Self-Propelled Multi-Purpose Power Unit Design, Development and Analysis

The project was undertaken to develop a self-propelled multipurpose power unit suitable for small farmers. The prime mower is powered by a 5hp diesel engine. The V-belt drive is provided for the transmission of power from the engine to the traction wheels. An adjustable accelerator wire is connected to the governor for adjusting the engine speed according to the requirement. The worm gear reduction unit is located at the axle having a speed reduction ratio of 20:1. A telescopic type frame is provided which also supported the end of the output shaft with the help of bearing housing. The handle is modified so as to vary the height from 1.0 to 1.3 m from the ground. The developed multipurpose power unit is a versatile power unit that can be used for field preparation, sowing, and intercultural operation on front output shaft operations like Inter culture operation, water pumping, grass cutting & harvesting, and winnowing/threshing in small agricultural fields. 5hp self-propelled power unit developed under the project is a low-cost power unit which can efficiently be used for various tractive and stationary work and such power unit is found to be a useful for small and medium farmers.
