I was on the web looking for some help with my lawn mower and registered on your site. Now that I am here I realize that this is not a site for homeowners with perplexing lawnmower problems. If you could spare a moment to help me I would be very grateful.
I have a Black & Decker Lawn Hog MM 875 (19" electric). The problem I am having is with the blade slipping on the shaft. I can't figure out how to hold the shaft to keep it from turning while I tighten the nut. I can block the blade from turning by using a 2 X4 but the shaft and the nut turn together. Any suggestions on how to do this would be most appreciated. Thanks!

Hi, Essie!

Welcome to MLMF

I do NOT know very much about electric mowers other than how well they do for maintaining smaller lots and yards. I believe I understand the problem you're having and it may be something as simple as finding a flat spot for the cap screw to tighten against. I can't confirm this but I did look around for online help.

Perhaps this may lead to someone (like talking to a real person) from this LINK: Black & Decker Tools | 19" Electric LAWNHOG. If you scroll down the site they do offer How To videos and maybe even email help....

Let us know if it doesn't and we'll try something else...

I don't know if this is the same as yours, but I looked up the manual for a model MM875 on Black and Decker's site, and it looks like there is an elongated hole in the parts called an insulator and spacer that should engage oblong shoulders on the shaft from the motor to keep things from turning. The instructions say to be sure to align the flats in those parts with the flats on the shaft, turning them as necessary, then tighten. Hope that helps.

Don't worry Essie, you're in the right place.
Just take your time and read the manual.
