General Duty (GD)
GD buckets are for digging in low-impact, low-abrasion
material such as dirt, loam, and mixed compositions of dirt
and fi ne gravel.
Heavy Duty (HD)
The most popular bucket style, HD buckets are a good
starting point when digging conditions are not well known
like a wide range of impact and abrasion conditions
including mixed dirt, clay, and rock.
Severe Duty (SD)
SD buckets are for higher abrasion conditions such as
well shot granite and caliche. Red area on bucket image
illustrates additional protection against wear as compared
to a GD bucket.
Specialty Buckets
In addition to the standard four bucket categories, specialty
bucket styles are available for the 320E LRR, each with a
different purpose:
• Ditch Cleaning buckets for cleaning ditches, slope
grading, and other fi nish work.
• Center-Lock Pin Grabber Performance buckets for
maximum digging performance while keeping the
versatility and convenience of a coupler.
• Wide Tip buckets for low impact material where leaving
a smoother floor and minimal spillage are necessary.
