Not necessarily when to change; but when to sharpen mower blades: The easiest way to know is by observing the way the grass is cut. A sharp blade will make a "clean cut" on the grass blades, whereas a dull blade will "tear" the grass and leave a "ragged" appearance.
As far as when to change out the blades, there is no set time interval, you just have to visually evaluate the condition of the blade (bent, badly worn, warped, etc.) to determine when to change. If your mower uses 2 blades, it would be wise to change both blades at the same time.
You can lift a riding lawn mower with a car or floor jack in order to change the blades. Simply place the jack under the frame of the lawn mower but away from the blades to lift it. Then, block the mower up using bricks or concrete blocks.
