Abstract
Abstract Disclosed herein is a timber harvester in the form of a vehicle which comprises in unitary assembly, a main frame propelled by endless tracks, a forward boom which supports a timber felling chain saw, a log grapple, a delimber which includes a rotor with an axial throat for receiving felled timber, and four circumferentially arranged cutters that are movable at an acute angle relative to the threat to severe limbs from the felled timber, a food mechanism for drawing the timber through the delimber, a cut-off saw swingably mounted for movement transverse to the linear feed path to cut the timber into predetermined lengths and a log unloading assembly for palletizing or stacking the cut logs.

375 words
A timber harvester comprising in unitary assembly a main frame, a sub-frame pivotally mounted on said main frame for swinging movement about a vertical axis, a forward boom pivotally mounted on one of said main frame and sub-frame, a grapple assembly, means mounting said grapple assembly on said main boom, a saw carrier frame, means for mounting said carrier frame on said forward boom to afford vertical swinging movement of said carrier frame about a first horizontal axis, means for mounting said carrier frame to said forward boom for vertical swinging movement about a second horizontal axis, means for turning said carrier frame about a generally vertical axis, a saw bracket, a cutter bar mounted on said saw bracket, a cutter chain carried by said cutter bar, a motor mounted on said saw bracket, said motor having an output shaft in driving engagement with said saw chain, means for mounting said saw bracket on said carrier frame to afford movement of said cutter bar in a linear cutting path, a guide member resiliently and elastomerically mounted on and cantilevered from said carrier frame and extending from said carrier frame and a sleeve on said saw bracket reciprocable on said guide member to guide linear movement of said cutter bar, a spike bar mounted on said carrier frame adapted to engage a tree trunk, a delimber mounted on said sub-frame, feed means adapted to withdraw timber through said delimber, said feed means being located aft of said delimber, a log unloading assembly comprising a log receiving chamber located aft of said feed means to receive logs from said feed means, a cut-off saw located between said feed means and said log receiving chamber, means mounting said cut-off saw for movement of said saw into the feed path of logs to cut a log extending through said delimber and into said log receiving chamber, means at the rearward end of said log receiving chamber adapted to engage the butt end of a log moving through said single log receiving chamber and energize said cutoff saw, said log unloading assembly further including a log accumulator bucket, and means mounting said bucket on said subframe, said bucket being upwardly open to receive logs discharged from said log receiving chamber.
