It's in the back of the truck right now because I used it to scrape the rocks off the concrete bridge that the grader left behind. Big sharp rocks sitting on concrete will push right through a tire and the hole is too big to plug and sometimes too big to patch. I'm not the only one here that ruined a new tire from a chunk of gravel puncturing it.
Anyway, good for scraping rocks out of the back of a truck/trailer. Not real fast but there's no lifting aside from the weight of the scraper/placer and they're light.
I did use cardboard when I moved the slate slabs to the new place - slick enough I could slide the slabs. I actually slipped on the cardboard on the ramp & fell (ouch!) so I only put it down when I was ready to slide the slab down the ramp.
On my last trip to the old house, I got into dad's scrap lumber pile & pulled out enough usable plywood to make panels (cut to fit) for the sides of the trailer that are metal grating. Now I don't have to worry about mulch or gravel leaking out the sides - using the tarp was a 'pain'.
BTW, notice the springs on each side of the trailer ramp. My brother put them on his trailer & added them to mine (youtube idea, I think). I believe they are garage door springs. They are a HUGE back saver - the ramp is very heavy & dangerous when lowering it without the springs. No way I could have put that ramp up/down as much as I did moving everything I moved (all but the heavy furniture, 13,000 miles worth of trips).
