If I can offer advice, suggest you consider the following :-
If the lawns are smallish, flat and easy to get to with electric power, go for either a Hover (Flymo) with or without collection, suggest 12"/30cm.
These are easy to push as on cushion of air. Alternatively, go for a small lightweight plastic mower with large wheels - again with or without collection Bag/Box.
If power supply a problem or unhappy with cable, look at cordless/battery operated options.
Lastly look for a very lightweight hand mower, there are good Swedish models which are very easy to push especially on flat surface and give a good finish.
Happy mowing !
