In 2012, OSE started the Backhoe 2 (Deep Dig) redesign. The goals of the new backhoe are:

For Oct 2013 work:
As of Oct 12, 2013 we're not exactly following the [[Bobcat Standard Quick Attach]] because it doesn't line up with our grid and we didn't want to diverge from the backhoe design right now to make a custom mount. The mounts are a little narrower than the standard. We can improve this later.

* The main open issue is redesigning the main pivot so that we have somewhere to mount the hydraulics to get as close to 180 degrees of side to side movement.

Design Boards

The design boards are the main dashboards for tracking all development including documentation and all other tasks related to creating a new machine.

Requirements

As of Oct 12, 2013 we're not exactly following the Bobcat Standard Quick Attach because it doesn't line up with our grid and we didn't want to diverge from the backhoe design right now to make a custom mount. The mounts are a little narrower than the standard. We can improve this later.

Designs

The main model for the backhoe 2 is File:Backhoe deep dig.skp.

Here are some other designs for inspiration or experimenting:
