The year, make, model and engine info would help.

A light and cordless hedge trimmer would be best for a woman of petite stature. The Earthwise 20-inch cordless hedge trimmer would work great in this situation.
The #1 best selling hedge trimmer available at Home Depot is a Black and Decker 24" Hedge Hog trimmer, model HH2450, for $69.97. If you order online you get free shipping!

40:1 is the correct mixture for the fuel and 2 cycle oil. 3 oz. of 2 cycle oil per gallon of gas. I have Craftsman Line Trimmer 358.795190 (Model #). It has the quick release shaft for other attachments. Hopefully this will help you.
This model # shows as a black&Decker cordless string trimmer.
