<p>A side strut 6 for the lower steering arm of a three-point attaching device of a tractor is telescopic and has a first telescopic member 14 and a second telescopic member 15 which are able to carry out relative movements relative to one another along an adjustment axis 16. A locking pawl 19 may allow maximum possible relative movement or a limited amount of travel. Complete locking is also possible. For setting the various positions which the locking pawl 19 is able to assume relative to the telescopic members 14, 15, a fixing device 31 is provided which takes account of the respective stop regions 24, 30 for the locking pawl 19 or which, for the purpose of allowing the entire relative movement between the maximum limits, may be disengaged from the locking stops 23. This measure, in addition to permitting standard adjustment within the limits of the usual floating movement, allows a limited floating movement. Furthermore, it achieves complete locking and fixing in this position.</p> |
