2 BD18BP Low Lift Mulching Blade Replaces Black & Decker 90548199 Length 17 1/2 in. Width 1-3/4 in. Thickness .150 in. Center Hole 1 in.

The 10 y.o. Multiple time resharpened Blade just ‘wasn’t cutting it’ anymore. Found this on a Google search, found it to match dimensions (length, width, hole size). Two blades came packed well (be careful because they’re very sharp). Took 5 minutes to get old blade off & one of new ones on. New blade is definitely thinner than old but fits fine. Now mowing takes 1/2 the time. I’m very happy.

Yes, it works for the titled mower. Electric 18" lawn hog mulching mower. However, does requires a slight modification. The blades hole is to big for the mower bolt. Go to harbor freight and buy a 12 piece saw adapter set for a few bucks. It's really just 2 washers that go over the bolt making the blade fit. It's really easy. The 2 blades are a great price if your willing to make the one modification.

The blade is not a mulching blade like the one that came with the Black & Decker Electric mower that I have. It fits and seems to be working well.

If you own one of the old Black & Decker electric mowers (model MM675) like I do you probably can NOT find a replacement blade with the correct hole diameter (7/8"). This blade is an almost perfect replacement except for the hole, which is 1" diameter. As is, you CAN'T use this blade on the B&D MM675 mower because it will NOT remain centered when spinning and will become unbalanced. This will make your mower shake tremendously (=dangerous!!!). To prevent this, you need a reducing bushing (basically a metal ring) to FILL the the GAP between the hole and the plastic fan body. I purchased this metal bushing that reduces from 1" to 7/8" diameter: https://www.amazon.com/gp/product/B00004RK8F/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Here is an alternative: https://www.amazon.com/gp/product/B000P4OCK0/ref=ox_sc_saved_title_1?smid=A1WO0LWTFI0BL8&psc=1 Another lesson learned which I will share: When I removed the old blade, I noticed that the blade sits on a round plastic fan. When I removed the plastic fan, I noticed that six of the eight fan blades were missing (broken off). There is actually a warning on the fan body to not operate the mower without the fan...which, in essence, I was doing with all the missing fan blades. A functioning fan probably helps keep the motor cool and also helps keep the cut grass suspended in the air stream for proper mulching (which it was not doing very well for some time). You can buy a replacement fan and here is the one I purchased (but there are other sellers). https://www.amazon.com/gp/product/B010C7AI7A/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 I hate throwing away good equipment if I can fix it and this B&D mower has been awesome. Many thanks to all the suppliers out there who continue to make parts for our old equipment! Good Luck!

Original blade for the B&D LM175 was discontinued, so opted for these - with an added bushing to bring the hole size down to 7/8". Fits just right and tried it out today... cuts great. Made in USA too for added bonus.

About the 1" mounting hole diameter that some find too big for their 7/8" mount. Here's what I did. I went to my local Harbor Freight Tools and purchased item 1444 for $2 (Saw Blade Bushing Set 12 Pc). It's a set of 12 adapters/saw blade bushings but I only needed the 7/8" to 1" adapter (Package contained two adapters for 7/8" to 1"...the rest I threw away). It's basically a metal washer that snugly fits inside the blade's mounting hole to reduce it to 7/8". I taped the extra adapter to the 2nd spare blade you get with this 2 Pack of mower blades for later use if I ever need to use the spare blade. For a total cost of $21, I now have a like new cutting MM675 Lawn Hog purchased in 2006 and a spare blade. I couldn't be more pleased with the blade's performance or the adapter set that allowed me to install said blade. I'd take credit for this solution but if you read through the Q&A attached to this item you'll see this answer provided by "G.A." I can confirm it worked for me.

Correct blade. When broken blade remove it revealed broken mower blade insulator.

Does not fit LM-175. The hole is too big, and the mower becomes severely unbalanced. The seller should stop misleading the consumers!
