There are about a dozen development pages pertaining to each of the projects for the lifetrac. Scroll down on LifeTrac 6 - Development / Infographic and you'll see them listed there
I think it means this: 1. The bobcat attachment is new and therefore you must redesign the loader arm attachment to use the bobcat one. 2. The power cube compartment is too big for the articulated steering(probably) so you have to make it smaller. 3. The curl cylinder isn't a curl cylinder. A curl cylinder is the derivative in 3 dimensions of a cylinder, hehe. They are talking about the hydraulic cylinder that articulates the front loader. 4. The hydraulic system runs on one powercube so if you'd like to run it on more, you need to add a manifold to connect more lines into one. I'm no expert on these things so take this with a grain of salt.
For $106 you can get a hydraulic pump that's the same as the one on the motor and use it as a PTO. Mount it to a 3 point hitch and then bolt it onto the tractor where the holes are already in the steel. Then run a hydraulic line to it and it should work.
