Wheel loaders are four-wheel-drive earthmoving machines used primarily to load loose materials with a front-mounted bucket. A lift-arm assembly raises and lowers the bucket. Most wheel loader manufacturers classify their product lineup into four categories with these approximate power and bucket-capacity specifications: compact (40-100 horsepower, 1.0-2.5 cubic yards); small (115-180 horsepower, 2.5-6.5 cubic yards); medium (230-400 horsepower, 3.75-15.0 cubic yards); and large (with horsepower ratings up to 1,800 or more and capacities in excess of 30 cubic yards).
A backhoe loader, also called a loader backhoe, digger in layman's terms, or colloquially shortened to backhoe within the industry, is a heavy equipment vehicle that consists of a tractor-like unit fitted with a loader-style shovel/bucket on the front and a backhoe on the back.
