The backhoe is a simple hydraulic arm and bucket which attaches to the front of the [[LifeTrac]] and is used for digging holes and trenches.  The backhoe is one of the most basic dirt working tools and is a common attachment to many small tractor and skid-steer vehicles.  It can be used for digging trenches for foundations, digging up material to make compressed earth blocks, digging waste pits, and many other common building/farming tasks.  Furthermore, by attaching a chain to the bucket, the backhoe can be used to lift and transport heavy loads such as engine blocks, battery packs, long pieces of pipe, etc.
 
Commercially manufactured backhoes vary greatly in their size and capabilities and therefore vary significantly in price.  A quick google search seems to indicate that relatively small, simple devices like the one we are considering range from 2 to 4 thousand dollars with more sophisticated attachments approaching 10 thousand dollars.

There seems to have been a simple first attempt at the design made about the time the LifeTrac I prototype was in early operation.  This design can be seen in the photo at the right.

A prototype backhoe attachment has been built and used at [[Factor e Farm|the farm]].  There is a short clip of the backhoe laying on the ground in this clip from 0:28 to 0:30:

Here is a preliminary CAD design based on the footage from the above video.  After a few days when people have had a chance to comment on this design and after I have added any finishing touches to it I will post the actual BRL-CAD .g file this image is rendered from and/or a 2d sketch for people to add dimensions to so the exact dimensions can be worked out.
