High moisture content of wetland soil makes wheeled farm vehicles have to struggle with severe loss of their mobility. Farm machinery are prone to being bogged down and traffic-ability of the soil surface layer is very poor, when working on problematic soil or soft soil area with low load-bearing capacity. This is due to hard pan damage or zero hard pan to support the machines, resulting in the machines not having sufficient traction and ability to float. A traction aid fitted to the wheels of a prime mover is needed to improve ground traction and its ability to maneuver on soft soil. Farm vehicles that are operated in these conditions require a traction aid fitted to the wheel or in place of wheel is needed to improve ground traction and its ability to maneuver on soft soil. The main purposes of this study are to examine soil behavior under traction aid device attached on the farm machinery wheel. As per the studies conducted earlier, Mobile Traction Aid for Farm Machinery (Mo-Traid) that have been develop are found to be the most effective device for wet rice fields to support and help the farm machinery when it encounter soft soil area. Mo-Traid made by mild-steel with size 30cm x 10cm x 7cm. This equipment can be adjustable with maximum length is 45cm. The weight of this equipment is 5kg and it practical to be carry to the field. From the research it was revealed that the Mo-Traid exert more pull in comparison with tires in flooded soil conditions.
