	* Figure out the problem with mounting the fingers to the tractor at a width that meets the standard. The closest we can get on our 4" grid is 8 holes apart (32" between middles of fingers) but this doesn't quite meet the standard so not all outside equipment will fit on this. This problem may already have been discussed and figured out so look through the work logs first. If there's no great solution there, we probably need a custom mount which holds the fingers the right distance apart and can itself be mounted to the grid. As of Oct 2013, the fingers are mounted 9 holes apart on the [[LifeTrac 6]] and the big bucket and backhoe should work with that.		* Figure out the problem with mounting the fingers to the tractor at a width that meets the standard.
