Systems and methods are provided for use in treating seeds. In one example embodiment, such a system includes a keg assembly including a seed treatment and a seed treater in fluid communication with the keg assembly via a supply line. The seed treater includes an application chamber configured to receive the seed treatment from the keg assembly via the supply line and apply the seed treatment to seeds. The system also includes a priming assembly coupled to the supply line and configured to automatically prime the supply line with the seed treatment, and a seed metering chamber configured to deliver an amount of the seeds to the application chamber based at least in part on a weight of the seeds received in the seed metering chamber.

Disclosed is a manual painting device (brush/roller) that allows surfaces to be coated continuously without the brush or roller having to be dipped manually in order to be loaded with paint. The kit can be mounted on a trolley/structure for transport or can be used in a backpack with a tank connected to a pump and from which the paint flows automatically, conveyed through a hose to the applicator element (brush/roller), such that the applicator element is loaded automatically from inside the painting accessory itself.

A fastener painting system is a system for painting a head of a fastener. The system includes: a cup for covering the head of the fastener by contacting an edge of the cup with a surface of the object; a supply system; a liquid discharging system; and a moving mechanism. The cup has a cavity for being filled up with paint. The supply system is configured to store the paint and supply the paint into the cavity of the cup. The liquid discharging system is configured to discharge surplus paint in the cavity out of the cup. The moving mechanism is configured to change a position of the cup relative to the object. The cup has a supply port for supplying the paint into the cavity, a vent for discharging air in the cavity out, and a liquid discharging port for discharging the surplus paint out of the cavity.
