I got stuck this evening, took a bit of jacking, both waffle boards have now been christened, in fact they are both still wedged into the ruts, as I couldn't get them out. I tried using the hi-lift to jack them out, but it was so full of mud it gave up.
I'm going back in the morning with jai, to rescue them and have another go at the lane. It all looked good, until I turned the corner and sunk. It might be OK once it's been driven a bit, but at the moment it's pretty impassable, I think the farmer has been driving it in his tractor again. The tops of the ruts need smoothing off.
Don't try it guys, certainly not alone anyway.
Will take some pictures tomorrow.
