These Steiger monster tractors come with a choice of either 4 wheel drive or “quads” which are more like three smaller metal wheels wrapped by a very strong belt with a tread, so the tractor operates almost like a caterpillar, or other larger road-building machinery.
Not being a farmer I can only assume that these quad treads can keep a tractor from getting stuck in muddy sloughs and hollows in their fields, where tires would usually just spin and spin. A farmer likely keeps the types of fields he has to work in mind when buying a new tractor.
Tractors sure have come a long, l-o-n-g way in just one lifetime, right?
If you are retired, you can probably line up a row of model tractors to represent the various types you have worked with over the decades. Maybe this STX450 Case International Harvester AccuSteer with a 3-point-hitch and PTO was your favourite. This particular model is unboxed, but perfectly clean and new in every aspect. You might just want to put it where you can eye it every day, and relive you best memories of working with it. You can have this one – the only one of this model I have, for $14.00 Cdn.
