Hi Lynn,
we're running a used goldoni 2-wheel tractor, and it's mostly fun. I was lucky to get one from an agricultural trader (for1400£) and it was properly serviced and checked. Must be easier (and cheaper?) to ryan-air to Italy and get one there - but I couldn't be bothered. For transporting stuff, I got me a pre-loved motorbike trailer for free and found a tractor repair place that could weld on a hitch that fits to the bar on the goldoni. Almost perfect. The only attachment I have so far is a finger-bar that looks very impressive but needs a lot of tl&c (OK, the area that I mow is very hilly, scottish, uneven and I'm constantly hitting rocks) - so it's annually off to expensive service and repair (you'll find specialists at your local agriculture show). Oh, and we have a chain harrow, which works well behind the 2-wheel tractor. Pulling capacity for the goldoni is less of an issue - it's got a lot of ooomph (8HP), but even with the differential disengaged the wheels tend to spin when the going gets tough.
Good luck!
