Perfect fit.
Perfect fit. Just started using them, so not sure how long they will last, but they make a clean cut and do the work for my five acres of grass. I do recommend.

Awesome cut...even in thick wet grass!! NO CLUMPING!! BUY THEM!!!
These blades are awesome! Over the years I've tried all of the fancy Laser Edge, Oregon Mulching, Tri-Cut, Super Touch, Tri-Fecta, does everything...will cook you dinner type blades on my ZTR mower :) I'm not sure what makes these things different....but man, they cut awesome! I tried them out on a thick lawn that was wet from dew, and a few days past when I should have mowed it. The first thing I noticed was how smooth they were...no vibration at all (I usually check the balance on new blades before I install them...but these I didn't)......and they cut awesome! Not sure why the design is differnet from the other high end blades, but these things don't clump up at all....they blow out a fine mist of grass...no climbing, no chunks, nothing...even on thick wet grass. Super impressed with these blades so far. Not sure what the "magic sauce" is on them...the look pretty plain, but they sure cut awesome! I couldn't be happier with them!! These will be my go-to blades in the future!!! Not very expensive, and so far them cut better than any other blades I've tried over the years. They are awesome!!

Fit perfectly on my John Deere E130
Love these blades. I put a fresh pair on every year and have the old ones sharpened. After doing it a few times I can get both blades replaced and the deck hooked back up in about an hour with minimal deposits into the swear jar. They cut and mulch great. Great value. Hefty blades, feel very solid.

Double check fit! Great blades so far.
Precision fit, high quality appearance and green powder coat. Came with. Thread lube . Sharp edges. These fit tight. Clean the decks inner edges-sides., hub/spindle, bearing, and mount pattern (5Star). Install one blade and carefully spin it several times, checking clearance. Clear enough tolerance so a bent deck edge on uneven rough ground doesn't catch a blade edge. Repeat for 2nd blade. I've only got about 2 acres cut on the new blades so a later review of quality, keeping a sharp edge, ease of sharpening and durability of powder coating may follow ๐ Great value, so far, perfect!

Not a perfect fit for Bad Boy Magnum
These appear to be well-made blades. I was impressed that a mower deck scraper and thread grease was included! However one of the blades I received was slightly out of spec. The hole was a little large and appears slightly off center. One end of the blade stuck the edge of the mower deck repeatedly when I turned the the blades to test them. I grinded down the edge of one side to get the balance correct and everything appears to be okay now. My purchase was for a Bad Boy Magnum 54" with round holes.

Great product
I recently purchased powder-coated mulcher lawn mower blades for my 22" front wheel drive Toro push mower. These blades are designed with a non-stick surface that minimizes grass buildup, resulting in cleaner cuts and less frequent maintenance. The coating not only enhances durability but also provides resistance to corrosion, which can significantly extend the lifespan of the blades. Here are some key benefits of using powder-coated mulcher lawn mower blades: **Enhanced Durability** - **Corrosion Resistance:** The protective layer from the powder coating helps prevent rust and corrosion, allowing the blades to last longer. - **Durability:** The coating strengthens the blades, making them more resilient to wear and tear. **Improved Performance** - **Non-Stick Surface:** This finish reduces grass accumulation on the blades, leading to cleaner cuts and minimizing clogs during operation. - **Less Maintenance:** With less grass buildup, you'll enjoy fewer cleanup interruptions, resulting in more efficient mowing sessions. **Overall Advantages** - **Corrosion Resistance**: Extends blade lifespan - **Non-Stick Surface**: Reduces grass buildup - **Enhanced Durability**: More resilient to wear and tear - **Less Frequent Maintenance**: Increases mowing efficiency

These blades get the job done
Easy to install and really do a great job mulching. They have a longer cutting edge than other blades Iโve used. I would recommend these blades. And for the price why would you resharpen. Just buy new.

Great replacement mower blades- best I have ever had!
I have had to replace my mower blades for the Husqvana YTH18542 often. They have always seemed very thin and wear out quickly on my sandy lawns. I tried these blades because they just looke a lot thicker and boy was I right. They are probably twice as thick and much more substantial. The packaging was surprisingly great given the price of them. Each one came in it's own sleve complete with rubber tips covering the sharpened corner. Also included was a packet of rust inhibitor for the bolts and a small putty type scraper/knife for cleaning up the area before attaching the blade. After replacing the blades the mower was much more quite and vibration free giving a good stable ride. They were sharp enough to move cleanly and are heavy enough I can sharpen a couple times as needed(which I never could with the original blades).

WOW Blades
I bought these for my John Deere S130 mower. They were cheaper than the Deere OEM blades and seemed to have VG reviews with some reviewers noting how well they cut, so what the heck. At first glance they didn't appear the same quality as they were thinner and lighter than the Deere blades, but then I cut grass with them. The design is different than the OEM. I think it might be those rakes on the back edge, but they made a far superior job on my lawn. They did a much better job of distributing the clippings with fewer clumps. I waited until I had 3 cuts before leaving this review. My third cut I was away for a full week and the grass was long. The grass was wet, but I had to cut it as I was leaving again for another week. They still did a great job on heavy wet grass. I would buy these again.
