Electric Mower On A Steep Incline?

I have a back yard with a strong inclination, probably around 30 degrees. Eclectic power mower is very heavy to handle, may be tip top heavy side and when you cannot go to make up the hill. Besides push reel mower does not work very well either. I will try a power mower. Will this work? I can not afford to have a company to come mow my lawn. Any suggestions other than to let die and make my life easier? Thank you
