A landing gear assembly for supporting a trailer has a drive mechanism for vertically extending and retracting a telescopic support (11). The drive mechanism has a two-speed gearing provided by gears on parallel input and output shafts which are axially relatively movable to change between the first and second speeds. In particular a drive gear (85) mounted coaxially on the input shaft (75) has an internal splined or toothed keying conformation (84), and a corresponding keying conformation (83) such as a smaller drive gear on the input shaft (75) can be slid into engagement with this for the second speed. Rotation of the horizontal output shaft (62) is converted to rotation around the vertical axis for operation of the support (11) by means of a bevel pinion (74) on the output shaft (60) engaging a corresponding bevel gear (34) of the conversion mechanism (25,26) in the support (11). The drive gears (72,73) on the output shaft (60) can be formed in one piece with the bevel pinion (74) on the same shaft.
