Unlike in a conventional front loader, the lift arms in these machines are alongside the driver with the pivot points behind the driver's shoulders. Because of the operator's proximity to moving booms, early skid loaders were not as safe as conventional front loaders, particularly during entry and exit of the operator. Modern skid loaders have fully enclosed cabs and other features to protect the operator. Like other front loaders, it can push material from one location to another, carry material in its bucket or load material into a truck or trailer.
Skid-steer loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and where the left-side drive wheels can be driven independently of the right-side drive wheels. The wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. Turning is accomplished by differential steering, in which the left and right wheel pairs are operated at different speeds, and the machine turns by skidding or dragging its fixed-orientation wheels across the ground. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. As with tracked vehicles, the high ground friction produced by skid steers can rip up soft or fragile road surfaces. They can be converted to low ground friction by using specially designed wheels such as the Mecanum wheel. Skid-steer loaders are capable of zero-radius, "pirouette" turning, which makes them extremely maneuverable and valuable for applications that require a compact, agile loader. Skid-steer loaders are sometimes equipped with tracks instead of the wheels, and such a vehicle is known as a multi-terrain loader.
Knowing the tractor you want, and the market for it is a start, but it can all go out the window after a little hands-on time with the actual machine. It may have lived a hard life, and be worth half as much, or it may be a barn queen in mint condition and justifiably cost a pile more. For the rookie tractor buyer or the mechanically disinclined, this is where knowledgeable friends come into play.
Comfort is a prerequisite to look for when purchasing a tractor, since the vehicle is used by farmers to do strenuous work such as hauling. Comfortable tractors are furnished with various features and capabilities that make them easy to use and manage while effectively performing their farm operations. Tractors are custom made and ensure comfort so that operators can work for longer periods without straining. The larger the operator's property, the more a comfortable tractor is required. A comfortable tractor is also multifunctional as it can haul, dig, lift, and pull heavy things.
