UDC Parts GY20850 Mower Blades for John Deere 42 Inch D105 D130 S100 S110 S240 X300 E100 E110 LA135 Replaces OEM no. AM141033 GX22151 AM131033 AM137333 / Gator Mulching Blades 2 Pack

Item arrived and with out damage, what can I say, they are mower blades

OMG. What a difference these blades make. I have a 17 Y/O 42” riding mower (picture) and put these blades on it. It’s like going from a chainsaw to mowing with a Rolls. YES, it is that dramatic. I started the mower after changing the blades and immediately noticed the sound difference. I engaged the belt, mowed a few feet and thought the belt had not engaged the blades. So I disengaged, backed up and noticed that the lawn was perfectly cut. I engaged the blades again and listed carefully to the smooth sound coming from the blades. It was a very soft hum. Like a low whisper. The before and after difference is astonishing. The mulching action with these blades completely disintegrate the grass clipping. Forget bagging or re mowing to get rid of the clipping-pile rows. There are no clippings left! Seriously, these Gator style blades work crazy amazing. They fit my 42” deck perfectly, are extremely quiet, ( Hum rather that a roar) lift the grass almos like a vacuum. I will never use another blade again. A couple of caveats, they suck like you are mowing with a vacuum. A sort of “Flowbee” for the lawn. For that reason. Do not run over any objects, like a garden hose because it will destroy it. The second one is it will suck sand/dirt if you run over some. Yes, I recommend them, will buy them again, and would give them as a gift. Absolutely amazing blades! Great product, price, quality, performance, and function at an extremely low noise level. Get them! lol

good quality product, quick and easy purchase and delivery.

I suppose most importantly is that they work great! I replaced my old blades (and they weren't that old or dull) with these and I was impressed with how much better they cut & mulched the grass. I was able to drop my deck one additional notch with great results. Next I have to say how impressed I am with their customer service. I've seen a 50/50 split on internet blogs about using this type of blade with a mulch kit. I thought the best thing to do was go to the manufacturer for advice. I contacted the 3 most know suppliers with my questions, twice , and didn't get a single reply. So when I sent the same question to UDC Parts, I received an answer within 12 hours easily. Then I had a different question about something else and AGAIN, UDC responded QUICKLY. The quality of these blades is outstanding. You know it's a "guy thing" where when you buy tools and accessories you come to realize what quality is. To top things off, their prices are very reasonable especially considering all the other pluses. I will always be a loyal UDC custom for my future needs!

I’m very happy with the UDC Parts 532138971 / 138971 42-inch mower blades. They were an exact fit for my 42-inch deck and installed quickly without any modifications. The blades came well-packaged and felt sturdy right out of the box. After installing them, I noticed an immediate improvement in cut quality. The grass is cut cleanly and evenly, with no tearing or missed spots. They handle both regular mowing and slightly overgrown grass without bogging down the mower. The balance seems good too—no excessive vibration during operation. Durability has been solid so far. After several months of mowing, the blades are still holding their edge well with minimal wear. For the price, these are an excellent replacement option compared to OEM blades. Overall, these mower blades deliver great performance, fit perfectly, and offer excellent value. I would definitely purchase them again and recommend them to anyone needing reliable 42-inch mower blades.
