I got my garden tractor stuck in sloppy mud. So I took my jeep back to drag it out and got my jeep stuck in the slop. Ordered these on a Monday got them on Wednesday at 10am. By 10:30 my jeep and garden tractor were on firm ground. Seem to be very sturdy and they worked better than I expected. Both vehicles got immediate traction and had enough momentum to get to dryer ground.
