jõuvõtukohad

Jõuvõtukohad is an Estonian term that translates to "power take-offs" or PTOs. In the context of machinery and vehicles, a PTO is a standardized mechanism that allows an engine's power to be transmitted to auxiliary equipment. This is most commonly seen in agricultural and construction machinery.

A PTO typically consists of a shaft that extends from the transmission or engine of a prime mover, such as a tractor or truck. This shaft rotates at a specific speed, usually dictated by the engine's revolutions per minute (RPM). The rotating PTO shaft can then be connected to a driven implement using a driveline, such as a universal jointed shaft. This allows the implement to receive the rotational power needed to operate, for example, a mower, a baler, a pump, or a snow blower.

The primary advantage of a PTO system is its efficiency and simplicity in transferring mechanical power. It eliminates the need for separate engines for each piece of auxiliary equipment, making machinery more versatile and cost-effective. Different PTO standards exist globally to ensure compatibility between various types of equipment. Common PTO shaft speeds include 540 RPM and 1000 RPM, with variations also existing for specific applications. Safety is a critical consideration with PTOs, and guards are always used to prevent accidental entanglement.
