If you don't want to shovel much but still get unstuck out of just about anything, from my research here's the top rated portable solution out there ... made in Austrailia, super tough, and from everything I have read about them - THEY WORK (not cheap though, but neither is each extraction by a Caterpillar): https://www.amazon.com/Maxtrax-MKII-MKIIs/dp/B00HYCVSW6
I bought a set similar to what you posted after getting my tow car stuck in sugar sand, they are about 8 in wide and 2.5 ft long made out of orange thermoplastic material. They were under $20.
