India is said to be an agricultural base country directly or indirectly 75% of the peoples are dependent on farming, in this agriculture sector there is a lot of field work, such as weeding, reaping, sowing etc. Apart from these operations, spraying is also an important operation to be performed by the farmer to protect the cultivated crops from insects, pests, fungi and diseases for which various insecticides, pesticides, fungicides and nutrients are sprayed on crops for protection. In today?s world, one use many different spraying technologies using energies like electrical energy, solar energy, and chemical energy of fuels. This fact makes one know that how large amount of energy is getting used at such place where mechanical energy can be used instead of direct energy sources. Farmers are facing enormous problem while spraying the pesticide like tank capacity is very small, high cost and spaying time taken more. In order to reduce problems different type of sprayers has been introduced in the market, but these devices do not meet the specified problems or demands of the farmers. To solve these difficulties a new equipment that is mechanically operated wheel driven sprayer, it is a portable device and does not need any fuel to operate, which is easy to move and spray the pesticide by moving the wheel is to be developed. This wheel operated pesticide spray equipment consumes less time and achieves uniform nozzle pressure; crank mechanism with piston pump which is driven by the wheel is also used. The main aim of the paper is to be develop a low cost mechanically operated sprayer pump for Indian middle scale farmers. The device has been validated with the user group and got good feedback from the user
