A self-propelled palm tree trimming and trunk skinning apparatus is disclosed which includes first and second curved arms pivotally affixed, at their respective first ends, to a coupling member. At the opposite ends of the curved arms, a tension spring is provided to pull the two arms toward one another. A cutting blade is carried by one of the curved arms, and the blade edge is oriented at an angle from the horizontal when the apparatus is operatively engaged with a palm tree trunk. A d-c motor/speed reduction unit/cog wheel system is provided for circumferentially driving the apparatus such that the cutting blade, as a result of its skewed orientation, causes the apparatus to follow a spiral path upwardly, the cutting edge of the blade skinning and trimming the trunk of the tree as it ascends. Upon completion of the operation, the direction of the motor is reversed permitting the apparatus to spiral downwardly. The reversible motor is preferably energized from an integral rechargeable power pack and is manipulated from a control box connected by a cable to the apparatus and suspended for access by an operator standing at ground level.
