Description

Built for compatible 54-inch mower decks, M143520 Medium Lift blades provide dependable cutting performance for select John Deere mowers. Replacing OEM part number M143520, this 3-blade set supports clean, consistent mowing across listed applications.

Made from premium, high-strength steel, the blades are designed to keep the cutting edge stable and deliver long-lasting performance under demanding conditions. Each blade is pre-sharpened, marked with safety paint that wears off in the first use, and its cutting edge can be safely sharpened again when it gets dull. Below you will see all compatible lawn mower models.

Ideal for routine blade replacement, this Medium Lift set helps restore reliable cutting when existing blades become worn or damaged. The Circle (13/16") center hole matches the specified mounting configuration for compatible 54-inch decks. Please be sure to check your mower model number, deck size and original OEM blade number before ordering.

If you are unsure about compatibility, compare your original blade number or mower model before ordering.

FAQ

Does this Medium Lift blade set replace more than one OEM part number?

Yes. This set replaces OEM part numbers M143520, UC22010, and UC40844. Compare your original blade number before ordering to confirm compatibility.

Is UC22010 included in this replacement blade set?

Yes. OEM UC22010 is listed as the second replacement part number for this 3-blade Medium Lift set.

Are these mower blades replacements for OEM UC40844?

Yes. OEM UC40844 is listed in the Replaces OEM Part Numbers list. Please verify your mower model and 54-inch deck specifications before ordering.

How often should I sharpen lawn mower blades?

Resharpen the blades whenever the cutting edge becomes dull. These blades can be safely resharpened as needed to help maintain consistent cutting performance.

Are these mower blades already sharpened?

Yes. The blades are pre-sharpened and painted with a safety paint that wears off on first use.

Why might my mower start cutting less evenly?

A dull or worn cutting edge can reduce cutting consistency over time. Inspect the blades when mowing performance begins to decline.

Should I sharpen new mower blades before using them?

No. These blades are already pre-sharpened, so additional sharpening is not required before initial use. The protective safety paint will wear off naturally during operation.
