A sewing machine includes a feed mechanism which feeds a workpiece by a feed dog partially protruding out upward from an upper surface of a throat plate and moving along a predetermined feeding direction; a presser foot which presses the workpiece on the upper surface of the throat plate from above; a feed guide which has an abutting surface along the feeding direction and guides feeding of the workpiece; and a control device. The feed mechanism includes a lateral feed mechanism which adds a moving component in a direction along the upper surface of the throat plate and orthogonal to the predetermined feeding direction, to the feed dog. The control device controls the feed mechanism to feed the workpiece by adding a moving component to a side of the abutting surface of the feed guide by the lateral feed mechanism, in addition to the feeding along the regulated feeding direction.

A sewing machine includes a feed dog partially protruding out up and down from a throat plate to feed a workpiece, a sewing needle configured to perform stitch points on the workpiece by moving up and down, and a shuttle configured to capture an upper thread passed through the sewing needle below the throat plate to be entwined with a lower thread. The feed dog includes a top plate having teeth formed on an upper surface thereof, and a support portion to which a feed operation relative to the top plate is input. The top plate includes an insertion hole that the sewing needle penetrates up and down, and a pair of wall portions extending in an up-and-down direction respectively on one side and another side in a feed direction of the workpiece relative to the insertion hole on a lower surface side of the top plate.

A kit for adding or replacing an automated upper walking foot stepping height adjustment to a sewing machine, the kit includes a mounting assembly including an actuator bracket, an actuator coupled to the actuator bracket, a drive assembly, and a needle drive assembly. The actuator includes an actuator shaft that extends and retracts. The drive assembly includes a drive shaft, a drive arm coupled to the drive shaft and the actuator shaft, and a guide coupled to the drive shaft. The needle drive assembly includes a variable drive crank coupled to the guide and configured to couple to a needle drive shaft of a sewing machine. Selectively extending and retracting the actuator shaft selectively adjusts a stepping height of an upper walking foot.
