ABSTRACT:
A friction reducing slip member for the shaker arms of a tree shaking harvester. The slip member in one form is a thin flexible panel structured for placement outward or over a main pad of the shaker head. The slip member includes a peripherally sealed interior chamber fully containing a friction reducing material such as grease, silicone lubricant, powdered or granular lubricants, or coatings having low coefficients of friction such as polytetrafluoroethylene. The lubricant allows the outer surface or side of the slip member to be positioned against a tree and to remain stationary during the tree shaking mode. The opposite interior side of the slip member is allowed to move with the shaker head as the shock waves are carried through the stationary surface of the slip member to the tree. The stationary side wall positioned against the tree protects the bark and cambium layer of the tree from damage. The fully contained lubricant helps allow the outer side wall of the slip member to remain stationary and also reduces friction and heat build-up to extend the life of the component parts of the shaker heads. The sealed compartment maintains the lubricant or lubricating agents free of wear and friction increasing debris falling from the tree or otherwise associated with the shaking of trees in an orchard.
