What kind of lawn mower are you changing blades on?
Turn your blades off.
counterclockwise
Most lawnmowers loosen to the left. At least that's how I do it.
if you are sitting in the seat and looking down at the deck the blades will or should be turning clockwise, although in this position you cannot actually see the blades. pay attention when installing the blades not to turn them upside down. the cutting edge should be turninh clockwise on all blades.
Same as a car. Jumper cables, neg to neg, pos to pos, out of gear, turn blades etc off, start as usual
Zero turn lawn mowers can be either a riding lawn mower or a push lawn mower, depending on you're preference. Push lawn mowers start around three hundred dollars.

Zero turn mowers are riding lawnmowers. The design and features offered by a zero turn mower do not really translate into anything that would work well for a push mower. Several brands, such as John Deere and Snapper, offer zero turn (riding) mowers that are designed specifically for residential use.

Not on a push mower that has no electric start. On a riding mower, yes there is an ignition key.
