803 CADThumb for the 821, 831, 841, 808
Just like the thumb on your hand, the 803 CADThumb will allow you to use the CADDigger to pick up rocks and logs and other odd shaped items.
The hydraulic force of the bucket insures the Thumb has a sure grip!
These plans detail how to add the CADThumb to the standard boom extension,
this will not work with the 801 Boom Extension
(NOTE: I seldom use my 821 that the CADThumb is not used at least once, there is always rocks that need moved)
The CADThumb will be a major "back saver" when you need to move logs, etc,, and it is great when you want to hold firewood off the ground while you cut the wood to lengths.
