Abstract: A swivel connector includes: an inner body having a first end and a second end opposite to the first end, the inner body defining an inner port at the second end for receiving a first fluid connection; and an outer body captively rotatable about the inner body, the outer body defining an outer port for receiving a second fluid connection, the inner body and the outer body cooperatively defining an annular passage therebetween, and the inner port extending within the inner body to the annular passage and the outer port extending within the outer body to the annular passage so as to form a passageway operable to permit a flow of fluid between the inner port and the outer port. The swivel connector of the present invention permits a first connected hose to swivel about a first axis that is perpendicular to a second axis with a second connected hose.

Abstract: A saw bar clamping mechanism, length measuring mechanism, system for measuring the length of a tree stem, feed roller mechanism, pin retention mechanism, and a tree processor attachment comprising at least one of the mechanisms and/or system is provided. The saw bar mechanism simultaneously unclamps a saw bar and releases a saw chain for convenient removal. The length measuring mechanism comprises a measuring wheel operable to extend and retract perpendicularly to a tree stem. The feed roller mechanism includes first-side and second-side rollers, and a bearing having outer and inner sides, the bearing being rotatably coupled at its outer side to the first-side roller and rotatably coupled at its inner side to the second-side roller, the bearing making angular contact. The pin retention mechanism includes a two-part collar fitting into a groove with interference for locking a nut received by the collar.
