As the world population increases more than ever before and increasing demand on food, feed and fiber, and security, the number of off-the-road vehicles is rapidly increasing for agriculture, forestry, military, mining and construction industries. Many researchers have studied and still investigating traction as it relates off-road vehicles and publications abound especially from developed countries of Europe, America and others. In our generation scientists are trying to put robotic vehicles on the lunar and Martian terrains. This trend makes the study of soil dynamics in traction a sine qua non in our tertiary and research institutions. In Nigeria there is a dearth of publications in this specialized area of study. This is a review paper and the purpose is to highlight some of the studies that have been conducted over the years, with a view to enlightening, encouraging, stimulating and challenging would be researchers. Trends in the development of soil bin with single wheel testers were reviewed including tractive and transport devices used in them. Traction parameters including motion resistance, measurement and data acquisition systems, traction predictive equations including wheel numeric and mobility numbers were also reviewed. Efforts made in the development of soil bin for soil dynamics research and further research interest at the Federal University of Technology, Akure (FUTA) were highlighted.

“…Rolling resistance as an important parameter affecting vehicle mobility has a significant role in the optimization of fuel consumption [2]. A well-documented study in the literature indicated that about 20e55% of the energy developed to the drive tractor wheels is wasted in the tireesoil interaction [3]. This is an alerting statistic to reveal the importance of energy dissipation within the realm of Terramechanics.…”

“…Due to the physical discomfort and awareness of health risk associated with granular fertilizer and pesticide application such as operators' hazard when having direct contact of chemicals during field operation (Juste et al, 1990;Matthews, 2000). Nowadays, there has been a growing concern about the environmental problems (such as air and water pollution and decline in biodiversity) associated with the application of mineral fertilizer and pesticides (Matthews, 2000;Yahya et al, 2007;Snow and Ghaly 2008). For these reasons, accurate and uniform application of fertilizer/pesticides is absolutely important in minimizing environmental problems and costs.…”

“…Over-doses can harm the environment seriously, as well as the crop itself. Consequently, the application methods of fertilizer/pesticides and the uniformity of the spread pattern have become important research topics in agricultural engineering (Yahya et al, 2007;Mohammadi, 2006;Ramesh and Shanmugan, 2011). A lot of effort on the influence of machine characteristics on the spread pattern has been done by Olieslagers et al (1996).…”

Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive operations such as water pumping, land preparations, transplanting seedlings, harvestings and threshing are being mechanized but other operations like fertilizer and chemical (pesticides) applications are not yet fully mechanized, rather they are performed manually with motorized backpack knapsack sprayers which have many disadvantages. The main objective of this study was to develop and evaluate a new concept dual-purpose chemical applicator for paddy fields farmers in order to complement the labor shortage during the peak period. Approach: A dual-purpose chemical applicator for flooded paddy field was evaluated using the S341.4 Standard in respect to the distribution patterns/droplet sizes and uniformity of spreading/spraying for the chemical application to boost agricultural mechanization in rice production and also to overcome the safety concern of hazardous spray drift during chemical application by the paddy farmers. The dual purpose applicator was mounted on a high clearance prime mover. The machine performances for both granular and liquid chemical application were reported. Results: Results for urea granular chemical indicate that at low (40 kg ha ) rates and 550 rpm disc speed distribution pattern skewed to the left whereas the distribution pattern shape at medium (80 kg ha ) and 1000 rpm disc speed, mean distribution pattern became poor (M-shape) and also at low and medium application rates the distribution pattern shapes lopsided to the left. For NASA glyphosate liquid chemical herbicide, the average values of (VDM) and (NMD) were 108 and 79 µm at 80 lt/ha application rate and 5000 rpm rotary disc speed and 185 and 119 µm at 80 lt/ha application rate 3000 rpm rotary disc speed. Conclusion: The experimental results from the experimental tests suggest that the average effective field capacity for the equipment with a prime mover was found to be 0.89 ha h −1 or 7.12 ha/man-day for an 8 h working day.
