PEAT TEDDER (EN: peat agitator; DE: Torfwender, Torfwendevorrichtung; FR: machine à remuer la tourbe, remueuse de tourbe; ES: maquina para remover la turba; RU: ворошилка торфяная) is the trailed device for the tedding of the milled peat crumbs, which are located within the loose layer. The first peat tedder has been created within the USSR during the 1931-32.

The peat tedder is the grouped trailer, which is moved using the wheeled or tracked tractor (with the engine with the power of at least 55 kilowatts). There are hinged to the trailer the tedding sections, which are equipped with the working elements, namely, blades, which are tedding, during the movement of the peat tedder, the strip of the peat with the width of 150 millimetres. The quality of the tedding depends significantly on the shape of the blade, on the pressure of the working element onto the deposition, and on the speed of the movement. For the regulation of the pressure onto the ground, the working elements are equipped with the removable and movable loads. For each structure of the working element, there is established the limited acceptable working speed for the movement of the peat tedder, in case of the exceeding of which, the quality of the tedding decreases. The modern sectional peat tedders have the width of the tedding of up to 19 metres, and the working speed of up to 25 kilometres per hour. There are most prospective the wide-area peat tedders with the extendable lateral sections. The lateral tedding sections of the peat tedder in the transport position (during the moving over the bridges, through the turns of the road, and so on) may be lifted or moved re arwards (behind the central sections) with the help of the hydraulic cylinders, which are connected to the hydraulic system of the towing tractor.
