Hydraulic adjusting system for lower connectors (1) of tool mounting system on tractor comprises side bars with outer (7), intermediate (6) and central (5) sections. These form part of hydraulic cylinder (3) and their lengths can be adjusted relative to each other. When outer section is fully extended and other sections fully retracted, distance (K3) between free ends of connectors corresponds to standard width of the tool (G). |
