The 8TEN LawnRAZOR 810-CBL2382D is an aftermarket 21.75-inch toothed mower blade for selected Husqvarna and Jonsered machines. It is sold as a direct replacement for OEM part numbers 580244001, 580244002, 532446784, and 586529601.
Our verdict: This blade is worth considering when one of those exact OEM numbers appears in your mower’s parts list and all physical dimensions match your old blade. Fit is the deciding issue. A 22-inch deck label by itself is not enough to confirm compatibility.
Research note: This is a research-based review. I have not personally tested this blade. I checked 8TEN’s current product listing, specifications, replacement numbers, and blade guide on September 5, 2026.

Specifications are from 8TEN’s current listing. Product listings and mower configurations can change, so verify the part number and measurements before ordering.
Will this blade fit your mower?
Start with the OEM blade number in your mower’s illustrated parts list or on the blade you are replacing. The strongest match is one of the four replacement numbers listed above. Then confirm the following:
- Center pattern: a 5-point star, not a round hole, bow-tie hole, or six-point star.
- Length: 21.75 inches, measured diagonally from cutting tip to cutting tip.
- Width: 2 7/16 inches.
- Thickness: 0.125 inch.
- Blade count and orientation: match the parts diagram for your exact model and deck.
Some retailer listings associate this blade with walk-behind models such as the Husqvarna HU550F, HU550FH, HU675FE, HU700F, HU725-series, HU775H, HU800-series, LC356-series, and LB155S. Treat those model lists as a starting point. Model suffixes and production years matter, so the OEM number remains the safer check.
Toothed or mulching blade?
Older marketplace listings sometimes describe the 810-CBL2382D as a mulching blade. The current 8TEN product page identifies both its blade type and lift type as toothed. That naming conflict is a good reason to shop by the exact part number and blade shape rather than by a broad label in a retailer title.
A toothed profile can help recirculate clippings under a compatible deck, but the final result also depends on the mower deck, discharge setup, grass height, moisture, and mowing speed. Do not assume that any blade marketed for mulching will fit or perform correctly on every 22-inch mower.
What stands out
Exact aftermarket replacement numbers
8TEN publishes four OEM replacement numbers and an Oregon cross-reference. That gives buyers more useful fit information than a generic deck-size claim.
Common 5-point-star mounting pattern
The 5-point-star center is used on a number of Husqvarna-family applications. It must match exactly; a similar blade length does not compensate for the wrong mounting pattern.
Clearly published dimensions
The manufacturer lists length, width, thickness, gauge, and material. Compare all of them with the removed blade and your mower documentation before installation.
Limitations to understand
- This is an aftermarket blade rather than a Husqvarna-branded OEM part.
- The phrase “22-inch deck” does not guarantee fit.
- Retailer descriptions disagree on whether to call it toothed or mulching.
- A new blade still requires correct installation and torque according to the mower manual.
- Cut quality cannot be predicted from blade dimensions alone.
Installation and safety checks
Disconnect the spark-plug lead on a gas mower or remove the battery and safety key on an electric mower before working under the deck. Wear cut-resistant gloves and secure the mower according to its manual. Note which side of the old blade faces the deck before removal.
Use the mower manufacturer’s specified fastener, washers, blade orientation, and torque value. Do not guess at torque or reuse damaged mounting hardware. After installation, rotate the blade by hand only while the power source is disconnected to check for interference. If the blade does not seat flat or the center pattern does not engage fully, stop and recheck the part number.
Pros and cons
Pros
- Exact OEM replacement numbers are published.
- Full blade dimensions are available for comparison.
- Current manufacturer listing identifies the design as toothed.
- Oregon 95-615 cross-reference provides another compatibility check.
- Often priced below an OEM-branded replacement.
Cons
- Compatibility requires careful verification.
- Conflicting retailer terminology can confuse buyers.
- Aftermarket fit and finish may be a concern for buyers who prefer OEM parts.
- No responsible review can promise better cut quality without testing it on the exact mower and lawn.
Frequently asked questions
Is 810-CBL2382D a 22-inch blade?
It is intended for selected mowers commonly described as having a 22-inch deck, but the blade itself measures 21.75 inches from tip to tip.
What OEM numbers does it replace?
8TEN currently lists 580244001, 580244002, 532446784, and 586529601.
Is it a mulching blade?
8TEN’s current page calls it a toothed blade. Some older retailer titles call it mulching. Use the 810-CBL2382D part number and the pictured shape to make sure you are looking at the intended product.
Does it fit every Husqvarna 22-inch mower?
No. Match the OEM number, 5-point-star center, dimensions, and exact model parts diagram.
Does a replacement blade arrive ready to install?
New mower blades commonly have a factory edge and protective coating. Follow the blade maker’s and mower maker’s instructions; do not sharpen or alter a new blade unless those instructions call for it.
Final recommendation
Choose the 8TEN 810-CBL2382D when your mower documentation calls for one of its listed OEM replacement numbers and the mounting pattern and dimensions match. Skip it if you are relying only on deck width or a similar-looking product photo. For a safety-critical rotating part, an exact match matters more than a small price difference.
