1. Side-mounted brush cutter.
It adopts hard-shaft transmission, mainly composed of engine, transmission system, clutch, working parts, manipulation device and side-hung belt. At one end of the drive shaft is equipped with a single-cylinder two-stroke air-cooled gasoline engine of 0.75-2 kw and centrifugal friction clutch; at the other end is installed the working parts consisting of reducer and cutting tool.
There are many types of working parts, commonly used for circular saw blades, blades or nylon grass head. When operating, the hook ring on the aluminum alloy casing of the drive shaft is hung on the back belt under the operator's shoulder, holding the handle and swinging the hard shaft laterally to complete the work of cutting weeds and shrubs. The machine weighs about 6-12 kg, and the speed is about 4500-5000 rpm.
2. Backpack brush cutter.
With a soft shaft drive, the general structure is similar to the side-mounted brush cutter, the difference is that its engine back in the user's back, cutting parts by the soft shaft drive, engine power is generally 0.75-1.2kw. The engine is generally 0.75-1.2 kW. The engine is connected to the back frame by two points and is equipped with special rubber parts for vibration isolation. Flexible shaft is a set of steel wire flexible shaft in the hose, to transfer torque. The hose is a threaded pipe wrapped in steel tape with a rubber protective sleeve and a metal braid to prevent dust from entering the shaft and to keep the shaft surface lubricated. The cutting width is generally between 1.5 and 2 meters.
