Abstract

An arrangement for engaging a differential lock in a vehicle incorporating a control unit (14) which firstly engages the differential lock via servo mechanisms (10) and secondly reduces the speed of the engine during engagement via an engine control unit (6). The control unit (14) incorporates a time delay circuit which ensures that the differential lock is engaged with a certain time delay after the engine speed has been reduced. The arrangement enables the engagement to take place quickly and automatically without the risk of the driving wheels of the vehicle spinning during engagement.
