I'm getting too old to pull-start my lawnmower.

Very sorry to hear that.

When easy things like that become a problem, it's time to consider
a change in lifestyle. In this case, a new lifestyle where you don't
have to mow your own lawn.
Consider how long it will be before pushing the mower becomes too hard.
Pulling a starter cord on a mower is not all that hard.

Otherwise, buy one of those cordless electric mowers.
