Important Notes

• Do not assume this blade is specifically a mulching, bagging, high-lift, low-lift, Gator, or combination blade unless confirmed for your equipment
• Compare the original blade’s length, width, thickness, center hole, mounting pattern, cutting profile, lift design, and orientation
• Do not substitute a mower blade based solely on the heavy-duty designation or approximate appearance
• Inspect associated blade adapters, spindles, mandrels, shafts, bearings, pulleys, washers, blade bolts, and mounting hardware for wear or damage
• Check the original blade and spindle system for bending, excessive play, vibration, or impact damage before installing the replacement
• Never attempt to straighten, weld, or repair a cracked or severely bent mower blade for continued use
• Verify whether any blade bolts, washers, adapters, or other mounting hardware are included or must be purchased separately
• Shut off the mower, disconnect the appropriate power source, and ensure all blades have completely stopped before servicing the cutting system
• Use appropriate hand protection when handling mower blades, as the cutting edges may be sharp
• Install the blade in the correct position, orientation, and cutting direction and tighten the mounting hardware according to the equipment manufacturer’s specifications
• After installation, verify proper blade retention, orientation, balance, deck clearance, and unobstructed rotation before returning the mower to normal operation
