Sorry, I fat fingered that last post, and it submitted before I had a chance to complete the explanation.
Skip = Dumpster in British English
Skid = Pallet
Skid Steer = Type of steering on Bulldozers and Bobcats (Muddy's pic)
Skip Loaders are large industrial tractors that may not have a 3 point. (Dynahoe without the hoe)
Utility Tractor - lower version of Farm tractor.
McCormick-Deering W-4 or International I-4 = Utility tractor, lower to ground.
Farmall H = Same tractor, but higher. Row Crop Tractor. more ground clearance but more prone to tip over.
Neither of these have 3 point hitch. Just mentioning to illustrate the height difference between a utility tractor and a farm/row crop tractor.
