Abstract: Изобретение относится к лесопожарной технике, а именно к ротационным рабочим органам орудий, работающим по принципу поперечного фрезерования почвы, и предназначено для прокладки минерализованных полос. Режущая кромка ножей, установленных на диске, выполнена в виде участка спирали с радиусом, нарастающим от минимального до максимального радиусов. Угол между минимальным и максимальным радиусами равен 90-180°. Ножи установлены на диске так, что угол между задней кромкой ножа и плоскостью вращения фрезы равен 7-15°, и повернуты относительно задней кромки в сторону движения на угол, равный 7-15°. Это позволит снизить энергоемкость и повысить качество прокладки полос. 5 ил.
