  • Patent number: 6640855
    Abstract: A log processing machine and associate method employs one or more log guides to make joinery cuts in a processed log which has at opposed edges of the processed log the raw log's natural external contour. In a preferred embodiment of the invention, each log guide includes a straight edge and is attached to the processed log to create an artificial straight edge for guiding the processed log through the joinery machine. Prior to attachment, centerlines are marked on the log guide and the processed log, and the centerlines are aligned when the log guide is attached to the processed log. The processed log, with the log guide attached, is then moved through the machine with the aid of computer control while the straight edge of the log guide follows a fence. In this manner, the position of the processed log and its centerline are always known so that the computer can make the programmed joinery cuts with high precision.

  • Patent number: 6640851
    Abstract: A stump grinding apparatus of the type adapted to be mounted in a frame on the end of a boom is described. The apparatus comprises a grinding wheel mounted between hubs keyed to a shaft that is connected though belts and gears to a source of motive power, such as a diesel engine. A pair of non-adjustable roller bearings are used to provide relative movement of the shaft and grinding wheel in the frame. The apparatus includes means for providing lubrication between relatively moving parts so that the life of the bearings and other component parts can exceed 5000 hours of use without failure. The shaft assembly includes dimensional tolerances that protect the moving parts from the ingress of dirt and other debris. The materials of construction are selected to also enhance trouble-free operation.

  • Patent number: 6637482
    Abstract: The innovation concerns a wood harvesting method and a harvester head. The method is used to harvest all sizes of trees without to take the harvester to the site more than once. The method consists of placing the harvester head against the first tree, closing all grapples around the tree, cutting the tree with the cutting device, lifting the cut tree a little by holding it with the grapples fastened to the telescopic boom and using the stroke cylinder to move the telescopic boom in relation to the main body, moving to the next tree, opening the rigid grapples and holding the first tree in an upright position with the articulated grapples, closing the rigid grapples around the tree, opening the articulated grapples, so that their turning tips slide away from between the trees, closing the articulated grapples around all the trees, cutting the tree with the cutting device, and continuing the work in the above described order by collecting more trees and cutting them, until the grapples are full.

  • Patent number: 6634284
    Abstract: A round bale baling apparatus includes an accumulator for rolling crop material into a round bale, a twine dispenser adapted to hold and dispense twine, and a twine tensioner. The twine tensioner is adjustable and includes an energizable actuator and switch for operating the actuator to adjust the twine tension. Specifically, the switch can be manipulated to selectively decrease tension on the twine during initial gripping of the free end of the twine by a rolling loose bale, and to selectively increase tension on the twine once the twine is sufficiently wrapped onto the bale to provide a secure pulling force. The actuator can be electric, such as a reversible DC motor or solenoid, or can be another energizable device actuable from a remote position. Methods related to the above are also defined.
