Unit D34+4: J&M 812X Grain Cart w 1050 Singles + NH T8.380 LSW Singles Row Crop Tractor

Compaction test results measured at 2019 Dundas SCIA event
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. […]
Plot Comments Although a much lighter machine than the tracked skid steer there is much high soil stress both with and without the bale. […]
Plot Comments This a light machine so stress is low. When the bale is carried you can see the shift of pressure to the front rollers on the track represented in the plot. […]
Plot Comments These plots show the benefit of a CTIS system installed on a forage harvester. The harvester has a heavy front axle load and the high pressure tires can be lowered in the field to reduce the stress in the topsoil. […]
Plot Comments Large tires at a moderate pressure again show lower stress in the upper soil. Heavy weight is apparent with the stress at 20 inch depth. […]
Plot Comments This combine showed very high surface stress. Very similar to the D16 plot. Most of the weight is carried by the mid rollers of the track unit. […]
