How a lawnmower transmits power

Two pairs of power transmission belts are installed on the power take-off pulley. The forward belt transmits the power to the cutting system, which is called the cutting power belt, and the backward belt transmits the power to the walking system, which is called the walking power belt. The cutting power belt is connected to the cutting system through this rotating wheel. This is a pinch pulley, which is connected to a pull wire switch. When the pull wire switch is tightened, the pinch pulley compresses the transmission belt, and the power of the engine is transmitted to the cutting system.

When the cable switch is slack, it cuts off the forward transmission of power. A pinch pulley is also installed on the side of the walking power belt. The pinch pulley is connected to a pull wire switch. When the pinch pulley is in this position, the belt is in a relaxed state, and the power of the engine cannot be transmitted backwards. Similarly, tighten the pull wire. When switching, the pinch pulley approaches and compresses the power belt, thereby transmitting the power of the engine to the rear rotating pulley, which is connected to the gearbox.

This is the gearbox, which contains several sets of gear combinations. Through different combinations of gears, the adjustment of the engine speed and rotation direction is completed. For the gearbox, this rotating wheel is its power input, and the gear combination inside the gearbox is driven by this speed change The lever operation is complete, this is the power take-off shaft of the gearbox, which sends the power to the walking system. The power system transmits power to this rotating wheel through belt drive, the rotating wheel is connected to the header part, the gear box is installed in the header, the circular cutting disc is connected under the header, and the cutting disc is evenly installed.

Three cutting knives, three cutting knives are evenly installed on the reel of the header, and the cutting table drives the circular cutting disk to rotate at high speed. The Lawn Mower Spindles header is connected to the machine frame through these two connection points. The position of the upper connection can be changed. By changing the position of these two screws, the ground clearance of the header can be adjusted appropriately to achieve the purpose of adjusting the height of the stubble.This is the shield of the header, which is connected to the frame.
