Question about Black & Decker Garden

Open Question

My Black & Decker MM850 4 HP motor Lawn Mower seems to have gone up in smoke. There was a clear odor of burning insulation after which the motor stopped and would not restart. How do I find a repair facility or at least a full motor (not just the armature) and fix this plus any associated motor failure problems? How long might this take to complete and what is the quoted price of this repair? Additionally is there a repair facility near me where I could just drop off the mower and pick it up later when repaired?

SOURCE: Black&Decker MM675 lawn mower height lever would not stay

I would look in my owners manual and get the part number for the height lever and order a new one. You could also try and wire the height lever so it can not move. I am not sure how it engages but you could may be try and bend the lever so it is tight and won't move. Just a couple of ideas.

Good luck

SOURCE: Murray 4.5 hp Q lawn mower runs rough and smokes.

White smoke indicates that it is burning oil. The smoke would be black if it was running rich. So probably the rings will need to be replaced eventually. These mowers are prone to problems but the carbie is least likely to be the problem. So before you adjust the carbie take the cover off the top and give it a good clean and check that all the hoses are connected and are not cracked. Then make sure the airfilter is clean, blow it out with an air compessor or better still get a new one. Then try it out agian. If this doesn't help there is two screws on the carby marked L and H. Turn these only 1/8th of a turn at a time and note or make their current position. Start with the H scew with the mower at full revs. Turn anti clockwise untill you get max revs then turn it back a bit. Running too lean will over heat the motor and damage it. Then if needed adjust the L (or Low)screw. If you get black or grey smoke when you push the throttle up from idle to full its too rich so turn clockwise. If if slows before it picks up to full revs turn anti clockwise.

SOURCE: I have a problem with a Black and Decker electric

Hello blumph,

I can think of only one or two things that are causing your problems. It could either be approx. a $14.00 switch in the handle that has shorted out, or 2 bad brushes $1.75/ea.on the armature (motor). Both are fairly simple fixes with just a screwdriver and maybe pliers. You might also check and see if the power cord has been chafed or damaged and is shorting out. 

See below for parts:

Something has the motor unable to turn. Do not turn on till you locate the source of the problem lest you burn it out.

My MM1800 started to smoke?


Return it to the retailer for service. it presumably has a warranty that the supplier is obliged to honour. As long as they do not argue that you were somehow not using the device in the manner it was intended you should have no problems. The retailer should, in any case, contact the manufacturer for authorisation to repair or replace.

Sorry i think this thing is toast, if the insulation is gone it will fail a flash test, the outer case could become live and will shock you as there is no earth in the cable.
