I got the mm575 lawn mower as a gift without the power cord. Where do I buy a replacement b&d-manufactured or generic power cord? thanks. Victoria

You should be able to buy a good quality cord at your local hardware and be on your way

You should be able to use any decent (i.e. thick) outdoor power cord. The trick with the disconnecting problem is that there is a nobby bit on the switch housing that you are supposed to loop the cord around. The cord plugs into the bottom of the switch housing and then you are supposed to push a loop of the cord up and over the tab on the outside of the handle.
