While they can be frustrating when you're trying to get somewhere in a hurry and your bus is stuck behind one, they are pretty cool looking. Most have all their moving parts (including the engine) exposed, and they look like something out of a movie about a post-apocalyptic future. I went for a walk the other day to take pictures of tractors, and all of the following pictures are of tractors that I found on one short stretch of road. There are a much greater variety of tractors than these, and I still occasionally see new varieties of tractor.
This is the most popular kind of tractor on the roads around here. I'd estimate that 85% or so of tractors around here are this kind.
When people are going to the field, or students are coming to school, they'll just all ride standing up in the back of one of these.
This is the second most popular kind of tractor. It's more powerful and bigger, so you see these hauling bigger loads.
This is my favorite kind of tractor.
Another awesome tractor, clearly inferior to the last one because it doesn't have a sun roof.
And yet another type of tractor!
This isn't a tractor, but people drive these a lot too. They're three wheeled motorcycles (I want to call them tricycles, but that sounds weird) so you can put loads in the back. Most of the 'taxis' in the nearby big city are these, so you just hop in the back of one of these that's set up for people, and they'll take you wherever you want.
