A sawmill assembly includes a bed and a carriage. The bed has a pair of substantially parallel rails, and the carriage is movably supported along the rails. The bed includes an extension bed member pivotably attached to a main bed member with a combination bunk/hinge to allow an operator to fold the bed between an extended in use position and a stowed position for transporting the sawmill assembly to or from a work site with a tow vehicle.

A pruning machine (12) for pruning vegetation growing on generally horizontal support wires. The pruning machine (12) includes a vertical shaft (22) mounted for rotation and at least one blade assembly (26) mounted on the shaft (22). The blade assembly (26) includes a plurality of blades (30) mounted to rotate with the shaft (22). The shaft (22) is threaded at least in the region where the blade assembly (26) is mounted. The vertical position of the blade assembly (26) on the shaft (22) is adjustable by an adjustment nut (56) which threadably engages the shaft (22) below the blade assembly (26) and which during adjustment, bears against the underneath of the blade assembly (26) so that rotation of the nut (56) upwardly of the shaft (22) raises the blade assembly (26) and rotation of the nut (56) downwardly allows the blade assembly to lower.
