What It Is

This is a set of two aftermarket mower blades designed for 38-inch cutting decks, primarily used on older John Deere lawn tractors and garden tractors. They replace worn OEM blades to restore clean, even cuts on residential and light commercial properties.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 38 inches (not 42 or 48). These blades fit John Deere models: 316, 318, 322, 325, 111, 116, 160, 165, GT235, GT242, LT133, LX176, LX178, LX188, S92, SRX95, STX38, and SX95. They replace OEM part numbers AM100946 and M82408. Measure your existing blade length (should be ~18.5–19 inches), center hole diameter (likely 7/8-inch), and blade thickness (about 0.203 inch) to verify match. Cross-check your model year and deck serial number if possible, as some older decks may vary slightly.

Key Things to Know

• Quality: OCPTY blades are heat-treated and coated for rust resistance, but they are aftermarket steel, not OEM hardened alloy. Expect adequate durability for regular residential use, but they may dull faster than John Deere factory blades under heavy or rocky conditions.
• Installation: Straightforward swap if you have a socket set and jack. Use a blade removal tool or block of wood to prevent spinning. Torque bolts to 30–40 ft-lbs. Always check blade balance after installing; these may need minor filing to balance perfectly.
• Common Gotchas: The 38-inch deck uses two blades, not three. Do not mix with other lengths or brands on the same spindle. If your deck has a stamped or welded underside, verify blade tip clearance (minimum 1/4 inch from deck shell). Old blades may have worn spindles—inspect bearings while you’re under there.
• Price vs. OEM: At $25.99 for a two-pack, these are about half the cost of OEM equivalents. The trade-off is potentially shorter lifespan, but for seasonal mowing on turf, they perform well.

Should You Buy It

If you own one of the listed John Deere models with a 38-inch deck and want a cost-effective blade replacement for routine mowing on standard grass, this is a solid choice. Skip it if you need maximum longevity for commercial use or often cut in sandy/abrasive conditions—OEM blades will last longer. For homeowners, the price and positive reviews make it a reliable budget option.
