Abstract
A mid-mount type riding lawn tractor includes tractor frames, a mower unit disposed under the tractor frames, and a connection structure for vertically movably connecting the mower unit to the tractor frames. The connection structure includes support arms extending substantially longitudinally of the tractor frames, each of the support arms being pivotally connected at one end thereof to a lower position of one of the tractor frames, and at the other end to a portion of the mower unit, interlocking links each pivotally connected at one end thereof to a position of the mower unit closer than the portion of the mower unit to the position of connection between the support arm and the tractor frame, each of the interlocking links having a free end, and seesaw arms. Each seesaw arm has an intermediate connecting portion pivotally connected to an intermediate position of one of the support arms, a first arm portion extending in one direction from the intermediate connecting portion, the first arm portion being pivotally connected at a distal end thereof to the free end of the interlocking link, and a second arm portion extending in a different direction to the first arm portion from the intermediate connecting portion, the second arm portion having a contact for contacting one of the tractor frames from below.
