Small tractor operated seed planter with battery drive consists of a frame, furrow openers, individual seed boxes and battery drive, vertical rotor type seed metering mechanism, push button switch, and speed regulator. Seed metering mechanism gets a drive from the dc motor with aids of chain and sprocket arrangement instead of from ground wheel. As per the design calculations, the width of seed planter was 1.25 m. Shoe type furrow openers were selected to open the furrow. No. of furrow openers and row to row spacing was 5no.s and 25 cm respectively. Length of simplex chain, the pitch of the chain and no. of links was 43 cm, 1.5 cm, and 29 respectively. No. of teeth on sprocket and gear ratio was 12 and 1:1 respectively. Capacity of the seed box was 1kg per one furrow, length, and diameter of the feeder shaft was 104 cm and 1.5 cm respectively, 12vDc motor was selected for operating the seed metering mechanism instead of a ground wheel. Speed of the dc motor was 100 rpm and regulator was selected for setting Dc motor speed according to tractor rear wheel speed in different gears. To avoid wastage of seed in turnings the push button switch was selected to disconnect the motor from the power supply. Small tractor operated seed planter with battery drive metering mechanism evaluated for its performance, results shown that the field capacity, field efficiency of the planter, fuel consumption, seed to seed spacing, depth of sowing and germination of seed was 0.30 ha/h, 66.17 %, 1.87 lit/h, 23.2cm, 5.4cm and 97 % respectively.
