the lever and hence the wheel in this direction in operation and when it is desired to move the implements from a straight ahead position shown in fig7 to the full transport position shown in fig8 wheel assemblies 17 are unpinned rotated through approximately 90 u00b0 and then re pinned support wheels 18 are also unpinned and are therefore free to castor the tractor then slowly drives forwardly as the fluid operators 49 and 59 are actuated the fluid operator 59 swings the connector around to the position shown in fig8 and the fluid operator 49 moves the front portion 47 of the front and rear hitch poles to the position shown in fig8 so that the second implement 11a takes up a position substantially in line astern with the first implement as illustrated the movement of the connector 52 forces the wheel assembly 60 to move so that the wheel 61 is in alignment with the direction of travel of the entire assembly in the full transport position the pressure of spring 64 against the stop 65 limits the movement of the wheel assembly in this direction as mentioned fig7 and 8 show the device attached to the frame member 13 but it can be attached to members 24 whether they be as illustrated in fig2 or bolted to the frame 13 as hereinbefore described referring back to diagonal member 26 fig2 the front connections should be such that the brace can move up and down as wheel 28 rides over the terrain the preferred method not illustrated is to connect the brace by means of a pivot pin substantially in alignment with the pin at 25 it will also be appreciated that telescopic adjustable tubing can be substituted for the.
