An off-feed conveyor for use with a woodworking mill machine, for off conveying wood workpiece output from the mill machine safely away from the mill operator. The conveyor includes a generally horizontal frame, and a movable endless conveying belt mounted in the frame with its upwardly facing outward surface defining a flat conveying surface for receiving the workpiece output from the mill machine. An adjustable height support frame is secured beneath the horizontal frame and supports the latter at a height appropriate for the belt surface to receive the workpiece output. Movement facilitating means are secured to the bottom of the support frame to enable movement of the conveyor toward and away from the mill machine. Contact engagement means at the lateral side of the horizontal frame, releasably attach the conveyor to the mill machine upon positioning thereat; and drive means move the belt in a direction to enable the off conveying.
