- Abstract
Based on the output of software made in Visual Basic, an electromechanical implement lift system with position control was developed to maximize useful power of a low horse power (hp) tractor by replacing hydraulic system requiring higher power. It comprised of two lower links, one top link, two lift rods, one connecting rod and a power screw mechanism. The prototype was tested as per IS: 12224-1987 for recommended load of 150 kg on test frame and satisfactory results were found. The response time for lifting a load of maximum lifting capacity on test frame i.e. 116 kg and 110 kg for entire lifting range was found to be 71 s and 20.7 s for single start screw and triple start screw, respectively as compared to 44.7 s and 13.3 s for lowering the loads. The position control of the system was also tested and found satisfactory with no drop in the height for maximum lifting capacity. The developed system could save 88% of tractor input power compared to hydraulic system.
