For a lawn that is more than 1/2 acre with multiple objects a zero turn mower would be a good choice. The time taken to mow your lawn can be cut in half with a zero turn mower as these mowers are more efficient. The excellent maneuverability allows you to easily mow around all size objects without having to back up and turn repeatedly. The rear wheels are used for both power and steering and operate independently so one wheel can reverse while the other wheel rotates forward allowing zero to 360 degree turns.
