The present invention is an improved grain drill and a method retrofitting a previously manufactured grain drill to provide accurate weight determination of seed in a seed hopper of the grain drill. A grain drill in accordance with the invention includes a frame having a plurality of wheels for supporting the grain drill during rolling over a surface of ground to be planted with seed grain; a hopper for containing the seed grain to be planted in the ground; a support which is joined to opposed sides of the frame and to spaced apart locations of the hopper to transfer weight of the hopper to the frame, the support including at least one weight sensing device which senses a weight of seed grain in the hopper transferred through the support to the frame and provides an output of the sensed weight of the seed grain in the hopper; and a display, coupled to the output, for displaying the weight of the seed grain contained in the hopper.
A seed planter comprising:
A method for modifying a seed planter including a frame having a plurality of wheels for supporting the seed planter during rolling over a surface of ground to be planted with seed, a container joined to the frame for containing seed to be planted, and a planting mechanism which plants seeds received from the container below the ground comprising:
A scale for use with a seed planter including a frame mounted on ground engaging wheels, a seed container for containing seed and being supported on the frame, a planting mechanism which plants the seeds contained in the container below the ground, the scale comprising at least one load cell that suspends the seed container from the frame, the at least one load cell being mounted so that an entire weight of the seed container and any seed therein is supported on the frame through the at least one load cell;
A scale for use with a seed planter having a frame mounted on ground engaging wheels, a seed container for containing seed and being supported on the frame, a planting mechanism which plants the seeds contained in the container below the ground, the scale comprising at least one load cell that suspends the seed container from the frame so that an entire weight of the seed container and any seed therein is supported on the frame through the at least one load cell, and a readout device operatively connected to the at least one load cell so that the weight of the seed container and any seed therein causes deflections of the at least one load cell which are translated into measurable weight of the seed in the container displayed on the readout device.
