#BLADE STOP LAWN MOWERS PLUS#

This motion, plus the enclosed space of the mower deck, creates a vacuum, sucking up the grass as the mower passes over it. Instead, there are tabs on the ends of the blade that curve up slightly, which produce lift and suction. If youвЂ™ve ever taken a peek at the cutting blade on your lawn mower, you might have noticed how itвЂ™s not just a straight, flat blade all the way across. So your lawn mower has to account for that. Grass doesnвЂ™t stay in position when you swipe something over it-itвЂ™s so light that it moves out of the way. Think for a second how grass would react to a spinning blade. ItвЂ™s a convenient way to turn the mower off when youвЂ™re done mowing, but more importantly, itвЂ™s a safety feature that can prevent serious injury in the event that you trip or fall while mowing. The moment you let go of it, the engine will shut off and the blade will stop spinning. This is called the blade control handle or brake bail arm. The Blade Control Handle Is a Crucial Safety FeatureДЄll lawn mowers require you to press and hold down some sort of lever near the hand grips in order to start and run the engine. And the carburetor is fairly low-maintenanceВ with the proper care, like adding stabilizer to the fuel and never letting the fuel sit in the engine for more than a few months- old gas can decompose inside the carburetor and clog it up in no time. The engine is the most important component on a lawn mower, and it needs to be treated as such with regular maintenance, like changing the oil and replacing the spark plug and air filter. But on a lawn mower, that rotation is directly transferred to a cutting blade.ДЄ cutaway animation of a basic internal combustion engine, very similar to the one on your lawn mower. (A typical engine on a walk-behind mower is about 150 cubic centimeters in size, whereas the engine in a compact car is over ten times that.) On a car, the engineвЂ™s rotation is transferred to the wheels. ItвЂ™s very similar to the engine in your car, only smaller. The ignition of the air and fuel mixture results in a controlled explosion that drives a piston down and rotates a crankshaft. It also provides momentum to keep the engine rotating between combustion cycles. The flywheel also serves as a cooling fan (thanks to fins attached to it) and as a shock absorber (when the blade hits a rock or tree roots). As it spins, magnets attached to the flywheel pass over an ignition coil to create a magnetic field, which generates electricity and sends voltage to the spark plug. This mixture is ignited by a spark plug, which gets its electricity from a flywheel that rotates along with the engine. The inner workings of a carburetor, which mixes air and fuel and sends it into the engine to be ignited.
