Swisher 4855 Replacement 15.5 in. Blade for Select 44 in Rough Cut Mowers

What It Is

The Swisher 4855 is a replacement 15.5-inch blade designed for select 44-inch Swisher Rough Cut mowers, used for heavy-duty brush and tall grass cutting. It fits Swisher models L4054, L44-130HS, L44-130HSB, L44-130ES, and L44-130ESB.

Fitment & Compatibility

• Deck size: Only for 44-inch cutting decks. Will not fit 36-inch or 50-inch Swisher decks.
• Model check: Confirmed compatible with Swisher L4054, L44-130HS, L44-130HSB, L44-130ES, L44-130ESB. Verify your model number on the mower’s ID tag (usually under the seat or on the frame).
• OEM vs aftermarket: This is an OEM Swisher replacement, not a universal blade. Avoid generic “fits Swisher” blades without exact measurements.
• Measurement: Blade length is 15.5 inches center-to-center (mounting holes to blade tip). Center hole diameter is 5/8 inch. Measure your old blade to confirm.
• Blade type: Single-edge, not reversible. Ensure you have the correct spindle orientation (left-hand or right-hand rotation) for your model.

Key Things to Know

• Quality: Made from heat-treated, hardened steel for durability in rough cutting conditions (saplings, thick weeds). Holds edge longer than standard mower blades.
• Installation: Moderate difficulty. Requires a torque wrench (specs: 70–90 ft-lbs) and a blade removal tool or block of wood to prevent spinning. Wear gloves.
• Common gotcha: Do not overtighten—this can warp the blade or strip the spindle. Replace the blade bolt and washer if they show wear.
• Sharpening: Can be sharpened 1–2 times before replacement is needed. Maintain a 30-degree angle and balance the blade after sharpening.

Should You Buy It

If you own one of the listed Swisher 44-inch Rough Cut models and need a direct OEM replacement for heavy brush or tall grass, this blade is the correct fit. It’s overkill for standard lawn mowing but ideal for rough terrain. Avoid if you have a different Swisher model or a non-Swisher 44-inch deck—measure first.
