A feeding apparatus includes opposing arms pivoted to a frame, two opposing feed rollers installed in the arms as the only feed rollers for feeding a tree through the throat, hydraulic motors driving the feed rollers and at least two pressure-medium lines operating the hydraulic motors.

Described are systems and methods for treating and/or helping prevent microbial infections on plants and trees by applying a treatment solution to cut areas of the plants or trees that have been exposed during a hedging or topping operation, or the like. The method can include providing a liquid application system including treatment liquid, wherein the liquid application system is integrated with at least one of a motorized hedging and/or topping vehicle, wherein the liquid application dispenses the treatment liquid at a controlled rate of flow from the one or more nozzles and the treatment liquid is applied directly and uniformly from the one or more nozzles on the second boom to the one or more cut areas at the controlled rate of flow.

The invention relates to the mounting of knife inserts in apparatuses which require occasional or frequent replacement of the knife insert due to wear or damage of the knife, as is the case in delimbing machinery used in the forestry industry. The invention also relates to a knife carrier, a tree processing head, and to a method of installing a knife insert to a knife carrier. A knife insert for use with a knife carrier includes a blade portion, a retention portion configured to interface with a corresponding receiving portion of the knife carrier, and a force transmission means configured to introduce a preload from the knife carrier to the knife insert, wherein the preload is configured to force the retention portion against the receiving portion along a length of the blade portion and thereby removably hold the knife insert in place in the knife carrier.

The climbing palm tree trimmer may ascend and descend a tree trunk of a palm tree in order to trim the top of the palm tree. A cutting ring may rotate within a housing ring so that a plurality of blades projecting upwards from the cutting ring may cut trimmings from the palm tree. The cutting ring may separate such that the cutting ring may be placed around the tree trunk and reassembled. The housing ring may likewise separate such that the housing ring may be placed around the tree trunk and reassembled. A plurality of drive units may move the climbing palm tree trimmer up or down the tree trunk. Up and down movements and activation of the cutting ring may be controlled from the ground using the trimmer control box.

A timber working device, comprising a frame, having a feed axis, a drive system, configured to feed at least one stem along the feed axis, at least a pair of upper knives or lower knives movably attached to the frame, wherein the knives are configured to be controllable each by an actuator to open and close around a stem, a tilt mechanism comprising a controllable tilt bracket pivotably attached to the frame, to control a tilt position of the frame in relation to the tilt bracket.
