Well spotted spyderman! That's exactly what's happened... Except the traction is shocking once the hard surface runs out 100m or so before we got stuck!
Yeah we think the only way is thru the field...
Can you give me some more info?
1) Did you drive the lane in the same direction as in my picture, as in the stream in on your left?
2) Is he before or after the tree?
3) If he's before the tree anyone looking to recover him would have to reverse over that tree, even I haven't tried that. I'm not sure that would even be possible as there's a big bit of tree root that you drop off of on the way down, maybe with waffle boards. Reversing down with the drop behind you is certainly a sphincter moment.
4) How many wheels and which ones are off of the track and over the edge?
5) I'm thinking if it's just one or two N/S wheels, the answer would be to jack it up on a hi-lift and push it sideways off of the jack to hopefully get the wheels back on the track, might take a few goes, with waffles ideally to stop it slipping back.
6) The field IIRC is much higher up than the lane with a really steep bank. I'm not sure that a recovery from the field would be possible, unless there's a perfect gap in the trees and the bank isn't too steep.
7) Do not go into the field without permission.
