A power tiller operated bed former/ridger was developed in FMPE Division of BARI, The bed former consists of two-moldboard type ridger and a V-shaped planner. The machine is suitable fur funning beds and channels, alternately, the beds art: suitable for planting crops like potato, maize. wheat, sugarcane and even rice, The bed and furrow system is suitable for efficient management of irrigation. The width and depth of the bed tanner arc adjustable. The machine was operated by a 12 hp power tiller. The field capacity of the machine was 0.14 ha/h at a speed of 2 km/h. The preliminary test result of the machine was satisfactory.

Farm Mechanization
1. To design and fabrication of bed former for ridging up bed
2. To test the bed former for potato, maize and wheat
A prototype of power tiller operated bed former/ridger was fabricated in the FMPE Divisional workshop. The local materials like M.S, angle bar, M.S. flat bar, M.S. rod, M.S. sheet, nut-bolts, etc were used to fabricate the bed former. The functional parts of the bed former are: a) frame, b) bed forming ridger and c) planner/ compactor. After fabrication of the prototype, it was tested in the divisional experimental plot to observe the field performance. During the test, it was observed that the furrows were not enough straight. This was probably due to the unskilled driver. However, more information through intensive field test of the machine was be collected and the machine was modified/improved accordingly.
Research Report
Bed former had a field capacity of 0.14 ha/h at a speed of 2.0 km/h. This capacity may vary with the variations in row spacing required by different crops. Field efficiency was found 54%. The bed former can be used as multicrop implement for growing potato, maize, wheat and pulses. It seems there is good scope of work for the bed former/ridger in future.
