RANSOTO 48" Deck Lawn Mower Blades Compatible with John Deere Cut Deck 145 155C D140 E140 LA130 S140 X140 Z245 EZtrak Zero Turn Mower High Lift Replace GX21784 GY20852 AM137757 AM141035 3 pcs

What It Is

This is a 3-pack of high-lift blades designed for 48-inch John Deere mower decks. The aggressive lift profile improves grass clipping discharge and bagging performance, making them ideal for thick or wet grass conditions.

Fitment & Compatibility

• Deck size: 48-inch cut only. Do not use on 42-inch or 54-inch decks.
• Compatible models: John Deere 145, 155C, D140, E140, LA130, S140, X140, Z245, and EZtrak Z245 zero-turn. Also fits select older models with 48" decks.
• OEM cross-reference: Replaces GX21784, GY20852, AM137757, AM141035.
• Measure before buying: Blade length must be 20.5 inches (center hole to tip). Center hole is 15/16" diameter with a 7-point star drive. Check your deck spindle orientation—these are symmetrical and fit standard John Deere mounting.
• Not compatible with Quick-Change (Q/C) spindles or non-John Deere decks.

Key Things to Know

• High-lift = more power draw – Expect slightly higher engine load and reduced runtime on electric mowers. Best for dry grass; wet clippings may stall the deck.
• Installation tip – Torque mounting bolts to 70-90 ft-lbs. Use thread locker if bolts loosen during use. Always replace all three blades at once for balanced cutting.
• Quality notes – RANSOTO blades are heat-treated and powder-coated (rust resistance). They are slightly thinner than OEM, which can reduce durability in rocky terrain.
• Common gotcha – The high lift can cause “scalping” on uneven lawns if deck isn’t level. Set cutting height to at least 2.5 inches for first use.

Should You Buy It

Yes, if you own a 48-inch John Deere lawn tractor or zero-turn and want better bagging or discharge performance than standard blades. The price is roughly half of OEM, and with a 4.6-star rating, most buyers report solid fit and sharpness out of the box. Avoid if you mow rocky/rough ground or need maximum blade life.
