The small apple (hinge) 77.60.199 / 151.56.302 is used in the hitch of HTZ tractors and is designed to create a movable articulated connection of the lower links, ensuring free movement of the attachment during operation.
The hinge is installed in the lower right link 150.56.025-1 and the lower left link 150.56.026-1. It is equipped with two thrust rings 150.56.155-1 / 150.56.156-1, which ensure its correct fixation and reliable operation in the unit.
The part is made of hardened steel, which ensures high wear resistance, resistance to shock loads and long service life even during intensive use with heavy attachments. Thanks to the spherical design, the hinge compensates for angular displacements and reduces the load on the elements of the hinged system, increasing its reliability.
Used on tractors HTZ T-150K, T-151K, T-156, HTZ-17221, HTZ-159K, HTZ-242K, HTZ-245K, HTZ-248K, HTZ-249K and other models with a similar design of the attachment.
