FIELD: agricultural engineering.
SUBSTANCE: invention relates to linkage mechanisms of agricultural, timber and irrigation machines. Proposed tractor linkage contains upper link with hydraulic cylinder connected to link through bracket, lower links, linkage rod connected with rod of hydraulic cylinder, adjustable rod connected with linkage rod by means of articulated joint with axle, shanks and control mechanism. Shank is made in form of bellcrank hinge-connected with linkage rod and lower link and it is provided with plow connecting member. Adjustable rod has longitudinal slot accommodating axle of articulated joint and it is provided with lock. Linkage rod has stop to engage with lock. Limiting chains are used to limit lifting of front part of plow. Proposed linkage increases capacity and improves quality of plowing by providing following of soil surface by plow irrespective of angular oscillations of tractor, improves reliability of hydraulic cylinder and fastening of plow at its lifting and transportation owing to rigid fixing of plow relative to linkage.
EFFECT: increased capacity of tractor.
