Lower link hook for tractor has swiveling spring-loaded locking plate which fixes coupling in place and cooperates with pivoting safety catch

摘要

The lower link hook (4) for a tractor has a spring-loaded locking plate (6) which fixes a coupling in place. This is pivoted on a pin (11) and cooperates with a safety catch (23) pivoted on a second pin (24). A spring (13) biases the locking plate so that its inner surface (27) cooperates with the safety catch.
