Hydraulics

• September 13: The hydraulics diagram is good except it shows the motors wired in series. They should be wired in parallel. The series configuration shown will give us 1000 lb of pushing force, and the parallel configuration will give us 4000 lb of pushing force from our 30" diameter wheels.

• September 14 response: This makes sense. Are you asking for a new diagram showing all of this? No problem, but remember Rob's Fast, Good, Cheap Tiangle: You can only choose two.
  • It sounds like a good set-up, but then there will be no hoses running between the joysticks.

Power Cube

• September 13: Note that the design is for one power cube only. If we use 2 power cubes - so we can run the pulverizer - then we need to connect one power cube to each valve, with the two valves being independent systems. This could by done if we route the Pulverizer and Loader Lift/Curl through the 3 spool joystick valve (first power cube), and the wheel drive/turning through the other valve (and second power cube).
  • This means that each valve must have quick couplers, so we can rewire the system for the 2 power cube case.
  • The bottom line is: fluid can't mix between the two power cubes, or it will begin to spill. Each power cube must have its own closed circuit, with no fluid mixing between the cubes.
