Maxpower 3-Blade Replacement Set for 54-Inch John Deere Rider — Precision-Sharpened, Powder-Coated

Maxpower 561813B is a three-blade replacement set made in the USA for 54-inch John Deere G110-series riders that replaces OEM GX21380, GY20679, and GY20684.

If your 54-inch John Deere rider's cutting performance has faded, the Maxpower 561813B three-blade kit offers a direct-fit, factory-style replacement built to meet or exceed OEM specifications. Each blade is 18-5/8 inches long, 2-3/4 inches wide, and uses the 7-point star center hole pattern common to many John Deere decks. The blades arrive precision-sharpened and powder-coated for corrosion protection; the coating wears off on the first cut to reveal a sharp, ready-to-use edge.

Will these blades fit my 54-inch John Deere mower?

These blades are designed for 54-inch mower decks that accept the 7-point star center hole and match the listed OEM numbers. Fit depends on the exact deck model and the blade OEM number stamped on your current blades.
