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". 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. 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.
Excavators are versatile and efficient. For those seeking a new or used machine for rent or purchase, Rock & Dirt is the place to search.

Our sellers and advertisers have decades of experience and can connect you to the machine that your fleet needs.
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.
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.
