A system for and method of evaluating a log. The system includes an analysis module having at least one input terminal connectable to the at least one input device. The at least one input terminal is operable to receive at least one signal representing at least one measured property of the log and at least one determined parameter of the log determined in response to an energy being applied to the log. The analysis module further includes a processor coupled to the at least one input terminal. The processor determines a predictive modulus of elasticity (MOE) of the log based at least in part on the at least one measured property and the at least one sensed parameter. The analysis module also includes an output terminal coupled to the processor and connectable to an output device. The output terminal transmits a third signal representing the predictive MOE.

A tree harvesting device which continuously severs and collects trees in a motion which is not governed by the motion of the carrier vehicle is described. The carrier vehicle moves from tree to tree in a continuous motion while the severing mechanism severs each tree in turn and then loads the cut trees into containment means within the harvester. Once the harvester is fully loaded, the containment mechanism releases and the harvester deposits the load in a bunched pile ready for subsequent handling and processing.
