A tractor hitch (10) comprises a pair of lower links (12) pivoted on a chassis (11) of a tractor. Each lower link (12) has lift rod (15) connected with a hitch actuator (17a) which is used to raise the lower links (12) relative to the chassis (11). Each lift rod (15) is provided with a means (18,20) for shortening its effective length in a stepwise manner so that the lower links (12) can be raised to a higher position relative to the tractor chassis (11) when the hitch actuator (17a) is used.
