3 OEM Oregon Gator G5 Mower Blades for 48" John Deere D140 D150 D160 592-616

What It Is

This listing is for three OEM Oregon Gator G5 mower blades (model 592-616) designed for 48-inch John Deere lawn tractors, specifically the D140, D150, and D160 series. These blades are for mulching, bagging, or side-discharge mowing on residential lawns.

Fitment & Compatibility

Before buying, verify your mower deck is exactly 48 inches (not 42 or 54). These blades fit John Deere D140, D150, and D160 models with a 48-inch stamped deck. The OEM part number is 592-616; cross-reference with your current blade’s part number (often stamped on the blade). Measure your existing blade length (18.5 inches), width (2.5 inches), center hole diameter (1 inch), and offset (0.5 inch). These are aftermarket replacements, not John Deere OEM, but Oregon is a reputable brand. They will not fit 42-inch or 54-inch decks, nor older models like the D130 or D170 without checking deck size first.

Key Things to Know

• Quality: Oregon Gator G5 blades use hardened steel with a serrated edge for better mulching and lift. They are thicker than most budget blades and hold an edge longer.
• Installation difficulty: Easy—requires a socket wrench and a block of wood to lock the blade. Torque bolts to 40-50 ft-lbs. No special tools needed.
• Common gotchas: The blades are sold as a set of three; you must replace all at once for balance. Check your old blade’s offset—if it’s different, you’ll get poor cut or vibration. Also, confirm your deck uses a single-bolt blade mount (most D140/D150/D160 do).
• Performance: Best for mulching leaves and grass; the serrated edge reduces clumping. Not ideal for very thick or wet grass—go with a high-lift blade for that.

Should You Buy It

If you own a 48-inch John Deere D140, D150, or D160 and want a durable, aftermarket blade that mulches well and lasts longer than cheap options, this is a solid buy at $62. The 4.8-star rating from six reviews suggests it works as advertised, but double-check your deck size and blade measurements before ordering.
