Im no good at putting up links to you tube. But if you go on and type in Persistant digger driver. It brings up a video of sum gabshite tryna load a mini digger onto a trailer behind a jeep with a broken ramp. Its well worth a watch, althow it didnt make me cringe as much as john/k video with the dozer towing the digger. specily when the chin went slack and she rocked back again. Think it was one of those (brown trouser) situations.
Edit Think i mite have just taught mysel how to do it. if the link below works then were hot to trott. if not then im sorri but at i tryd my best.
