I had to shift something like the iron stove once with only a rope & me.

I got the stove lined up widthwise with the slope & wound the rope around the stove so the free end was actually coming out over the top of it.
I then pulled like the guy above & the rope tumbled the stove over to its next up side & a bit up the hill.
Kept doing that untill I could get it to where I wanted.



I think the rope in, this position, acted as a lever & the slope wasn't too bad.
In a similar way I could turn a vehicle over, if the leverage isn't enough I'd add a pole or something & still use the rope.
A bloody tough way to do it, but thats why I got the job, no one else could do it.

When shifting whiteware around a huge pile of it, I & a friend have seen stuff roll uphill!
Its all to do with the 'centre of balance'. But when you actually see it happen.....
