This shunted brush is a carbon motor brush with a shunt wire. It is sold separately, however your lawnmower will have two of these, so you should consider replacing both at the same time. These two shunted carbon brushes are attached to the motor. They are in continuous contact with the spinning commutator, so they tend to wear over the use of your equipment. Replacing these brushes should be part of your regular maintenance. When the brushes are worn, this can stop the motor from being able to turn on or only turn on occasionally. A malfunctioning armature can act much the same way, so it is important to inspect it as well.

I bought a brand new Black & Decker electric mower (MM850) 24 years ago. It is an incredible and reliable tool. I really like this mower.
Recently I have an issue with the mower. During cutting, the machine is on and off. I did continuity check of the electric cord. The result is good. The switch on the handle of mower seems working. Please advice which parts I should check? (Some video suggests there might be issue with brushes. How to know that?)
Greatly appreciate your expertise and help.
