These 20U class machines have been in production for well over 35 years offering the versatility of medium speed straight stitching, zig-zag stitching, satin stitch embroidery and free-motion work.
The 20U class has also been designed for natural, synthetic fabrics and for light weight leather with perfect straight stitching with up to 12mm of zig-zag stitches.
The Knee lifter can be used to raise the foot or control zig-zag width. Buttonholes are produced by means of right, center, and left needle positions. The needle bar frame locking clamp is engaged by a quick 1/4 turn of a knob.
With a built in bobbin winder and a hook that automatically advances and retards timing (according to zig zag width) the 20U class also incorporates an adjustable forward and reverse stitch length mechanism.

Have had this model & brand machine for several years and am so happy with it. I purchased a servo motor, since I live in an apartment and didn't want to disturb anyone with the idling. Love sewing on this machine...it is so smooth and like being able to control the speed. With just the change of the feed dogs & throat plate, the machine can easily change to a zigzag with up to a 12MM witdth, which is terrific for sewing knits....
