For a standard household lawn mower under normal conditions, it is recommended to sharpen the blades twice a mowing season. It’s important to keep the blades sharp as they cut grass faster and cleaner, and this cleaner cut promotes faster lawn regrowth. If you notice decreased performance, uneven cutting patterns, or it is taking longer to mow your lawn, it might be time to check the blade. Take the mower to a certified blade sharpener.
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.

Excavators typically feature a boom and arm, equipped with a bucket attachment that is used for digging. Unlike its cousin, the Mini Excavator, these units typically feature an enclosed cab for the operator; and have the ability to dig at greater depths and distances from the machine. While these units are typically tracked, IronPlanet sells Wheel Excavators as well. Browse popular models from top manufacturers including Cat Excavators, Hitachi Excavators, John Deere Excavators, Komatsu Excavators, Volvo Excavators and others. Be sure to check out our Excavator Attachments for your chance at a new bucket or thumb.
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.
