Skid-steer loaders are sometimes equipped with tracks instead of the wheels, and such a vehicle is known as a compact track loader. They can be converted to low ground friction by using specially designed wheels such as the Mecanum wheel. As with tracked vehicles, the high ground friction produced by skid steers can rip up soft or fragile road surfaces. The extremely rigid frame and strong wheel bearings prevent the torsional forces caused by this dragging motion from damaging the machine. Construction sites and their business contract requirements often call for landscapers to have operational skid steer reverse signal alarms and beacon lights. Use and continued maintenance of these alarms greatly reduce the risk of incidents involving running over and/or pinning co-workers between the machine and an obstacle. These alarms are not always standard equipment on all farm or landscape skid steer machines, depending on factors like the age of the machine. For youth hired to work in agriculture, it is recommended they be at least 16 years old and have an adult assess their abilities using the Agricultural Youth Work Guidelines before being allowed to operate a skid steer.Īnother thing to consider are beacon lights and reverse signal alarms that offer a warning to co-workers about the skid steer’s movements. In the US, it is illegal for youth under age 18 employed in non-agricultural jobs to operate a skid steer. Before allowing anyone, including adults, to operate a skid steer, they should be assessed on their ability to safely operate the machine and trained in its safe operation. The differential steering, zero-turn capabilities and lack of visibility often exacerbated by carrying loads with these machines means that their safe operation requires the operator have a good field of vision, good hand eye coordination, manual dexterity and the ability to remember and perform multiple actions at once. This "zero-turn" capability (the machine can turn around within its own length) makes them extremely maneuverable and valuable for applications that require a compact, powerful and agile loader or tool carrier in confined-space work areas. Skid-steer loaders are capable of zero-radius turning, by driving one set of wheels forward while simultaneously driving the opposite set of wheels in reverse. 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 wheels typically have no separate steering mechanism and hold a fixed straight alignment on the body of the machine. Virtually all modern skid steers designed and built since the mid-1970s use two separate hydrostatic transmissions (one for the left side and one for the right side). Earliest versions of skid steer loaders used forward and reverse clutch drives. This is accomplished by having two separate and independent transmissions one for the left side wheels and one for the right side wheels. Skid-steer loaders are typically four-wheeled or tracked vehicles with the front and back wheels on each side mechanically linked together to turn at the same speed, and where the left-side drive wheels can be driven independently of the right-side drive wheels.
