Unit D40: Class 750T Tracked Combine with CTIS

Datasheets that detail the results of soil compaction testing at SCIA events.
Plot Comments This is a good example of the baler being a lighter machine than the tractor, but having a higher stress in the topsoil due to the tire configuration. […]
Plot Comments Heavy axle weight and a narrow tire even with moderate tire pressure creates a relatively high soil stress. […]
Plot Comments From the soil perspective, the anhydrous tank and the pickup truck are very similar. […]
Plot Comments This plot shows that even at a reasonable 26psi, a bias ply tire with a round profile can put high stress in the topsoil. […]
Plot Comments These plots show two types of tires. The plot D29_R_1 shows a slight reduction in stress with a slightly larger tire. Stress at 20 inches was comparable. […]
Plot Comments This wagon had some issues tracking straight so that both front and rear tires went over the sensors. […]
Plot Comments Very high topsoil stress under grain wagon tires. This was true for all tire types. Notice the strange weight distribution of the wagon. […]
Plot Comments The left two plots show the increase in pressure when weight is added to the vehicle. The right plot is again with weight in the vehicle at a difference sensor installation. […]
Plot Comments The first plot is the right side rear tire. The second plot is the front tire as it drove over and the reversed over the sensor to avoid the measurement equipment. […]
Plot Comments These plots again show high pressure in the topsoil from high pressure tires. Notice the weight distribution when the boom is folded in. […]
