Knapsack sprayer consists of a pump and a air chamber permanently installed in a 9 to 22.5 liters tank. The handle of the pump extending over the shoulder or under the arm of operator makes it possible to pump with one hand and spray with the other. It has a spray lance fitted with nozzle and has two straps for mounting the sprayer at the back of the operator. Uniform pressure can be maintained by keeping the pump in continuous operation.

It consists of a frame on which a high density polyethylene tank, fuel tank, engine, delivery pipe, shock proof cushion, and a spray hose. The pump adopts horizontal gear driving. It is powerful and stable in pressure. It adopts double cylinder pump, which raises operational efficiency. The piston is heat treated and wear resistant. 'V' packing adopts special materials so it is durable. The engine has electronic ignition, which is easy to be operated and maintained. Its engine has high power to weight ratio. It uses gasoline as a fuel and produces one power stroke for each 1800 of crank rotation. Pressure is controlled by oil valve; spraying pressure is changeable freely and up to 30 kgf/cm2. Its structure is rigid; materials are excellent and easy to be maintained. It can also be used for dusting and ULV application.

The sprayers essentially consists of a tank which is made of fibre glass or plastic, pump assembly, suction pipe with strainer, pressure gauges pressure regulators, air chamber, delivery pipe, spray boom fitted with nozzles. These are hydraulic energy sprayers. They utilize PTO power of the tractor to operate the pump of the sprayer. Basically the spray boom can be arranged in two ways; ground spray boom and overhead spray boom. The overhead spray boom is designed for tall field crops and the planting is done in such a way that it leaves an unplanted strip of about 2.5 m width for operation of the tractor. Therefore a planted strip may be 18-20 m wide and after every planted strip a fallow strip has to be left for tractor operation. For ground spray boom the planting has to be done in rows keeping in view track width of the tractor. It is suitable for use when the crop height is small. The complete sprayer is mounted on 3-point linkages of the tractor.

The machine consists of tank of 400 litres capacity, pump, fan, control valve, filling unit, spout adjustable handle, pressure regulator and spraying nozzles to release the pesticide solution in to stream of air blast produced by the centrifugal blower. The air blast distributes chemical in the form of very fine particles throughout its swath, which is on one side of tractor. The major portion of swath is taken care of by the main blast through the main spout and the auxiliary nozzles cover the swath area near the tractor. The sprayer is mounted on the tractor 3-point linkage and is operated by tractor PTO. The orientation of air outlet can be adjusted for its direction and width of coverage.
