Prediction of Tractor CG by Considering the Safety Devices at Concept Level

Tractor weight transfer is the most common farm-related cause of fatalities nowadays. As in India it is getting mandatory for all safety devices across all HP ranges. Considering any changes in the weight from an attachment such as Rops, PTO device, tow hook and draw bar etc. can shift the center of gravity towards the weight. center of gravity is higher on a tractor because the tractor needs to be higher in order to complete operations over crops and rough terrain. Terrains, attachments, weights, and speeds can change the tractor’s resistance to turning over. This center of gravity placement disperses the weight so that 30 percent of the tractor’s weight is on the front axle and 70 percent is on the rear axle for two-wheel drive propelled tractors and it must remain within the tractor’s stability baseline for the tractor to remain in an upright position. In our present study formulating the prediction of tractor CG by using a modified excel spreadsheet package employing the parameters of the model, tractor CG were then determined. Finally, the effects of changes in the parameters of the model were evaluated and results of the analyses indicate the changing the tractor CG about the x-axes and y-axes have an influence on the weight distribution of the tractor from front and rear wheel, whereas increasing the tractor weight percentage on the front wheel have an benefit of tractor less lifting on the front end.
