on appropriate rice post-harvest technologies or techniques. At each section, there are important point, information, knowledge and cautions for the rice grain processing, accompanied by a number of figures to illustrate the text in the handbook. Among several rice-producing techniques in PNG, the least developed technical area is post-harvest Vishwavidyalaya, Raipur. This machine made crop bundles of rice weighing about 5.3. The fuel consumption of machine was varied with crop type. It was found 1.22 and 1.15 lit/h with soybean and rice crop respectively. According the cost of operation of reaper - - binder machine also varied according to type of crop. It was found to be 860 and Design History In the 1980s, IRRI developed and introduced the IRRI-CAAMS reaper. This machine has a scissor-type cut- ting mechanism (cutterbar) similar to imported reapers, which are now gaining popularity in rice producing areas in Luzon. Some problems were encountered when the local design was introduced for commercialization. DESIGN PROCESS It is the systematic, Theoretical analysis of the methods applied to a study or to the theoretical analysis of the method and principles associated with branch of study. 1. Studying the present mechanisms. 2. Field Survey 3. To identifying the potential problem. 4. Problem definition. 5. Literature review. 6. Reaper and binder machine is manufactured by BCS Company. The physical construction is divided into three parts: steering mechanism, Engine mounting and cutting and binder mechanism. Fig. 1: Reaper and Binder machine Steering mechanism: In this machine, steering or direction controlling of machine is done by foot, so its foot propelled machine. Grain harvesting is the important part in agricultural mechanization. The use of reaper technology in developing countries to minimize the product cost which will be result in economic development of agricultural production. This paper tends to provide the design and development of manually or mechanically operated reaper machine. The following technical specifications of the machine were determined prior to field evaluation; overall dimensions and weight, power source, number of gears, details of cutting mechanism, steering mechanism, and safety arrangements.

This machine reduces the human effort as only human maize grown in small forms. effort is in pushing the reaper. Other cutting work is done 3. By result of field experiment in a very small field, by the blades automatically. Machine showed that the loss of harvesting is lower than 2. • Crop Cutting Machine which is available in market is very costly. We can make Crop Cutting Machine our self and we DESIGN AND FABRICATION OF CROP REAPER. [8] "Mechanization of agriculture - Indian scenario", Dr. S.D. in direct seeded rice culture . Australia Journal of Crop Science, 7:989-1002. [15]Hunt, D. 1973. Farm Power and Reaper machine is a harvesting tool which cut crop and windrow it on the field. The main components of reaper are header, power source an
