Abstract: A mower deck suspended stably from a lawn mower frame by a four link frame of a front hanger and four link frame of a rear hanger. The height of the mower is adjusted when a handle is pushed forward to rotate a rotatable axle in a clockwise direction, which causes a driving lever to rotate in a clockwise direction. A fine adjustment screw pushes a swing arm to rotate rearward, which forces a bridging swing arm to rotate in a clockwise direction via a second link. The bridging swing arm forces the first link to swing upward which forces the rear end of the rear hanger to swing upward, thereby raising the mower deck. When the handle is pulled rearward, the mower deck will be lowered.

Abstract: A raising and lowering mechanism for a mower deck of a lawn mower including a front hanger and a rear hanger; the front hanger and the rear hanger each are, independently, a four link frame, with a front end of the front hanger and a front end of the rear hanger being hinged, independently, to the frame of the lawn mower, and a lower portion of a rear end of the front hanger and a lower portion of a rear end of the rear hanger being hinged, independently, to a top portion of the mower deck; a first link is hinged to a middle portion of a rear link of the four link frame of the rear hanger, and an upper end of the first link is linked to an lower end of a bridging swing arm, with a middle portion of the bridging swing arm being hinged to the frame of the lawn mower via a spindle; an upper end of the bridging swing arm is hinged to a rear end of a second link, and a front end of the second link is hinged to an upper end of a swing arm, with an lower end of the swing arm being connected to a rotatable axle and a

Abstract: The present invention relates to a garden machine. More specifically, the present invention relates to a pedal-driven lawn mower.
