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,[9] 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.

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.

Thanks to a simple selector-switch, Mecalac patent, the driver can turn his compact excavator into a compact loader and then back again, using the same commands. Loading efficiency is maximized, it is made by the skid bucket supported on the blade which increases the machine’s efficiency thanks to the force of the thrust transmitted directly from the chassis to the bucket. The operation is performed more accurately using the control lever. The patented Mecalac cylinder coupling function, allows to synchronize the boom cylinders for perfect movement coordination and precision. It makes driving and handling easy, regardless of whether the operator is a novice or more experienced. And, whether engaged or otherwise, they’re yet another powerful feature along for the ride.
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.
Excavators (hydraulic) are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house".[1] The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.[2] Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements.[3]

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.
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.
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.
The Kubota was definitely not pretty. It had clearly spent its life sleeping outside. I tried to start it and nothing happened. But when Kyle brought over a jump pack it started right up. Right away it would need a battery. We started to make a list: battery, leaky swing arm on the backhoe, the filters were all old – one of them dated 2010 – two hydraulic hoses needed replacement … I Googled parts and prices on my cell phone before the bidding started. Those replacements, plus all new fluids I figured would take another $1,000 ballpark to get the machine back to level.
Tractor paid for, and loaded on to Kyle’s trailer, I called my wife. After a brief “conversation” about the home renovations all that cash could cover, the tractor was dropped off at Phelps’ garage. Rather than me figuring the machine out, I had Bill give it a once over, replace all the fluids, the few bad hoses, straighten the bent loader bucket, and re-pack that leaky swing arm cylinder. There was a new battery, too, and a few other things, which rung up to $1,500 or $500 more than I had anticipated before I started bidding.
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.
