An adjustable length strut 24 for laterally supporting each lower steering arm 12, 14 of a three point linkage on an agricultural tractor comprises a sleeve 26 within which a shaft is telescopically slidable, the two parts being biased inwardly towards one another by a tension spring 40. The shaft 28 is provided with axially spaced through bores 52, 54, 56 each alignable with a corresponding through bore 58, 60 or 62 in the sleeve 26. The longitudinal axes of each alignable set of bores extends at different angles of inclination to one another whereby a locking pin 64 may only be insertable through one specific set of aligned bores.
