A collection of technical terms which are useful for navigating your way through the jargon jungle of the gardening world.
Anti-vibration system Vibration damping system which completely isolates the handles from the rest of the tool for maximum user comfort, even during prolonged use.
Quick Fit system System which allows quick attachment and removal of the cutting deck and other accessories in just a few minutes, without the need for tools.
Motorstop Automatic safety device which instantly stops the engine and moving parts when needed.
Turning radius Radius or diameter of the arc-shaped path travelled by the front wheels with the steering wheel turned full lock.
Handgrip rotation (180°, 90° clockwise and 90° anticlockwise) System which ensures maximum versatility of use, even close to walls.
Variable speed control System with enables the machine to operate over an infinite range of speeds, making it adaptable to any type of grass.
Cutting width The cutting width depends on the cutting deck of the machine, in relation to the expanse of the area to be cut.
Propulsion Can be push-type, for smaller areas, or self-propelled for larger areas.
Bearing Mechanical device which reduces friction in the wheels. Wheels mounted on bearings ensure consistently smooth running, even over the most uneven terrain.
Cylinder The cylinder is the component used to create linear motion; the area in which the combustion process takes place.
Piston The moving component, housed inside the cylinder and connected by means of the gudgeon pin to the connecting rod, which forms a "mobile wall" of the combustion chamber.
Connecting rod Part of the connecting rod-crank mechanism, e.g. the mechanism which enables alternate rectilinear motion to be transformed into continuous rotary motion.
Transmission The set of components which transfer the power generated by the engine or motor to the wheels.
Digital coil Generates high-voltage current, which when it reaches the spark plug creates the spark which triggers combustion.
Oil pump Draws lubricant from the sump and sends it to pressurised components in the engine lubrication circuit.
Air filter Component which protects the engine by preventing dust from entering the cylinders.
Crankshaft A rotating mechanical shaft with a series of cranks which enables the movement of the connecting rods is transmitted to the power take-off.
Catalytic muffler A device installed in the initial section of the exhaust system which drastically reduces the quantity of pollutants (carbon monoxide, hydrocarbons and nitrogen oxides) present in the combustion gases.
Bevel gear A transmission system with helical gears which transfers movement to the cutting assembly, parallel to the ground, with suitable speed reduction.
Drive belt A drive belt is a mechanical transmission component looped over pulleys which is used to provide an elastic but solid link between two rotating shafts.
Rotor A component which rotates inside the stator and which transmits motion to electrical machines.
Lockable differential The differential is a device which enables two wheels to move at different speeds. Locking the differential prevents one of the two drive wheels from spinning in the event that it temporarily loses grip.
Casing Metallic enclosure which protects the engine components.
Handlebars Leverage system which enables the equipment to be kept under control.
Power take-off The power take-off or PTO consists of a connection at the back or front of the machine to which implements are attached.
Grease nipple System which simplifies periodic replenishment of lubricant grease in the gearbox.
Reduction unit Assembly used to transmit rotary motion with a reduction in the number of revolutions.
Fuel tank Container for storing fuel inside the machine.
Starter rope handle Handle connected to the recoil starter rope which is used to start the engine.
Carburettor Mechanical part of internal combustion engines which blends air and fuel for injection into the combustion chamber.
Mixture Mixture of lubricant oil and fuel which is usually used in two-stroke engines. This mixture is important because it lubricates the mechanical components of the engine and provides a source of energy.
Expansion clutch Transmits movement to the cutting implement and also enables it to remain stationary at idling speed without having to stop the engine.
Dipstick The dipstick, present in 4-stroke engines, is immersed in the oil and is used to check the level (MIN and MAX with graduated scale) and quality of the oil.
