I would add a screw type log splitter as very desirable if you burn wood at home and have trees you can use as a source of fuel. They work with a conical plug on the pto which has a screw thread cut on the cone which forces itself into the log. Here is a web site that might be of interest:-
http://www.hycrack.co.uk/log-splitter.htmI agree that the transporter box is useful. I have a set of bars which fit onto the edge of the box extending backwards which helps you pick up stuff like brambles and tree branches. I have made a plywood box about 4ft X 3ft which rests on the bars when I want to transport bulky stuff like straw bales or bags of fertiliser.
My Goldoni tractor and the transporter box came from:-
http://www.bsgtractorsandmachinery.co.uk/who are located at Marks Tey between Chelmsford and Colchester.
They also supplied a chain harrow and disk harrow. My land is on very light soil and the disk harrow works well for preparing seed beds or clearing weeds when the soil is damp but not when dry. But it is very heavy. The 4 ft chain harrow has been of little value until I added a 4ft length of 3inch angle iron as a weight on the back end to hold down. Adding a second 4 ft chain harrow behind the first might have a similar effect but on its own a single one doesn't seem to do much. Perhaps I am not using it right.
I also got a small pump which also fits on the pto and is prevented from rotating by a short chain clipped onto the 3 point linkage. I haven't used it but it wasn't expensive and could be handy if you want to drain a pond or set up a small irrigation system.
Good luck with your choice of equipment.
