    • Double check fit! Great blades so far.
Size: 22-7/8" - 5 pt star
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 😉 Great value, so far, perfect! ... show more

    • Awesome cut...even in thick wet grass!! NO CLUMPING!! BUY THEM!!!
Size: 18" - Round (5/8")
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!! ... show more

Excellent blades. Even came with a scraper and anti rust lubricant for the bolts. Easy to install and as heavy duty as the ones that I replaced. Very happy and I would recommend.

    • These blades get the job done
Size: 23-1/4" - 6 pt star (2-1/2")
Easy to install and really do a great job mulching. They have a longer cutting edge than other blades I’ve used. I would recommend these blades. And for the price why would you resharpen. Just buy new.

    • Not a perfect fit for Bad Boy Magnum
Size: 18-3/4" - Round (5/8")
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. ... show more

    • UDC Blades for Cub Cadet i1046 - Remarkable Value!
Size: 16-1/4" - 6 pt star
This is the second set of UDC blade kit for my Cub Cadet i1046. I bought the first one two years ago and it served me well, even with a degraded deck drive system with 18-years of hard service. I decided to replace all three spindles, the two idler pulleys, the tractor's PTO and installed a new deck belt from UDC as well. Upon completing these updates, I tested the tractor's performance by mowing 2 acres of overgrown grass. Minus a few portions of the lawn that were extremely grown, the tractor had no issues with properly mowing this space. The blades mulched the overgrown grass quite well and aided the tractor by preventing it from becoming bogged down. Another big plus is that even though the older UDC blades were devoid of nicks or gouges, the affordability of these ones made the decision to replace them instead much easier. OEM MTD/Cub Cadet blades are over twice the price without giving you extra performance or durability. I will take the time to resharpen the original UDC blades to have them ready for next mowing season. I would recommend these blades in a heartbeat! ... show more

    • Fits 42” YT3000 deck
Size: 21" - 5 pt star
Mulching blades work very well on my YT3000. Minimal clumping even in grass that I should have cut 3 days prior, before it rained. Blades are as sharp as they should be, leaving a clean and even cut. Kit came with a small gift of anti seize compound for the blade bolt threads. Will purchase again.
