SOURCE: BLack and decker electric lawn mower blaDE IS loose and not turn

If it's like mine (MM 875), it has a plastic "clutch" that has little edges on it that broke off when I was chopping sticks with the mower ;-) Went to the local B&D place and got a new one for less than $3.

But now I'm worrying about the nut holding the blade on -- if I try to get it good and tight, the plastic "clutch" spins around off-kilter... Funny how I never even looked at the blade after I bought the mower used, but never worried about the blade being loose and flying off.

It sounds like bearings are seized and need to be replaced. Too much attempted use will burn out the field windings and a rewind or new motor will be needed - both costly.

Why is my electric Black and Decker lawn mower still vibrating and loud after I replaced the blade insulator and fan?


disconnect all power and turn the mower on the side
turn the cutter blade /base by hand and watch the centre bolt or shaft
if it moves in a bit of a circle then it indicates that the motor shaft may be bent, causing the vibration at speed

How do you check to see if Drive pulley bearings are bad


take belt off, grab blade at end and watch center bolt move more than a little bit or swing by itself when turned loose. Try turn blade with hand to feel bearing roughest is another way

Lawn mower ran out of oil and stopped running put new oil in and still not running is there something to do after putting oil in to make it run


If you can turn blade by hand first removing spark plug you then can try squirting 30w oil into plug hole and turn blade by hand. replace plug and try to start. Depending on whether you gouged the cylinder it may start.

Lawnmower blade wont turn


Probably bent the shaft. Disconnect the spark plug to prevent accidental starting and lay the lawn mower on its side. Slowly turn the blade with your hand and watch the center of the shaft. If it wobbles at all it is bent. $150 to $200 job. Probably time for a new mower.

My electric lawnmower sometimes does not start, just humms. Then I TURN IT OVER, AND TURN THE BLADE A LITTLE BIT. the blade feels hard at first but soon feels loose. then it wil start as normal


The lawnmowers electric motor has a bad spot on the armature. You need to replace the electrical brushes that contact the motor. If you are lucky you may just need to clean them and reinsert them in to brush holders.

The pull start cord will only move about 3-4 inches and then it stops and then cord stops, Troy built- Briggs/Statton 21 inch self-propel lawnmower.


The mower's drive shaft may need to be lubricated. If you turn the mower over and try to move the blade by hand (with the mower off, of course) does it move, or is it hard to move? If it's hard to move or it won't move at all, lubricate the shaft by squirting some WD-40, 3-In-1, or other lubricating oil onto the drive shaft where it meets the chassis of the mower. Squirt enough oil to cover the circumference of the drive shaft, then try to spin the blade again. It should at least spin a little bit now. Squirt some more oil and spin the blade again, until the blade spins easily. Then turn the mower back over and try to pull the start cord -- it should pull normally now.

I changed the blade, and now it won't start!


Did you replace the blade with a heavier blade, or an identical one? If the pull cord won't pull, it's usually either the blade or the blade shaft causing the problem. Try oiling the shaft and making sure nothing is obstructing the blade from turning.

If you have a pair of heavy gloves, try turning the blade by hand and see if it moves. Squirt some oil onto the shaft where it meets the mower and try turning it again.

Will not turn over. Installed new battery. Still


Hmm.. Could be that the motor is a bit stuck on the top of the compression stroke..

With everything turned off - turn the motor over a few time by hand - by turning the blade..
Then try starting it..

OR starter could be a bit stuck - try this.. While the key is turned like you are trying to start it - give the starter a little smack with a small hammer..

Hope this helps !!
Please rate me good ;o)

Lawn mower died. Pull rope locked up


remove the spark plug and try to pull the rope. Sometimes the coil can get loose and wedge against the flywheel. if that's not the problem then pour a little oile in the spark plug hole, let it set a bit, if it still won't turn over then you have an internal engine problems. Not very common but it can happen
