Upgrade your mowing with Grasscool TCU15881 blades

Grasscool delivers a 3-blade pack engineered for steady, efficient cutting on 60" zero-turn tractors. These 21-inch, high-lift blades are designed to work with a broad range of Z-series and X-series models, helping you tackle lawns, fields, and rougher terrain with confidence. The blades feature a durable 0.250" thickness and a circle center hole for a secure, balanced fit that stays true as you work.

What’s included and key specs

• Package includes 3 high-lift mower blades ready to install
• Blade length: 21 inches; width: 3 inches; center hole: 7/8 inch; thickness: 0.25 inches
• Circular center hole for consistent mounting and balance

Performance highlights

• 2-in-1 design supports both bagging and side discharge in one blade
• High-lift geometry creates strong airflow to propel clippings toward the bag or chute
• Painted cutting edges help resist rust and protect during installation; paint wears naturally over time
• Rigorous testing across hardness, bending, balance, and field performance to ensure reliable cutting

Real-world use and compatibility

These blades are designed to handle overgrowth, rugged terrain, and wet conditions while aiming for a neat, even cut on regular lawns with the right sharpening cadence. They’re compatible with a broad set of turf and tractor models beyond Grasscool, including X400, X465, X470/X485/X495 and many Z-series 60" zero-turn tractors. This broad compatibility helps you select a single blade family for multiple machines, reducing the need for frequent replacements.

While results can vary by mowing conditions and maintenance routines, you may notice faster mowing speeds and efficient clippings management with the right mounting and sharpening intervals. These details are intended to give you a clear sense of possibilities rather than guarantees.

Quality and testing

Grasscool subjects blades to a suite of tests—Rockwell hardness, V-bend, blade chip, balance, performance, and field tests—to support dependable cutting performance across seasons and conditions.
