I’ve seen plenty of Range Rovers and big 4 x 4s get stuck with totally the wrong tyres for soggy grass! Plus very few Chelsea tractors ever go off road for fear of getting the vehicle dirty !! 4 x 4 with correct tyres will always win over 2wd. BTW I’ve seen 4 motions stuck on fields trying to pull a 2000kg caravan up a gradient. No need for me to preach to the converted - going off road needs proper preparation and an understanding of the vehicle’s capabilities
