The trailer looks to have removable sections under where the wheels fit and either the neck or axles of the trailer detach so there is very little, if any, jacking involved.Stupid question maybe!! Is there an easy way of lifting them on the trailer to fit the wheels or is it a jack and a load of wooden blocks affair!!! I used to sort out a lot of new machines few years ago that came on slave wheels or on pallets etc!! Worst ones were twin rotor rakes on slaves!! No matter where you put the slings they would wobble and sway but at least you knew they weren't going far!!! Round balers were easy, pick them up with the Hiab, tractors not so easy!!!
