A 2-pto motor brush hog. Rotor direct coupled to motors. Use Abe's new motors, 5 cu in. The cutter is a cross, 8" wide, with 8" of chain welded to tips. So each cutter has a 24" overall diameter. Thus we get 48" of cut from an implement that
A coumter-rotating time tiller driven by two high torque motors, same profile of motors as the 5 cu in. Motors ride on top, and are linked to the shafts via 100 chain here, since that is so expensive (including sprockets), please just use our existing 8 tooth sprocket and chain links without track pads as in our tracks. That will work well for high torque. A dust guard should be on top. Width of overall tiller should be 42", so hopefully 3' of tilling width. We can do 1/4" thickness for the chain link pieces.

Finished Bobcat quick attach mounting plate: File:Bobcat-QA-mounting-plate.FCStd
About 2hrs for QA plate
Uploaded files for standards of quick attach
Next thoughts: update in tractor model
I was pretty frustrated with the lack of construction geometry in FreeCAD. It's not even possible to create a construction plane, or to set an offset distance for a pad or pocket. This makes it SUPER difficult to get things done when you are used to SolidWorks or the like. Also, mapping a sketch to a sketch face, then mapping out the edges takes way too much time for my liking. Those would be fun things to improve upon...
