POSEAGLE 2-Pack GX20249 42-inch Mower Blades for John Deere — Pre-sharpened Steel with Mounting Hardware

These POSEAGLE two-pack GX20249 mower blades replace John Deere 42-inch blades to restore cutting performance with pre-sharpened, durable steel and included mounting hardware.

If your John Deere lawn tractor is leaving uneven cuts, ragged edges, or slow mulching, fresh blades are often the simplest fix. The POSEAGLE GX20249 twin set is engineered to match OEM fitments for many 42" John Deere decks and related models, offering precise dimensions, a balanced profile, and the bolts and nuts needed for straightforward installation.

Will these blades fit my John Deere 42-inch deck?

Yes — the POSEAGLE GX20249 blades are manufactured to the same key dimensions and hole pattern used by common John Deere 42" mower blades. They directly replace multiple OEM numbers so compatibility covers many models and lawn tractor families.

• Direct replacements for John Deere GX20249, GY20567, GX20433, 330-615
• Also fits many L100/L110 and branded equivalents listed in product details
• 21-3/8" diagonal length, 2-7/16" width, 11/16" center hole, 0.17" thickness

How do these blades perform while cutting and mulching?

The blades use an angled cutting profile and a 1" air lift design that generates strong airflow to lift grass upright for an even trim. They are pre-sharpened and heat-treated to maintain edge retention and balance, helping produce consistent clippings and improved bagging or mulching action.

• Angled edge promotes efficient grass lift and cleaner cuts
• 1" air-lift helps move clippings into the bag or mulcher
• Pre-sharpened finish reduces break-in time for immediate performance

What materials and hardware are included with the blades?

POSEAGLE blades are stamped from medium-strength steel chosen for a balance of toughness and flexibility to resist bending under normal use. The package supplies the correct mounting bolts and nuts so you can replace both blades without hunting down fasteners.

• Medium-strength steel construction for durability and toughness
• Includes 4 x 19M7786 blade bolts (M10x30) and 4 x M85516 blade nuts (M10)
• Coated for transport; protective finish wears off during initial use

How easy is installation and maintenance?

Installation is designed to be user-friendly: blades arrive pre-sharpened and balanced, and the included fasteners match the standard John Deere pattern. Routine sharpening or inspection keeps cutting performance high and helps extend blade life.

• Pre-sharpened blades require minimal initial tuning
• Balanced and hardness-tested to reduce vibration and wear
• Simple bolt-on replacement using common hand tools

Who is this for: The POSEAGLE GX20249 two-pack is ideal for homeowners, landscapers, and maintenance crews who own John Deere 42" deck tractors or compatible machines and need a reliable, ready-to-install replacement. Choose this set if you want factory-style fit, included hardware, and a pre-sharpened blade that restores even cutting and better mulching without sourcing separate bolts or specialty parts.
