Abstract
A seed level sensor for automatic seed planting apparatus is provided with connecting plugs for connecting the seed level sensor to electrical leads presently existing between a seed dispensing sensor and a seed planter monitor. The seed level sensor includes a switching device connected in one of the lines of the electrical leads between the seed dispensing sensor and the seed planter monitor and which interrupts the operation of the seed dispensing sensor when the level of seeds within the hopper is below a predetermined level. An indicator associated with the seed planter monitor is energized for a given period of time when seeds are below the predetermined level, to alert the operator that a low seed level exists in the hopper.
