A seed meter includes an input port configured to receive a supply of seeds and an output port configured to deliver the supply of seeds for dispensing to a planting area and a seed disk configured to receive the supply of seeds from the input port and deliver the supply of seeds to the output port at a substantially uniform rate. The seed disk has a seed side where seeds flow from the input port, and a vacuum side opposite the seed side. The seed meter further includes a first housing portion surrounding a first portion of the seed disk in a fixed relationship to direct the supply of seeds against the seed disk and a second housing portion. The second housing portion is configured to move between a first position extending to a second portion of the seed disk to operate in concert with the first housing portion to direct the supply of seeds against the seed disk and a second position providing access to at least a portion of the second portion of the seed disk including the lowest most portion of the seed disk.
