Unit D31: Nuhn Quad-Steer 17000 Liquid Manure Spreader + Class Xeron 4500 Tractor
Plot Comments Similar results to other CTIS systems. Comparing the high pressure tires to the low pressure tires shows reduction of stress at 6 and 12 inches. The heavy weight still creates high stress at 20 inches regardless of pressure. […]
Unit E6: John Deere 7230R + Unverferth 7200 Grain Buggy with 30.5L-32 vs 900/60 R32
Plot Comments This unit compares two common tires for a grain cart a 30.5L-32 bias tire and a much wider 900/60 R 32 radial. The bias tire is associated with the plots titled E6_L_1 and E6_L_2. The bias tire had a higher inflation pressure with approximately the same load. Plots named E6_L_1 and E6_R_1 had some issues […]
Unit E5: JD 9460R + J&M 1050 Grain Buggy with Offset Tandems 650/65 R42
Plot Comments This vehicle compared high inflation pressure and low inflation pressure for the grain cart. Notice also the high inflation tire was ~3000 lbs. heavier. Notice the last peak on the plots is slightly higher for the plots names E5_1 and E5_2. Also notice the much higher overall response for the plots for the […]
Unit 4 + 31: Challenger M775E Row Crop Tracked Tractor and Tracked Brent Avalanche 1594 Grain Buggy
Plot Comments This unit tested the grain cart tracks the first two plots were aligned over the center of the track face which shows a lower soil pressure. The second two plots show the pressure under the outside third of the track face, directly under the track rollers. These plots did not record the track of the tractor since […]
Unit E2: Lexion 740 T Combine
Plot Comments This is an example of the variation in soil stress across the face of the Tire tread. The plots where the vehicle was off center show a higher soil stress directly under the rollers of the track unit. When comparing this unit with E47 you would expect and similar profile with a slightly lower soil pressure […]
Unit 1: John Deere 4940 SP Sprayer with VF 420/95 R50 and CTIS
Plot Comments The lower tire pressure reduced the stress at the 6 and 12 inch depths effectively. The weight of the vehicle means that the stress at the 20 inch depth is not as effectively reduced by lowering the tire pressure. Lowering the axle weight would reduce the stress at the 20 inch depth. The […]
Unit D47: Massy Ferguson 5713S Row Crop Loader Tractor
Unit D46: Massy Ferguson 5711 Row Crop Loader Tractor w 380’s
Unit D45+D7: Demco 750 Dualed Grain Cart w 650s + NH T7.260 Dualed Rear Row Crop Tractor w 480s
Unit D44: Hew Holland Backhoe LB75.B
Plot Comments The front a rear tires were somewhat misaligned. So each plot shows the peak of the tires individually. […]
Unit D43: Kubota RTV 900XT
Plot Comments This is a good example of a light vehicle only causing stress in the topsoil, however due to the weight and small tire size it is almost comparable to a pickup truck. […]
Unit D42+D8: Flat Rack Hay Wagon w 425s Singles
Plot Comments Although a large tire. Very high tire pressure causing high top soil stress. […]
Unit D41+D8: Loaded FlatRack Hay Wagon Tandem Rear w 12.5Ls + NH TS115A Singled Row Crop Tractor
Plot Comments Again, A wagon, similar to the gravity wagons. High pressure bias ply tires creating high soil stress. The tractor in this instance was not measured. […]
