I waited. “8-5, in the back, can I get 8-5?” I raised my card. “9, 9, can I get 9?” Overalls was on the ropes. “8-7-5, $8,750, what do you say? Nice Kubota. Very nice Kubota. 8-7-5.” Overalls bid, that son of a gun. “9, can I get a –” I shot my card up. “$9,500, up front, what do you say?” Overalls was shaking his head no. “With the backhoe, a great deal at 9-5, 9-5,” Overalls kept shaking no. He was out. “In the back, $9,000, going once, going twice, SOLD!”
A tractor is a large, heavy duty vehicle with a petrol or diesel motor delivering high torque at a low speed. Tractors are especially indispensable in the world of agriculture, as they can tow implement or machine attachments used for ploughing, tilling, harrowing, planting and feeding, as well as spraying fertilizers and pesticides. Another popular attachment is the hey tedder that allows haymaking. Tractors also have the power to haul large items, and the heavy treads of their rear tyres allow plenty of traction on soft or uneven terrain. The more modern RC tractors can be controlled remotely and some are used to mow like a tractor mower.
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.
Compact tractors are just like other tractors in that they can be used with a variety of different attachments that have various purposes in agricultural and construction situations. Unlike other tractors, however, compact tractors weigh under 4,000 pounds, and they use less than 40 HP, with many using only 20 HP to 30 HP. These specialized tractors run at less than 540 RPM, and they are easier to store and maneuver than traditional tractors.
The conventional bucket of many skid loaders can be replaced with a variety of specialized buckets or attachments, many powered by the loader's hydraulic system. These include backhoe, hydraulic breaker, pallet forks, angle broom, sweeper, auger, mower, snow blower, stump grinder, tree spade, trencher, dumping hopper, pavement miller, ripper, tillers, grapple, tilt, roller, snow blade, wheel saw, cement mixer, and wood chipper machine.
Before the 1990s, all excavators had a long or conventional counterweight that hung off the rear of the machine to provide more digging force and lifting capacity. This became a nuisance when working in confined areas. In 1993 Yanmar launched the world's first Zero Tail Swing excavator, which allows the counterweight to stay inside the width of the tracks as it slews, thus being safer and more user friendly when used in a confined space. This type of machine is now widely used throughout the world.
The make and model category is further divided into the purpose in which a driver sits on the machine and drives it, and the other where the operator works alongside the vehicle. The type of drive is further broken down to wheel type and track type. The wheel type is then broken down into two, three, and four-wheel types of drives, while the track type is subdivided into full and half-track types of drives.
