College of Agriculture was established in 1965. Department of Agricultural Engineering was established in 1980 Department of Agricultural Engineering was established in 1980 We have 18 faculty members (power & machinery, Irrigation, Food processing, environment engineering) We have 18 faculty members (power & machinery, Irrigation, Food processing, environment engineering) Slide 3 25-5-20043 Introduction Implement Connection Slide 4 25-5-20044 Introduction Implement Connection Slide 5 25-5-20045 Tractor Jobs Off Road Tractor Performance: To get the most from the tractor. On Road Stability and Safety Slide 6 25-5-20046 Instrumented Tractor In 1994, we established an instrumented tractor. The tractor was improved during these 10 years. Slide 7 25-5-20047 Objective The objective of this project was to develop a microprocessor unit to measure a set of performance parameters of an instrumented tractor with mounted implements.
