One New Pack of (3) 48" Deck Mower Blade Fits John Deere 48C, Z355E, Z355R, Z525E, Z535M, Z540M

What It Is

This is a set of three 48-inch deck mower blades designed for select John Deere zero-turn and lawn tractors. They are aftermarket replacements for cutting grass on residential or light commercial properties.

Fitment & Compatibility

Before buying, confirm your mower’s deck model is 48C and your machine is one of these: Z355E, Z355R, Z525E, Z535M, Z540M. Measure your existing blade length—it must be exactly 48 inches (blade tip to tip when mounted on the deck). These blades have a center hole diameter of 1 inch and an offset of 0.625 inches. They are not OEM John Deere parts, so double-check that your original blades have the same hole size, thickness (typically 0.25 inches), and air lift design. If your deck uses a different blade length or hole pattern, these will not fit.

Key Things to Know

• Quality: 4.7/5 rating suggests good durability and balance for the price, but aftermarket blades may not hold an edge as long as OEM ones in heavy or wet grass.
• Installation: Easy for DIY with a socket wrench and blade removal tool. Always disconnect the spark plug and wear gloves.
• Torque: Tighten blade bolts to 50–60 ft-lbs—under-tightening can cause blade throw, over-tightening can strip threads.
• Sharpening: These are not reversible—when dull, replace the set. Sharpen only if you have a proper grinder and balancer to avoid vibration.

Should You Buy It

Buy this set if you have one of the listed John Deere models with a 48C deck and want a budget-friendly, high-rated blade set for regular mowing. Skip it if you need OEM parts for warranty reasons or if your deck uses a different blade length or mounting pattern.
