I Loaded a Kubota 2601 tractor with a front loder & tiller attached on a trailer with these ramps.That is the main reason I bought the ramps. They work fine!
Awesome light weight and sturdy. The six foot length is helpful when loading low profile vehicles on my car trailer. My only complaint is that sanding of edge welds would get rid of the sharp points.
They are great. Very sturdy. They replaced the 4' ramps my trailer came with. They are smooth to drive up and down. They are lighter than the shorter steel ramps I had. I have recommended them already to my racing buddies.
