Power Cube IV

The plans on the OSE website are for version 4, but it is under renovation. I just completed version 5 (just delivered to Marcin) and am about to begin on version 6.

Version 6 will include several updates:
 * 28 HP engine
 * Larger 7 gallon fuel tank
 * Symmetric fuel/hydraulic tanks
 * Simplified engine mounting and access to pump & coupling
 * Thermostatically controlled oil cooling fan
 * Rubber vibration mounts for engine
 * Commercial muffler
 * Control / hydraulic panel



Here are my best answers to your questions - using Power Cube 6:


 * Weight: Approx 150 lbs dry. Hydraulic oil and fuel can add up to 100 lbs (14 gallons @ 7.3 lbs/gallon).
 * Dimensions: 27" x 27" x 27" cube
 * CG: If you mean "Center of Gravity", no data on this yet, but it will vary with fluid distribution in the tanks
 * Duration: No data yet, as we are using a new engine. This also depends on power usage.
 * Fuel: 7 Gallons

Notes:
 * The power is delivered via hydraulic fluid power through the quick coupler connectors.
 * The Power cube attaches to the LifeTrac with the quick attach plates - which are at 45 degrees.
 * I would like to add remote controls to the Power Cube via electronic interface, but haven't started on this yet. This will be very important for remote throttle, start & stop.
 * I have discussed with Marcin the possibility of working on a "MicroTrac" walk-behind two wheel tractor that would be like a LARGE, powerful tiller. I envision it to employ the Power Cube for power.  It could be just a drive train from a car.
 * I have also discussed with Marcin the possibility of splitting the Power Cube into two the engine and drive components, where the engine could be detached from the hydraulic pump via a quick connect shaft coupling. The engine could then be connected to something else (like a car?) for direct drive power.  This one is still in the concept phase, but seems reasonable.  The key component would be the shaft coupling.  Its components would have to be re-arranged, as the engine component could not rely on the presence of the hydraulic tank for support.
