Project on Brush Cutter (Grass Cutter PPT)
- 1. PROJECT ON BRUSH CUTTER PREPARED BY :- GOPAL SAW
- 2. CONTENTS :- INTRODUCTION HISTORY PARTS OF BRUSH CUTTER WORKING ADVANTAGE DISADVANTAGE APPLICATION Figure from Google Image
- 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.

- 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.
