How Do You Use Your Electric Lawn Mower?

We have received a power mower as a gift (it is a hand mower), my husband has used it for several months. The only way he can use it without cutting the power cord is pushing and pulling the mower with one hand while pulling, pushing, to choose the cord with the other. I think we should double the time to mow the lawn with this machine. . . . is there a trick you can give us? perhaps something that we do not know, like a retractable cord. . . I do not know. . . . something you can use to be able to push the machine with both hands
