downwardly from the frame 15 of the machine this secures the bottom of the stabilizer firmly in place fig1 shows the member 85 extending downwardly from frame 15 and bracket 84 extending inwardly from tube 52 when the boss 73 the bracket 85 and hydraulic hoses 67 and 69 are in place on vehicle 11 only three steps are required to install the stabilizer 10 of this invention on the vehicle the first is to hang the stabilizer 10 on the boss 73 the second is to operate nut 74 to secure the upper connection which also secures the bottom connection the third step is to attach two hydraulic hoses 66 and 68 which are parts of the stabilizer to the hoses 67 and 69 on the vehicle removing the stabilizer requires the same three steps carried out in reverse order when two of these stabilizers are used together they may be connected hydraulically as shown in fig1 to not only enhance the down pressure exerted on an implement at the other end of the vehicle and the braking effort but in addition to compensate for uneven terrain in fig1 the two stabilizer cylinders 60 are connected so that a hydraulic conduit 91 joins the head ends of the cylinders and a hydraulic conduit 93 joins the rod ends of the cylinders conduit 66 is connected between conduit 91 and a two way control valve 95 conduit 68 is connected between conduit 93 and control valve 95 when valve the 95 is operated to pressurize conduit 91 and thus the head ends of the two cylinders while pressure is released.
