Stens Hi-Lift Blade 330-728 Compatible with John Deere X300 Series Requires 2 for 42" Deck AM137327, AM141032, M154061, Black

What It Is

The Stens Hi-Lift Blade 330-728 is a replacement blade designed to improve grass discharge and bagging performance on John Deere X300 series tractors with 42-inch cutting decks. It’s ideal for users who need a durable, aftermarket option for high-lift cutting in thick or wet grass.

Fitment & Compatibility

Before buying, confirm your deck is 42 inches wide and that you need two blades (this part is sold individually). This blade replaces OEM John Deere part numbers AM137327, AM141032, and M154061. It fits John Deere X300, X304, X320, X324, X340, X360, and similar models with a 42-inch deck. Measure your existing blade: length should be 21 inches, center hole diameter 7/16 inch, and thickness 0.204 inch. Check your spindle pattern—this blade uses a single center hole with a 1-inch diameter center hole (not oval or star). Verify your deck’s blade orientation (sharp edge leading) and that the blade’s lift height matches your discharge chute and bagger setup.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand; blades are heat-treated and coated for rust resistance, but may not match OEM sharpness out of the box. Expect to sharpen before first use for best cut.
• Installation: Simple—remove old blade with a socket wrench, install new one with the lift wing facing up toward the deck. Torque bolt to 70-90 ft-lbs. No special tools needed, but a blade removal tool helps.
• Gotchas: Two blades are required for a 42-inch deck—don’t buy just one. Hi-lift blades create more suction, which can overload a bagger if grass is wet or tall; avoid overfilling. Check deck spindle bearings for wear before installing new blades.
• Performance: Improved bagging and side discharge vs. standard blades, but may increase engine load slightly. Not recommended for mulching—use a dedicated mulching blade for that.

Should You Buy It

Buy this Stens blade if you need a cost-effective replacement for a John Deere 42-inch deck and want better grass lift for bagging or side discharge, especially in dense or damp conditions. It’s a solid aftermarket option for DIY owners who don’t mind occasional sharpening and want to save over OEM prices. Skip it if you require mulching performance or prefer zero-maintenance blades.
