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.

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!

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.
