I like that these were affordable, light weight, and longer than my existing ramps. However, the thin cross bars bent when loading my compact tractor on my trailer. The tractor weighs 3,000 lbs. With implements it may be 4,500 lbs. It is a little hard to see in the photos but nearly every one of the cross bars bent under the weight. I may use these to load my motorcycle but do not trust them to load my tractor or a car/truck.
