3. BRUSH CUTTER
 brush cutter is also known as string trimmer.
 brush cutter is a mechanical device which is cut the normal things like
grass and thin branches of small and big trees.
 It make quick work of under brush , berries , saplings, brambles, vines, tall
grass and small trees.
 It mainly consists of:
 A power unit held close to the body.
 A shaft through which the power is transmitted.
 A rotary cutting head at the opposite end of the shaft to the power unit.
 A wheel arrangement to hold the load of system.

4. HISTORY
 The brush cutter was invented in the early 1970s by George Ballas of Houston,
Texas, who conceived the idea while watching the revolving action of the
cleaning brushes in an automatic car wash. His first trimmer was made by
attaching pieces of heavy-duty fishing line to a popcorn can bolted to an edger.
Ballas developed this into what he called the "Weed Eater", since it chewed up
the grass and weeds around trees. And as day passing lots of modification has
been done on it. Currently we have various types of grass cutter available here
with various specifications on it.
 There are various types of power unit (engine):
 Gas engines either two/four stroke, are used.
 Petrol engines either two/four stroke, are used.
 Electric motors connected to mains power by a power cord.
 Cordless electric motors powered by rechargeable batteries.
 Solar energy-based power units.

5. PARTS OF BRUSH CUTTER
 Four stroke Petrol engine
 Fuel tank
 Drive shaft
Hallow shaft
 Handle
 Trigger Cable
 Trigger
 Gear head
 Blade safety guard
 Wheel
 wheel support pipe and rod
 Petrol, 2T Oil & Grease

6. ENGINE
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in
which the piston completes four separate strokes while turning the crankshaft.
A stroke refers to the full travel of the piston along the cylinder, in either
direction. The four separate strokes are termed:
 Intake
 Compression
 Combustion
 Exhaust

7. Flexible drive shaft
Flexible drive shaft deliver torque and
flexibility to reach inconvenient position.
FUEL TANK
 Fuel tank is safe container for flammable
fluids
 Its capacity to contain fuel is 1 l to 1000 l.
HANDLE
 Handle is used to start a engine
 It has a key which is match to shaft key of
engine so that we can start engine
 it is made of steel

8. GEAR HEAD
 It is setup of gears used to transmit the motion by
converting the liner motion which is coming from the
engine by shaft to the rotatory motion. It helps in the
rotation of blades which keep giving the rotatory motion
and helping to trim/cut the grass or bushes as per the
requirement.

9. BLADE SAFETY GUARD
 Safety guard is device which is used to protect from the
dust particle and blade to human being.
HALLOW SHAFT
 Hallow shaft is cylindrical in shape having length of 1.5
m or more according to the requirement.
 It has hollow rod.
 Its sued to support the whole machine by human.
 It uses to pass the flexible drive shaft inside the hallow
shaft to transmit the power or translation motion into
rotational motion.
GREASE
 Grease Is used to reduce wear and tear from the
machine component .it is also reduces to friction.
PETROL
 Petrol is used as fuel in internal combustion engine.

10. WORKING OF BRUSH CUTTER
 Brush cutter is a tool which uses a flexible monofilament line instead of a
blade for cutting grass and other plants near object .
 It consist of a cutting tip at the end of a long shaft with a handle.
 The line is hand wound onto a reel before the job is started , leaving both
end extending from the reel housing .
 The motor turns the reel and the line extends the horizontally while the
operator swings the trimmer about where the plats are to be trimmed
 The operator control the height at which the cutting takes place and can
trim down to ground level quit easily.
 For vertical cutting the whole machine can be tilted .

11. WORKING
 The internal
combustion engine
powering the brush
cutter is usually
located on the
opposite side of the
cutting head
 But , in the electric
power cutter , have
the electric motors
integrated into the
cutting head.

12. ADVANTAGE
 Brush cutter feature different
blade attachment that allow you
can cut a variety of material.
 Its RPM very high .less time
consuming machine.
 Brush cutter are easy to cut that
area where the other large
machine can’t reach.one person
can easily work by this.
 Less power consuming.

13. DISADVANTAGES
 One of the biggest drawback of a brush cutter is learning the cutting
techniques necessary to avoid injury or damage to the machine.
 Its blade RPM are very high 14-15k .so it is drive by trained person only .
 When it is working, cutting material produced some garbage can fly in
the environment which is harmful for our eyes.

14. APPLICATIONS
 To cut the grasslands
 Use to make many
designs on the trees
 To cut small braches of
the trees.
