为满足山地造林的需要,零陵地区林机厂在省地科委和林业厅局的领导下,经过五年的努力,研制成功了一种小型、适用于荒山整地和林间垦复的HHl2型多用山地手扶拖拉机(原名YK12D型) (见图)。现将该机的结构原理和性能简介如下。一、底盘该底盘为可变型手扶拖拉机底盘。它与手扶拖拉机不同之处是加装一后轮部件而成为滑移转向四轮驱动,拆去后轮部件,将前轮换成胶轮就又恢复成手扶拖拉机,挂上拖车可以在公路上运输(在山地中运输可直接在四轮驱动
In order to meet the needs of afforestation in mountainous areas, under the leadership of the Provincial Science and Technology Commission and the Forestry Bureau, the Lin-Ling Plant in Lingling District succeeded in developing a small-scale HH12 that is suitable for barren mountain preparation and forest reclamation after five years of hard work. Multi-purpose mountain walking tractor (formerly YK12D type) (see photo). Now the machine structure principle and performance are as follows. First, the chassis The chassis is a variable tractor tractor. It is different from the walking tractor is the installation of a rear wheel components into a slip-steering four-wheel drive, remove the rear wheel parts, the front wheel into a rubber wheel and then restored into a walking tractor, hanging trailer can be Road transport (In the mountains in the transport can be directly driven in four
