Abstract

A microcontroller based digital display unit was developed for 2WD agricultural tractors to measure and display the weight transfer from tractor front axle. The device includes a transducer for measuring the tractor front end reaction, an amplifier to amplify the transducer signal and a microcontroller to calculate and display the weight transfer from the front axle. The developed device can be mounted on any make and model of 2WD tractor. The digital display unit was rigorously tested in the laboratory as well as in the field. A maximum of + 3.5% variation in weight transfer was observed between the theoretically calculated and experimentally observed values.

Key words: Microcontroller, weight transfer, ring transducer, tractor, front axle.
