That 16,000 pound planer has a 25 HP 660 V 3 Phase motor to drive the hydraulic motor, which as I recall has a 50 gallon reservoir. The thing is huge, but years ago when i first met him, he had, in his 20,000 square foot barn/shop a larger one, bed was 8 feet by 16 feet, twice the size of the current one. He donated that one to a museum somewhere, they sent a rigger and semi to transport it. It had a huge diesel engine to power the hydraulic motors on it. I only saw it running once, it would take tool bits in the planer head up to 6 inches wide in groups, or one single bit in the center that was 12 inches wide.
Don't remember the manufacture brand, but it was painted a sea foam green color, and he said that was the original factory paint job.
