Buy brush cutter

An electric brush cutter is the perfect cordless garden tool if you have an allotment, or you need to control or clear larger areas of overgrown brambles, weeds and shrubs.
The machine can reduce selected trees and shrubs quickly to ground level while minimizing root disturbance. The brush cutter is designed to save time and energy by cutting and treating vegetation in a single operation. The shredded material is rapidly biodegradable mulch that can help reduce erosion and provide soil nutrients and fertility. Shrubs that are more desired on the landscape, such as those considered beneficial for mule deer winter range, can remain untouched.

Brush cutters are similar in appearance to line trimmers, but a trimmer uses a thin nylon string that cuts vegetation such as long grass or weeds, while a brush cutter uses a metal blade that cuts through dense vegetation and tree trunks up to 4 inches thick. Brush cutters offer more power and versatility than trimmers, but they have some disadvantages to consider as well.

A brush cutter is more suited to tougher jobs which your line trimmer may not be able to handle. Areas you may need to use an electric brush cutter could include:

Thick vegetation
Tall, rough grass and weeds
Brambles, bushes and shrubs
Small hedges with thin trunks

Ease of Use
One of the biggest drawbacks of a brush cutter is learning the cutting techniques necessary to avoid injury or damage to the machine. Brush cutters have a specific cutting area, which means you can’t just hack into vegetation from any direction. The blades rotate counterclockwise, so you must move from right to left when cutting.

The cutting zone is from the top of the blade to 90 degrees left; if you hit a thick stem or branch with any other part of the blade, the machine may kick back at you. Feed the blade into the brush or vegetation slowly, so the head is pressed against the material rather than swung at it. If you use a chopping motion to cut with a brush cutter, the machine may smoke and stop working because branches and other material may bind around the blades, causing it to overheat.

a brush cutter consists of:

A power unit held close to the body.
A pole through which the power is transmitted.
A rotary cutting head at the opposite end of the pole to the power unit.

Two Stroke Engines v. Four Stroke Engines:
For our purposes, 2 stroke engines tend to be more powerful than 4 stroke engines. And since they have less moving parts, 2 stroke engines tend to be more reliable.

In choosing between a two-stroke or a four-stroke, four-stroke engines tend to be better on fuel, quieter, and less emissions. At the time of this writing, four stroke engines are more expensive. Two-stroke engines are generally more powerful than four0stroke engines thus tw0-stroke engines are worse on fuel economy, have worse emissions. What they lose in fuel economy and emissions, they make up for in price and more reliability because they have less moving parts.

And speaking of less moving parts, the 4 stroke has a separate oil pan to lubricate the engine. Many lawnmowers are 2 stroke engines and generally cut grass flat on the ground. A brush cutter or a string trimmer often has to be tilted and held at odd angles in order to do its job. That tilt can result in oil moving out of where it needs to be, exposing the engine to greater wear or even damage.

Q. Do I need anything special when I gas up my brush cutter?

A. Two stroke engines, because they have no oil pump, require require gasoline plus some oil. If you run a two stroke engine without adding oil, the engine will seize up and you are going to be in for an expensive repair.

Q. Do I need special gasoline or will any gasoline work?

A. For most of these brush cutters the manual specifies the use premium gasoline with no ethanol in addition to the fuel oil. My research has uncovered that many lawn care professionals will use whatever gas is available.
