Abstract

The invention relates to a separable lower end consisting of a locking pin and a box pin designed for a tractor including a stop mechanism, in which the locking pin is less likely to become entangled in the lobe of the tractor during the locking pin's engagement with the tractor, even when the locking pin and box pin are combined with a different type of tractor using a stop mechanism of different configuration. The separable lower end (1, 2) according to the invention consists of a locking pin (30), a box pin (50), the first tractor of the reverse opening type (10a, 70a), and the second tractor of the forward opening type (10b, 70b). The first tractor (10a, 70a) includes the lobe (22, 82) which is permitted to advance into and withdraw from the locking pin path (17). The box pin (50) consists of the box pin body (53) attached to the locking band, and the bulge (55) bulging out in width from the box pin body (53) toward the lug (22, 82) of the first pull head (10a, 70a) held in the sliding limit position.
