I needed something to get my Lawn Tractor from the grass onto my back concrete patio. With a 5-in drop it was really ruining my mower deck everytime I tried to drive up. I considered building wood ramps, but was worried about rotting, and termites. I bought 2-Sets (4 Total) of these ramps and after leveling the ground, placed them side by side to make one nice long ramp about 78-in wide. I secured them to the ground with 1-ft long galvanised tent nails/spikes, two per ramp, eight total. Final Result: Big Difference, the ramps look great, they don't move at all, and the mower rides on/off the concrete without any problems. I can even drive my truck onto the patio without any difficulty. A little expensive but a great solution. TIP: open the delivery box outside, the ramps have a very, very strong rubber smell, it lasts for about 4-days and then goes away.
