quality, vacuum, mulching performance, and discharge velocity, X-Blades deliver.
