GY20850 John Deere 42 Inch Mower Blades Replace D105 D130 D110 S100 GX22151 E130 Z225 E120 D100 D125 E110 LA125 LA115 LA105 AM141033 Lawn Tractor Riding Mower/Gator Mulching / 2 Pack

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

Arrived on time and as described. Perfect fit for my 46” husqvarna mower. Well made with plenty of lift for mulching. Cut an acre of leaves quickly turning them into ash. Sure it will do as well on the grass this season.

These blades are direct OEM replacements. If not better than OEM. They feel slightly heavier than stock blades and mount just as easy to the mower. These were much cheaper than the big box store blades and perform well.

These are the best Mulching blades I have ever used. These turned leaves and small twigs to dust. The normal blades I have used just chop and leave me running multi times over the same area. These were a one and done. I was very happy with them. Will buy again.

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.

Best Blade on the market, And no, I don't get mine free! I have tried them all, I have a sandy soil lawn, leaves twigs, and small branches have not destroyed them, I am very satisfied with the Quality of the cut, even when they start to get dull they out cut most other brands. Not to mention, I own a TORO which is the Mercedes of them all! And yes, I'm still making payments on that Baby!
