Moreover, the first surface 106 corresponding to each of the disks 104 magnetically engages the outer surface 26 of the housing 16 corresponding to the seed treater 12. In this way the mounting unit 38 is releasably coupled to the housing 16.


The plurality of disks 104 includes a first disk 110, a second disk 112 and a third disk 114. The first disk 110 is positioned on the forward surface 74 of the third member 68. Each of the third 114 and second 112 disks is positioned on the front surface 60 of the second member 54. A plurality of third fasteners 116 is provided and each of the third fasteners 116 engages an associated one of the disks 104. The third fastener 116 corresponding to the first disk 110 is extended through the fifth aperture 75 in the third member 68. The third fastener 116 corresponding to the second disk 112 is extended through the third aperture 64 in the second member 54. The third member 68 corresponding to the third disk 114 is extended through the fourth aperture 66 in the second member 54.


In use, each clamps 80 is coupled to the manifold 28 and the receiver 94 corresponding to each of the clamps 80 is coupled to the first member 40. The mounting unit 38 is positioned on the seed treater 12 such that the first member 40 extends through the aperture 20 in the drum 18. Additionally, the mounting unit 38 is positioned on the housing 16 to centrally position the manifold 28 in the drum 18 thereby facilitating the manifold 28 to dry the seeds 14 in accordance with the manufacturer's specifications. Each of the disks 104 magnetically engages the housing 16 to retain the mounting unit 38 on the seed treater 12. In this way the mounting unit 38 is releasably coupled to the seed treater 12 without the use of penetrating fasteners or other mechanical fasteners. Thus, the mounting unit 38 does not inhibit rotation of the drum 18 in the housing 16. The mounting unit 38 is removable at any time from the housing 16 thereby facilitating the seed treater 12 to be serviced and cleaned.
