I don't know if there is something I'm missing but you push the 4x4 switch and thats it right? Because that sure didn't work for me.
Was checking on some irrigation after a heavy rain with my 7 year old daughter and we got stuck. Pushed the 4x4 switch and... nothing. Front tires never moved an inch. Tried the transfer lock and nothing different. I tried forward, reverse, high and low and those front wheels never turned at all.
I was already upset that this JD is a underpowered expensive piece of garbage but now this is just too much. We had to walk a mile in the mud to get a tractor to pull it out.
I absolutely abhor this machine
