Abstract
A towing mechanism includes a pair of brackets for receiving a drawbar therebetween, and a locking device. A towing bolt is received by locating bores in the brackets. The locking device includes a locking pin which is axially slidable in a pin bore in a component. The locking device is mounted on the upper bracket so that, in a locked condition, the locking pin projects out of the bore and prevents axial movement of the towing bolt. A blocking member at least partially covers the pin bore and prevents the extraneous material from contacting the locking pin, in order to reduce the likelihood of an unintentional release of the towing bolt.
