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 original skid-steer loader arms were designed using a hinge at the rear of the machine to pivot the loader arm up into the air in an arc that swings up over the top of the operator. This design tends to limit the usable height to how long the loader arm is and the height of that pivot point. In the raised position the front of the loader arm moves towards the rear of the machine, requiring the operator to move extremely close to or press up against the side of a tall container or other transport vehicle to get the bucket close enough to dump accurately. At the highest arm positions the bucket may overflow the rear of the bucket and spill directly onto the top of the machine's cab.
There’s also a cost in getting a tractor home. If you own a big trailer, this isn’t a concern, but if you don’t – and live far away from the auction yard – that bill can run a few hundred dollars. Kyle volunteered to haul whatever I bought the hour south to my place. So, with the repairs plus transport, I wagered the Kubota would cost $1,000 above what I bought it for. My new high price was $10,000 and, frankly, I thought it would go for a lot more than that.

Knowing how much tractor you need is a separate problem all together. The answer depends on the work you intend to do. What implements will it pull? Is the main job brush hogging an established pasture or finish-cutting a lawn? Do you need tires that won’t trash the yard or more aggressive treads and 4-wheel drive so it won’t get bogged down in the woods? I was after a 30-to 50-horse machine with 4-wheel drive, and a frontend loader. Because much of my land is forest that I’m clearing for food plots and pasture, I wanted something heavy enough to take a beating and pull an 8-foot tiller or brush hog.

There are two main types of "Control" configuration generally use in excavators to control the boom and bucket, both of which spread the four main digging controls between two x-y joysticks. This allows a skilled operator to control all four functions simultaneously. The most popular configuration in the US is the SAE controls configuration while in other parts of the world, the ISO control configuration is more common. Some manufacturers such as Takeuchi have switches that allow the operator to select which control configuration to use.
