Frequently asked
Does it arrive assembled?
Yes — we assemble, calibrate and test-stitch it in Miami before shipping. To protect the machine during freight, the head ships detached from the table; remounting takes minutes and we can walk you through it by phone.
Can I finance it?
Yes. You can split your purchase into monthly payments with Affirm (checking your rate takes seconds and won't affect your credit score), and Synchrony offers special financing on qualifying purchases (subject to credit approval). See your options on the financing page.
Warranty & support?
Yes — on top of the manufacturer's warranty, Supra Sewing backs your machine with our own coverage: 90 days on mechanical defects and 12 months on electrical & electronic parts — and since this is a Speedway, your electrical & electronic parts are covered for 18 months, serviced by our in-house techs in Miami, FL. Support in English & Spanish: +1 (954) 681-3894 or WhatsApp.

Description
Description
The SPEEDWAY® SW-4420N is a double-needle flatbed unison feed (Triple Feed) walking foot lockstitch machine for sale, complete with table and stand. Engineered for consistent parallel stitch lines on leather, upholstery, canvas, and heavy layered fabrics, it combines a triple-feed system — walking foot, needle feed, and bottom feed — with a direct drive servo motor and automatic lubrication for reliable production-level performance. Available in Four needle gauges: 1/4" (6.4 mm), 5/16" (8 mm), 3/8" (10 mm) and 1/2" (12mm)
What's Included
- SPEEDWAY® SW-4420N double-needle walking foot machine head (ships assembled)
- Servo motor, mounted and wired
- Industrial table and stand, fully assembled
- Built-in bobbin winder and thread stand
- Standard needle gauge set, needles, and basic accessory kit
Key Features
- Triple-feed (unison feed) system — walking foot, needle feed, and bottom feed all move together — prevents material slipping and puckering on leather, foam-backed upholstery, and multi-layer canvas
- Four needle gauge options (1/4", 5/16", 3/8", 1/2") let you match the machine to your application — tighter for bags and garments, wider for upholstery and automotive seams
- 750W Servo motor delivers quiet, energy-efficient operation with precise speed control from slow crawl to full production pace
- Automatic lubrication system reduces maintenance intervals and protects the machine during long production runs
- Flatbed construction provides a full, flat sewing surface — ideal for large panels, upholstery cushions, bag bodies, and canvas work
- Lockstitch formation produces strong, secure seams that resist unraveling — suitable for structural and decorative applications alike
Ideal For
- Leather goods and handbags — parallel topstitching with consistent gauge across the full panel
- Upholstery and automotive interiors — double-needle seaming on vinyl, leather, and foam-backed materials
- Canvas, webbing, and heavy textile work — heavy-thread parallel stitching on belts, straps, and covers
- Any production application where consistent twin-needle spacing and reliable material feed are required
