     Seed Planter


The basic requirements for small scale cropping machines are, they should be suitable for small farms, simple in design and technology and versatile for use in different farm operations. A manually operated template row planter was designed and developed to improve planting efficiency and reduce drudgery involved in manual planting method. Seed planting is also possible for different size of seed at variable depth and space between two seed. Also it increased seed planting, seed/fertilizer placement accuracies and it was made of durable and cheap material affordable for the small scale peasant farmers. The operating, adjusting and maintaining principles were made simple for effective handling by unskilled operators (farmers).


A planter is a farm implement, usually towed behind a tractor, that sows (plants) seeds in rows throughout a field. Planters lay the seeds down in precise manner along rows. Various machines meter out seeds for sowing in rows. The ones that handle larger seeds tend to be called planters, whereas the ones that handle smaller seeds tend to be called seed drills, grain drills, and seeders.

Under intensive cropping, timeliness of operations is one of the most important factors which can only be achieved if appropriate use of agricultural machines is advocated. Manual method of seed planting, results in low seed placement, spacing efficiencies and serious back ache for the farmer which limits the size of field that can be planted. To achieve the best performance from a seed planter, the above limits are to be optimized by proper design and selection of the components required on the machine to suit the needs of crops.

Seed Planter:

In a mechanical drive system the unit works by a small suspended tire being driven by another which is in contact with the ground (driven) tire. As the operator lowers the planter the two tires make contact and the planter is engaged. When the driven wheel begins to turn it then turns a series of gears that determine the population of the seed produced. The gears can be changed by the operator in order to change the planting population.

Purpose of seed planter machine:

The basic objective of sowing operation is to put the seed and fertilizer in rows at desired depth and seed to seed spacing, cover the seeds with soil and provide proper compaction over the seed. The recommended seed to seed spacing and depth of seed placement vary from crop to crop and for different ago-climate conditions to achieve optimum yields.


When power supply is given to the Dc motor through solar panel it starts rotating at a finite speed. It also tends the shafts and the gears to rotate at that finite speed as well. The another Dc motor motor which is connected with the transport wheels is for the moving purpose of the project. The furrow opener is attached with the shafts and the seed container. It is used to make furrow far making space for the seeds to plant. As the furrow opener digs the soil for making space for  the seeds, simultaneously seeds go down through the seeds container into the lane made by the furrow opener. The furrow opener is attached with the circuitry of the shafts and gears. It works according the movement of the gears and the shafts.

    Advantages of machine :

    • Following are the advantages of manual seed planter machine are

    • Improvement in planting efficiency.

    • Increase in crop yield and cropping reliability.

    • Increase in cropping frequency.

    • It increased seed planting.

    • Seed/fertilizer placement accuracies.

    • It was made of durable and cheap material affordable for the small scale peasant farmers.

    • Lesser maintenance cost. The seed can be placed at any required depth.

    • The plant germination can be improved.

    • Requirement of labor also decreased. It consume less time for sowing.

    • Seed can be placed uniformly in a row with required distance between plants.

    • Provide proper compaction over the seed.


    This manual seed planter machine has considerable potential to greatly increase productivity. Other countries of the world where the two wheel tractor is the main traction unit in farming. The main task now is to promote this technology and have available to farmers at an affordable price. The manual Seed Planter machine can be readily made from local components in workshops. The only specialized items required are the seed meters plunger which can be sourced at an inexpensive price from local promoter and plunger is easily manufactured. By using of this machine, achievement of flexibility of distance and depth variation for different seed plantation is possible.
