I'm kinda asking this for a friend so my knowledge of this paticular tractor is limited.He has a 70's model Ford 6000 he wants to take to the scrapyard.Problem is he says it has some sort of safety mechanism and the back wheels will absolutely not turn if the motor isnt running.The motor is shot so he cant move it.He's tried to pull it on the trailer with his backhoe to no avail.He's to the point of paying a wreaker to haul it.But I thought there may be a way to disengage whatever prevents the wheels from spinning .I thought mabye somebody on here might know.
