ABSTRACT:
A lockable pedal arrangement having an operating pedal (14) which is movable between raised and depressed positions to perform a function such as the operation of a differential lock in a vehicle such as a tractor. The pedal is pivotally mounted on an operating member (10) and latching means (21a) associated with the pedal are engageable with fixed latching formation (21b) on movement of the pedal to its depressed position and pivoting of the pedal relative to the operating member. Detent means (17,19) at between the pedal (14) and the operating member (10) to hold the pedal in its pivoted position relative to the operating member (10) to maintain the latching means (21a) and latching formation (21b) in engagement and thus hold the operating member (10) in its depressed position.
When used as part of a differential lock operating system the lockable pedal arrangement may be associated with a lost motion device (32) which enables the pedal to be locked in its depressed position by the latching means (21a) before the locking formations (54,55) of the differential lock is actually able to engage.
