Longitudinal wheel slip in off-road vehicles negatively impacts tractor traction, leading to power loss, decreased productivity, increased fuel consumption, and accelerated tire wear. By monitoring slip values, drivers can adjust acceleration to optimize vehicle performance, enhancing productivity and mobility. This paper presents the implementation of a microcontroller-based embedded system in 2WD tractors to measure and monitor slip ratio for the driver. Both actual and theoretical tractor speeds were recorded, with results displayed on LCD screens. A warning system alerted the driver when the slip ratio exceeded permissible limits. Field tests were conducted on various terrains (asphalt and sand) at a speed of 15 km/h using different loads (0, 2000, and 4000 N) and varying tire inflation pressures (15/20, 25/30, and 30/40 PSI for rear/front tires). Results on asphalt showed that slip ratio increased from 1% to 5% with higher tire pressure under no external load, and from 0% to 2% at loads of 2000 N and 4000 N. On sand, slip ratio rose from 6% to 10% with no load and from 5% to 8% at the same load levels. A maximum variation of 4% was observed between the measured and indicated speeds from the front sensor and GPS module.
