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.
A zero-turn lawn mower is a riding mower that has a zero-turn radius--meaning it spins as opposed to turning like a standard vehicle with front-wheel turning. Basically, these things can turn on a dime. Instead of a steering wheel, most models have levers to control speed to each drive wheel, using a hydraulic-based system. They are considered faster and more efficient than standard riding lawn mowers. Because of this unique feature, they can be more expensive.
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]

Hydraulic excavators usually couple engine power to (commonly) three hydraulic pumps rather than to mechanical drivetrains. The two main pumps supply oil at high pressure (up to 5000 psi) for the arms, swing motor, track motors and accessories while the third is a lower pressure (~700 psi) pump for pilot control of the spool valves; this third circuit allows for reduced physical effort when operating the controls. Generally, the 3 pumps used in excavators consist of 2 variable displacement piston pumps and a gear pump. The arrangement of the pumps in the excavator unit changes with different manufacturers using different formats.
The {Caterpillar (CAT) 320DL} is a massive excavator that is designed for medium to large jobs. This is not the unit that you'll see digging out a swimming pool in a residential area. Rather, these units traditionally see use in the energy or natural resource extraction market, or in larger-scale commercial operations. Boasting a 389 cubic inch CAT diesel motor, this 50,000 pound unit is powerful and capable, yet still transportable on a flatbed trailer behind a tractor trailer.
An excavator is designed to do one thing well - to dig out trenches, footings, and foundations with ease. Excavators are available in a variety of sizes, from the micro-excavator units that are adept at navigating tight urban or residential areas, to the massive earth-moving units that can scoop thousands of pounds of material in one pass. With the popularity of excavators at an all time high, it pays to understand the differences between competing models. Then, you can make an educated choice on a model that will serve your crew the best.

With my ideal tractor in mind, I was able to cut the list of 60 or 70 tractors for sale down to 20 or so. Before I got into seeing what those 20 fetched online, I dug into tractor forums looking for hands-on reviews. The New Hollands in the size class I was after, I found, were actually rebranded LS tractors, made in South Korea. A neighbor loaned me an LS awhile back and I wasn’t in love with it. The old Allis-Chalmers was a great machine, but parts were hard to find. A couple of the John Deeres had really positive chatter, as did the L3750, which a couple of guys on the Kubota forum said might be the best tractor Big Orange ever made. Before I started pricing the tractors out, that list of 20 or so was cut in half.

I called my pal, Kyle, who runs Van Galder Family Farms in Alpine, New York, and my friend and mechanic Bill Phelps, of Phelps Auto in Lansing, New York. I told them what I was up to and they gave me a punch list of things to look at. Kyle, I found out, would be at the auction and could kick tires with me. That night before the auction, I typed out the accompanying checklist of things to look at before the bidding started.
