1、体积小、重量轻、结构紧凑、坚实可靠。
The small size, light weight, compact, solid and reliable.
2、润滑性能好：采用箱式封闭结构，齿轮飞溅润滑，一次加油可连续作业一个月以上，(油面应不低于油标刻线，使机械始终处于良好的润滑状态)。
Good lubrication: adopt the closed box structure,gear splash lubrication, a refueling operation can
work one more than month. (The oil should not be less than marking lines, always in a good state of mechanical lubrication).
3、功能损耗少：因润滑条件的改善，齿轮轴端采用滚动轴承，阻力小。
Less functional loss: because of changing the lubrication, the end of gear axis use rolling bearing,
the resistance small.
4、移动方便，前轮转向，机动灵活，维修方便。
Move convenience, front wheel make turn, flexibility easy maintenance.
