and 72 for lifting the cradle 36 and thus the bulk fill assembly 30 cylinder 70 is interconnected between forward knuckle 62 and a rearward knuckle 74 as shown in fig5 the rearward knuckle 74 includes or is coupled to a mounting arm 76 that is coupled to axle 78 about which wheel 46 rotates cylinder 70 includes a ram 80 that is coupled to the rearward knuckle 74 whereas cylinder 70 is coupled to the forward knuckle 62 in a similar fashion cylinder 72 includes a ram not shown connected to a rearward knuckle 82 whereas the cylinder 72 is connected to the forward knuckle 64 it will be appreciated that a mounting arm 84 is connected to or formed with the rearward knuckle 82 and the mounting arm 84 is connected to an axle not shown about which wheel 48 rotates fig6 shows the central bulk fill assembly 30 in the raised for transport position the bulk fill assembly 30 is raised from the lower field or working position by the actuation of cylinders 70 and 72 in a preferred embodiment the cylinders 70 72 are linked to the hydraulic system that raises and lowers the stack fold planter 12 thus the central bulk fill assembly 30 is automatically raised and lowered as the planter 12 is raised and lowered it is contemplated however that the bulk fill assembly 30 could be raised and lowered independent of the stack fold planter additionally it is contemplated that a separate hydraulic system could be used to raise and lower the central bulk fill assembly 30 the following description details how the central bulk fill assembly 30 is raised.
