The lever bolt 77.60.174-1 is a fastening element designed to connect the lifting levers to the brace earrings in the hitch of HTZ tractors. It is used both in the new type of linkage system (hook type) and in the old type of linkage system (for one hydraulic cylinder). In the first case, it is used with left lever 172.56.151-01 and right lever 172.56.151, in the second - with left lever 150.56.151A and right lever 150.56.152A.
The bolt passes through the hole in the lever and fixes the brace shackle 77.60.164-1A, ensuring the strength of the connection and the transmission of force from the hydraulic cylinders to the attachments. Used on all versions of HTZ tractors, including T-150, T-150K, T-156, T-17221, T-17021, T-17021-05 and other models with a similar attachment design.
