Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a remote-controlled tree trimmer and, more particularly, to a remote-controlled tree trimmer which allows pruning a palm using a remote-control device.

2. Description of the Related Art

Several designs for trimmers have been designed in the past. None of them, however, include a remote control which is used to move the tree trimmer upwards and downwards on the trunk of a tree.

Applicant believes that a related reference corresponds to U.S. Pat. No. 5,322,102 issued for a pruning device having a helical cutting head. Applicant believes that another related reference corresponds to U.S. Pat. No. 7,422,041 issued for a tree trimming device that automatically climbs a tree or other vertical members and shears limbs or debris as it climbs. None of these references, however, teach of a tree trimming device comprising a climbing ring having an attachment clamp, multiple cutting elements, and a motor which enables the three trimmer to travel up and down a trunk while trimming the trunk of the tree.

Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
