Quick-disconnect hydraulic hose fittings and
hydraulic controlled locking pins permit these

Two types of front-end loader buckets are
commonly used: a general-purpose bucket (fig. 9-6) and
a multi-segment (4-in-1) bucket, also known as a
multipurpose (4-in-1) bucket (fig. 9-7). Both types may
be equipped on crawler or rubber-tired wheeled loaders.
The general-purpose bucket is a single-piece
bucket constructed of heavy-duty, all-welded steel with
bolted or welded replaceable cutting edges. Also
attached are bolt-on replaceable teeth (fig. 9-8) that
allows the bucket to be used for excavation of
The multipurpose (4-in-1) bucket is also
constructed of heavy-duty, all-welded steel with bolted
or welded replaceable cutting edges. This bucket
also has bolt-on replaceable teeth attached that
provide for excavation of medium-to-hard materials.
However, the multipurpose (4-in-1) bucket has a two-
piece construction that makes it more versatile than the
