ILONPA 54" Medium-Lift Mower Blades for John Deere & Craftsman 7-Point Star Center, 3-Blade Set, Rust-Resistant Painted Edges

ILONPA 54" medium-lift replacement mower blades are a three-blade set designed to fit 54-inch decks with a 7-point star center, replacing OEM GX21380, GY20679, GY20684, GY20686, SPM684375001 and compatible John Deere/Craftsman models.

These blades are engineered for homeowners and landscapers who need a direct-fit replacement for popular 54" lawn mower decks. Each blade measures 18 5/8" long, 2 2/3" wide and 0.197" thick with a 7-point star center hole, ensuring compatibility with models such as John Deere D170, G110, 190C, LA150 and several Craftsman decks. The cutting edges are delivered with a protective paint to reduce rust and protect installers; the paint wears off quickly once mowing begins.

How do these medium-lift blades affect cut quality and clippings?

Medium-lift blades balance suction and airflow to lift grass for a clean, even cut without excessive thatch pickup. They work well for general mowing conditions where you want tidy clippings and improved discharge or mulching performance compared with low-lift blades.

• Improves grass lift for uniform cutting height
• Reduces shredding and uneven strips
• Optimizes airflow for side discharge or mulching decks

What should I know about the painted cutting edge and installation safety?

The cutting edges arrive painted to prevent corrosion and to provide a safety coating during handling and installation. That paint is not a wear-coating; it will abrade off quickly during normal mowing and does not affect blade performance.

• Paint protects edges from rust in storage
• Paint reduces risk of installer cuts—wear gloves
• Expect initial light residue to wear off after first uses

How do I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect spark plug, tilt mower for access, remove blades and replace with correct orientation and torque on the fasteners. Routine maintenance includes checking blade balance, sharpening if needed and inspecting for damage.

• Always disconnect spark plug before working
• Torque bolts to manufacturer specs to avoid loosening
• Sharpen when edges dull; replace if bent or cracked
• Check balance after sharpening to avoid vibration
