Backhoe loader

The backhoe loader is one of the most common pieces of heavy equipment on any size job site. The fact that it features two useful tools in one machine makes the backhoe loader a must-have for all kinds of construction and repair projects.

The standard backhoe consists of a diesel-powered, four-wheeled vehicle with the operator’s cab in the middle and a tool on each end. On the front, it has a loader: a wide bucket on dual arms that is used to either pick up loose piles of material or to push dirt back into a hole when a job is finished. The rear end has a backhoe — a hydraulic-powered digging scoop on a three-jointed arm, designed to dig through hard earth. The operator needs only to turn around in his seat to switch from digging a hole to filling it back up.

Digging and refilling holes and trenches is commonly required for all kinds of construction, utility work, and landscaping. The ability to exchange the backhoe or loader bucket for a different attachment gives you even more flexibility: crushers, retractable-bottom buckets, grinders, and other tools can handle a variety of other tasks. The combination of power, relatively small size, two common tools, and flexibility makes backhoe loaders extremely useful for contractors and construction firms of many types.

Considerations to Sale of Backhoe Loader

Part of backhoe loaders’ popularity is based on the fact that they fall in the middle of a range of digging and loading equipment, bringing more power than compact machines without the expense of full-sized excavators. You should consider whether a backhoe loader is the right choice for the bulk of your digging and earthmoving needs.

For smaller jobs and increased flexibility, the combination of a skid steer loader with a standard bucket and a mini excavator can sometimes work faster than a backhoe loader. It can be cheaper to buy the two smaller machines than one backhoe loader, but you’ll need an operator for each one and you’ll have more transportation and maintenance hassles. These mini machines are most valuable in very crowded conditions, and recent trends have many contractors replacing at least one backhoe with a mini excavator.

For high-end digging power, full sized excavators are the best choice. These massive tracked machines are only worthwhile if your application calls for ongoing digging: building foundations, for example. However, their size makes them less useful on cramped construction sites.

Backhoe loaders fill a very important middle ground, where having an excavator and loading bucket on one relatively compact machine is essential. They’re also much better at moving around large job sites or between sites — you can drive a backhoe on the road if need be, while excavators and skid steers have to be moved on trailers.

Choosing a backhoe loader

The first consideration when choosing a backhoe loader is how deep you’ll need it to dig. Full-sized backhoes can usually reach down 14 to 16 feet; compact backhoes can typically dig around eight to 10 feet deep. For full size machines, 14′ depths are by far the most common. Compact backhoe loaders are great if most of your work is less than 10′ deep — they’re less expensive, easier to maneuver, and easier to transport than full-sized backhoes.

On the other end, reach can be important: if you need to load dump trucks of a certain size, make sure the loader has an appropriate lift height to do the job. Lift capacity is similarly important: you’ll need to know how much weight your machine can handle. Keep in mind that capacity varies for the two tools — loaders typically have much greater capacities than backhoes.

One spec that you shouldn’t put too much emphasis on is horsepower. Engine horsepower doesn’t directly impact the capabilities of the attachments: digging and lifting are powered by the backhoe’s hydraulic systems, not the engine. You should be aware of horsepower ratings when comparing different models, but don’t let them drive your decision.
