摘要：
The invention relates to an agricultural equipment consisting of a framework, a transmission which ensures the mechanical auto trip of the working member, a chopping drum with oscillating cutting tools, subjected to overload, which is mounted to the tractor coupling bars, the claimed equipment being intended to cut stalks of plants, such as weeds or crop plants. According to the invention, the equipment comprises a metal framework (), provided with a system () for coupling the same to a tractor, a main transmission () with step-up gearing, some belts (), a chopping drum () with oscillating cutting tools, some land copying drum shoes (), the overload trip mechanism consisting of a belt idler () oscillating about the point (), thereby tensioning the belts () by stretching a spring () mounted on the roller () articulated on a center (), an indexing device () mounted on the same roller (), which comprises a slide with the distance adjustable by means of a not positioned spring and two nuts by means of which the spring tension is adjusted so that, by increasing the effort, the transmission belts () are tensioned and move the stretcher () which acts upon the spring () rotating the drum () and compressing the spring within the indexing device () making the drum swing, the transmission auto trip being achieved by removing the belt idler ().Invenţia se referă la un echipament agricol constituit dintr-un cadru, o transmisie care asigură decuplarea mecanică automată a organului de lucru, un tambur de tocare cu cuţite oscilante, supus la suprasarcină, care se montează pe tiranţii tractorului, echipamentul fiind destinat tăierii tulpinilor de plante cum sunt ierburile sau plantele de cultură. Echipamentul conform invenţiei este compus dintr-un cadru () metalic, prevăzut cu un sistem () de cuplare pe tractor, o transmisie principală () cu multiplicator, nişte curele (), un tambur () de tocare cu cuţite oscilante, nişte patine () cu tambur pentru copierea terenului, mecanismul
