Choosing the right parts should not only consider the scope of use of the brush cutter, but also needs to be determined according to different brush cutter types, terrain and grass growth patterns. Let's have a look at the parts of the brush cutter with you!

Gasoline grass cutting accessories and spare parts

1. Clutch: The clutch drum of the grass trimmer and the chain saw are slightly different. The chainsaw clutch drum is fixed on the crankshaft, and the clutch block is transferred when the crankshaft rotates in high speed, when the centrifugal force is higher than the elastic force, the clutch blocks hold the clutch drum tightly. The clutch of grass trimmer is fixed on the fly wheel, there is a spring pad between the two parts, the centrifugal force is higher than the elastic force when crankshaft rotates in high speed, the two clutch blocks hold the clutch passive disc tightly.

2. Carburetor: The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum state generated by the engine operation. It uses the kinetic energy of the inhaled air flow to achieve the atomization of gasoline, and it is called the heart of the engine.

3. Gearcase: The gearbox assembly is attached to the end of the mower drive shaft, and the trimmer head is attached to the gearbox. Internally, it has several gears that change the shaft angle and set the speed of the trimmer head. Over time, gears wear and fail, and the bearings can fail and seize.

4. Connector Assembly: A component used to connect the clutch drum and the drive shaft, including the clutch drum, the connecting plate, and the connecting plate housing.

5. Cylinder: A cylindrical metal part that guides the piston to reciprocate linearly in the cylinder. Air in the engine cylinder converts thermal energy into mechanical energy through expansion; gas is compressed by the piston in the cylinder compressor to increase the pressure.

6. Grass cutting rope: The professional name is the cutting line, also called the trimmer line, which is a consumable accessory for the operation of the grass trimmer. Common specifications are 2.4 mm, 2.65 mm, and 3.0 mm.

7. Recoil starter kit: starter device, which includes puller cover, coil spring, rope pulley, handle, and rope. The starting end of the small gasoline engine and diesel engine is equipped with a start puller, and the engine is started by a small amount of starting power given by the start puller. Most of the existing recoil starters are the claw type, that is, when the puller rotates, the mechanical structure urges the claw to turn out of the puller, so that it is matched with the locking mechanism installed on the shaft end of the motor. Then the engine starts when the shaft rotates with the rotation of the pull disc.

8. Piston, piston ring, and circlip: The piston is the part that reciprocates in the engine cylinder block. Circlips, also known as retaining rings or e-clamps, are a type of fasteners that are installed in the shaft grooves or hole grooves of machines and equipment, and play a role in preventing the axial movement of parts on the shaft or holes.

9. Crankshaft: The crankshaft is the most important component of an engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the combined action of the centrifugal force of the rotating part, the inertial force of periodically changing gas, and the reciprocating inertial force, which makes the crankshaft bear the bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the inner surface of the bushing needs to be wear-resistant, work evenly, and have good balance.

10. Trimmer Head: The trimmer head plays a central role by using strings that get straight and stiff while spinning and cutting through the grass. These trimmer heads will eventually stop working after a long time of use, so the trimmer head needs to be replaced wholly or just change the trimmer line inside into a new one. The best trimmer heads could feed the line automatically to make sure the grass lawn trimmed is neat and flat.

11. Throttle control lever and handlebar: handlebar assembly. For operating the lawn mower, it consists of a left handle and a right handle. The right handle has an operation portion, a linkage mechanism, a high-speed control portion, a lock mechanism, and a lock mechanism release portion.

12. Blades: Special blades for grass or bushes cutting, they are two teeth blades, three teeth blades, square four-toothed blades, round blades with more teeth, etc. Different types of brush cutter blades are best for cutting different kinds of plants: Blades with 8 teeth or less: grass and weeds. Blades with 9-40 teeth: Thick weeds and shrubs. Blades with more than 40 teeth (also called circular saws): bushes, small trees and saplings.

13. Straps and Racks: Particularly suitable for shoulder and knapsack mowers or brush cutters, the part that fixes the grass trimmers on the back or on the shoulder.
