Abstract
A simplified method of assembling a disk from the ground up by first assembling disk gangs and then connecting the disk gangs together to provide a self-standing front and rear main disk gang pairs. The main frame is assembled over main disk gang pairs after which wheel modules are attached. Disks of different sizes are assembled, utilizing generally identical main frame beams with the same connecting locations, by decreasing the distance between the forward and rear gang pairs and moving the main frame beams outwardly as the desired width of the disk increases.
