Modern hydraulic excavators come in a wide variety of sizes. The smaller ones are called mini or compact excavators.[7] For example, Caterpillar's smallest mini-excavator weighs 2,060 pounds (930 kg) and has 13 hp; their largest model is the largest excavator available (a record previously held by the Orenstein & Koppel RH400), the CAT 6090, which weighs in excess of 2,160,510 pounds (979,990 kg), has 4500 hp, and a bucket as large as 52.0 m³.
Buying a used tractor can save you a lot of money. Tractors are built to last many years therefore second-hand tractors may go through a few owners throughout their lifespan. Many farmers are very regular customers at tractor auction. Sometimes these farm tractor auctions are nearby and you can thus touch and inspect the second hand farm tractors for sale before you bid on them.
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.[1]

The Melroe brothers, of Melroe Manufacturing Company in Gwinner, North Dakota, purchased the rights to the Keller loader in 1958 and hired the Kellers to continue refining their invention. As a result of this partnership, the M-200 Melroe self-propelled loader was introduced at the end of 1958. It featured two independent front-drive wheels and a rear caster wheel, a 12.9 hp (9.6 kW) engine and a 750-pound (340 kg) lift capacity. Two years later they replaced the caster wheel with a rear axle and introduced the M-400, the first four-wheel, true skid-steer loader.[2] The M-440 was powered by a 15.5 hp (11.6 kW) engine and had an 1,100-pound (500 kg) rated operating capacity. Skid-steer development continued into the mid-1960s with the M600 loader.
The main benefit of electric mowers is monetary--eliminating gas and oil consumption and the changing of filters and spark plugs. Electric mowers are generally quieter than their combustion engine counterparts. Electric mowers leave no carbon footprint, making them more environmentally friendly. Electric mowers are usually lighter and easier to use than gasoline engine mowers.

Hydraulic excavator capabilities have expanded far beyond excavation tasks with buckets. With the advent of hydraulic-powered attachments such as a breaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation. Many excavators feature a quick coupler for simplified attachment mounting, increasing the machine's utilization on the jobsite. Excavators are usually employed together with loaders and bulldozers. Most wheeled, compact and some medium-sized (11 to 18-tonne) excavators have a backfill (or dozer) blade. This is a horizontal bulldozer-like blade attached to the undercarriage and is used for levelling and pushing removed material back into a hole.

A skid-steer loader can sometimes be used in place of a large excavator by digging a hole from the inside. The skid loader first digs a ramp leading to the edge of the desired excavation. It then uses the ramp to carry material out of the hole. The skid loader reshapes the ramp making it steeper and longer as the excavation deepens. This method is particularly useful for digging under a structure where overhead clearance does not allow for the boom of a large excavator, such as digging a basement under an existing house. Several companies make backhoe attachments for skid-steers. These are more effective for digging in a small area than the method above and can work in the same environments. Other applications may consist of transporting raw material around a job site, or assisting in the rough grading process.
I was happy with my $9,000 purchase price, if not a little stunned. Except for our house, which was only possible thanks to a big mortgage, this was the largest single purchase I’d ever made. More than my truck. More than my wife’s car. But auction houses charge additional fees that you need to be mindful of. At the auction I attended, the buyer’s fee was 10 percent for total sales under $1,000 and 1 percent for sales above $1,000. Credit card payments were an additional 2 percent, which I was OK with because I got the equivalent of 3 percent cash back in points and had the dinero to pay it right off – thanks to months of tight living.

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.
