Riding type mower

Abstract

A riding type mower comprises: a plurality of wheels including at least one driven wheel; a vehicle body supported by the plurality of wheels; a driver's seat supported by the vehicle body; a mower unit located below the vehicle body; a suspension mechanism for vertically movably supporting the mower unit from the vehicle body, the suspension mechanism having a restraint member operatively connected to the suspension mechanism; an operation mechanism for operating the suspension mechanism; a stopper for setting a lower limit for a vertical position of the mower unit to define a cutting height by abutment against the restraint member, the stopper is adapted to be rotated to change the lower limit; a lower limit adjustment element located laterally of the driver's seat and rotatable to rotate the stopper; and a linking mechanism for operatively connecting the lower limit adjustment element with the stopper.

Claims

1. A riding type mower comprising: a plurality of wheels including at least one driven wheel;a vehicle body supported by the plurality of wheels;a driver's seat supported by the vehicle body;a mower unit located below the vehicle body;a suspension mechanism for vertically movably supporting the mower unit from the vehicle body, the suspension mechanism having a restraint member operatively connected to the suspension mechanism;an operation mechanism for operating the suspension mechanism;a stopper for setting a lower limit for a vertical position of the mower unit to define a cutting height by abutment against the restraint member, the stopper is adapted to be rotated to change the lower limit;a lower limit adjustment element located laterally of the driver's seat and rotatable to rotate the stopper;a linking mechanism for operatively connecting the lower limit adjustment element with the stopper.

2. A riding type mower according to claim 1, wherein the lower limit adjustment element is rotatable about a first axis and the stopper is rotatable about a second axis, wherein the first axis is located laterally outwardly with respect to the second axis and the linking mechanism transmits a rotating motion about the first axis as a rotating motion about the second axis.
