We upgraded to a cordless electric mower and have a 3-year old electric Greenworks mower for sale. It is very powerful and I have cut grass close to 10" tall comfortably. Our yard has more flower beds and trees now, so maneuvering the cord has become challenging. If you have a yard that is relatively free of obstacles, this mower is a great fit. Much better than gas power with changing oil and spark plugs, running for gas when it's empty, and breathing noxious fumes.
This model sells for over $200 new and we are selling ours for $90. Included at no extra charge is a 100 foot heavy duty extension cord.
