WIPO Patent Application WO/2018/165778
Kind Code:
A1
Abstract:
A three-wheel lawn mower having a single front wheel (t1) and dual rear wheels (227) which use a same rod to synchronise parallel connection rods to adjust the height. A height adjustment long rod (224) is connected to a front wheel height adjuster and a rear wheel height adjuster. The front wheel height adjuster is mounted above the front wheel (t1), and includes a parallelogram height adjustment structure provided with the parallel connection rods. An upper horizontal edge and a lower horizontal edge of the parallelogram height adjustment structure are parallel and equal, and a front parallel connection rod and a rear parallel connection rod are movable and constantly parallel. Rotating an angle causes the vertical distance between the upper horizontal edge and the lower horizontal edge to change, thereby adjusting the height.
