Reliable Aftermarket Parts 20.5" High-Lift Mower Blades Pack of 3 for Dixie Chopper/Gravely 60" Decks, 5/8" Center Hole

High-lift replacement blades: a set of three 20.5" heavy-duty mower blades designed to fit Dixie Chopper and compatible Gravely XXW series 60" decks.

These aftermarket blades from Reliable Aftermarket Parts are engineered to restore cutting performance on walk-behind and zero-turn mowers that accept the 30227-60/30227-60V family of parts. Each blade measures 20.5 inches long with a 5/8" center hole and a rugged 0.2040" thickness to withstand regular lawn-maintenance work. Sold as a pack of three, this set supplies the blade count needed for a standard 60" deck and replaces original part numbers including 30227-60H and A60227-60N.

What exact dimensions and mounting specs does this blade set use?

These blades match factory geometry so they mount without modification on compatible decks. The set is built for common high-lift mowing applications where lift and discharge efficiency matter.

• Overall length: 20-1/2" (20.5")
• Width: 2-1/2"; Thickness: 0.2040"
• Center hole diameter: 5/8" (0.625") to match spindle shafts
• Sold as a 3-blade pack — requires three blades for a 60" cutting deck

Which mower models and OEM part numbers are compatible with these blades?

This replacement set is compatible with Dixie Chopper walk-behind and zero-turn machines that use the XXW series blade geometry and 60" deck configuration. It directly substitutes several OEM references to simplify ordering.

• Fits Dixie Chopper XXW series and compatible Gravely machines
• Replaces part numbers: 30227-60, 30227-60H, 30227-60V, A60227-60N
• Requires two blades for 40" decks, three for 60" decks

How will these high-lift blades affect cutting performance and grass discharge?

High-lift blades generate stronger vertical airflow, which lifts grass blades for a cleaner cut and improves clippings evacuation through the chute. Expect better bagging and a neater finish when blades are sharp and balanced.

• High-lift profile improves clippings lift and evacuation
• Heavy-duty steel resists bending and warping under load
• Consistent thickness helps maintain balance and reduce vibration

What should I check before installing these replacement blades?

Measure your current blade and verify spindle shaft size and hole pattern before purchase. Also inspect spindles and hardware for wear to ensure a safe, secure installation and even cutting.

• Confirm center hole is 5/8" to match your spindle shaft
• Inspect blade mounting hardware and replace worn bolts or washers
• Balance blades after sharpening to prevent vibration

Who is this for: This three-pack of 20.5" high-lift mower blades is intended for owners, service technicians, and landscaping professionals maintaining Dixie Chopper and compatible Gravely mowers with 60" decks. It's a practical choice if you need direct-fit replacements for the 30227-60 series numbers, want improved clippings management, or require a durable aftermarket option for regular turf maintenance. If your mower uses a different hole diameter, length, or deck configuration, measure before ordering to confirm fitment.
