A trailer having a having a hydraulic boom having a rear end with a crane for holding trees and an attachment for connecting the trailer to a truck on the front end. The trailer also has, at the extendable end, hydraulicly controlled supports for leveling the trailer at the front end. A process for moving the trailer having a front and a rear and a center of gravity between the front and the rear includes (1) attaching the trailer front to the truck trailer mount; (2) moving the trailer into position with the truck; (3) activating a hydraulic power source independent of the trailer; (4) lifting the front of the trailer from the truck trailer mount using two balanced hydraulic pistons on either side of the trailer and forward of the center of gravity of the trailer powered by the hydraulic power source.

What is claimed is: 1. A trailer having a front end and a rear end supported on the ground by at least two wheels and attachable to a vehicle and a powered boom for moving or cutting trees comprising: (1) a bed having a front end and a rear end and a left side and a right side and wherein the front end comprises a first attachment means for attaching to the vehicle and wherein the rear end comprises a second attachment means for attaching the powered boom; (2) a power generator means for generating hydraulic power connected to the powered boom; and (3) a leveling means for mechanically leveling the bed comprised of (A) at least one first piston cylinder operationally attached to the power generator means; (B) a first piston arm having a low end and a high end, said high end movably extending from the at least one first piston cylinder in response to hydraulic power from the power generator means to lift the rear end relative to the front end; and wherein the at least one first piston cylinder is attached between the front end of the trailer and the rear end of the trailer. 2. The invention of claim 1 wherein (A) the at least one first piston cylinder is attached to the left side of the bed and wherein the leveling means further comprises; (D) at least one second piston cylinder operationally attached to the power generator means attached to the right side of the bed, (1) a second piston arm having a low end and a high end, said high end movably extending from the at least one second piston cylinder. 3. The invention of claim 1 wherein the power generator means comprises a motor, a hydraulic pump connected to the motor, a reservoir connected to the pump and hydraulic fluid in the reservoir mounted on the powered boom and wherein the second attachment means further comprises a hydraulic swivel means for rotationally holding the power generator means and for carrying hydraulic fluid from the hydraulic pump to the at least one hydraulic cylinder. 4. The invention of claim 3 wherein the power generator means further comprises a valve means for selectively supplying hydraulic fluid to the boom means or the at least one first piston cylinder. 5. The invention of claim 4 further comprising a sensing means for sensing the level of the trailer and supplying hydraulic fluid to the at least one first hydraulic cylinder for automatically leveling the trailer. 6. The invention of claim 1 wherein the trailer bed further comprises (1) a low arm having a front end and a rear end and a left side and a right side; (2) a rising brace having a high end and a low end and wherein the rising brace low end is attached to the low arm rear end; (3) a high arm having a having a left side, a right side, said high arm also having a front end and a rear end and wherein the high arm front end is attached to the rising brace high end; (4) a high arm extension means for extending the length of the high arm from the brace outward. 7. The trailer of claim 6 wherein the extension means further comprises at least one extension brace having a front and a rear and a middle, said extension brace being slidably in contact to the high arm rear end. 8. The trailer of claim 7 wherein the extension means further comprises at least one power means for moving the at least one extension brace rear away from the high arm rear end. 9. The trailer of claim 8 wherein the power means further comprises a hydraulic cylinder and piston having a first end operationally movable away by action of the cylinder from the second end, said first end being mounted onto high arm and said second end being attached to the at least one extension brace. 10. The trailer of claim 9 wherein the high arm defines a tubular opening and wherein the at least one extension brace fits within the tubular opening. 11. The trailer of claim 10 wherein the tubular opening is defined outside of the high arm. 12. The trailer of claim 8 wherein the at least one extension brace is on the high arm left side and further comprising at least one second extension brace connected in the same fashion to the high arm right side. 13. The invention of claim 5 wherein the first piston arm low end further comprises a log gripping means for holding the first piston arm low to a log. 14. The invention of claim 1 further comprising at least one second lifting means for lifting the trailer and the leveling means.
