Who handles lawn maintenance

[Steve Colonnello]

I am looking to purchase my first rental property. 

It is a single family home, with a lawn (totally flat). Nothing to large. Would estimate 30 minutes using push mower.

The property has a shed.

Whose responsibility is it to mow the lawn? Mine, as the landlord, or the tenant?

Should I supply the lawn mower?

Is it best to pay a service and pass the cost through on the rent?

Thanks in advance.
