Juki DDL-8700 review

Juki DDL-8700 is a mechanical sewing machine in the $500 to $1,000 price band, scored 8.4 out of 10 for heavy-duty sewing. Juki publishes a top speed of 5,500 spm and 1 built-in stitch.
Owners of the Juki DDL-8700 split on how much it will take. Several praise the build and the smooth, quiet running, but the heavy end is contested: one owner has run 15 oz denim and would not do so repeatedly, and another could not sew split or deer leather. Thread is the recurring headache, with owners reporting top-thread knots left on the underside and top thread showing underneath on heavy bonded nylon even with the tension nearly fully tightened. Reported faults include a motor that turned backward at first, a needle that did not stop in the up position, and a hook assembly with slight play. This read covers 60 Reddit threads and 2 retailer pages from 2010 to 2026. Reddit threads about this machine are mostly people asking for help, so problems are over-represented here.

A real factory lockstitch for a home workshop, if you have a table, a motor and the floor space; Juki classes the base model as medium-weight.
Specs
Checked against Juki 2026-10-01Juki's documents vs dealers
3 checks- Speed: Juki's page gives 5,500 stitches per minute for the base DDL-8700 and 4,000 for the DDL-8700A and DDL-8700H; marketplace listings pool the variants under similar titles, so a quoted speed may belong to a different variant.
- Arm space: a review site states about 11 in from needle to arm; not found on juki.com in accessible snippets. Left null pending a Juki PDF check.
- Price: $999 (Walmart, servo and table, DIY assembly) vs $899.99 (second Walmart listing) vs $1,004.40 (DDL-8700-H variant). The Sewing Machines Plus listing has an assembled table but no price in the snippet.
- Thread trimmer: Juki's page names none on the base DDL-8700; dealer and owner sources name the DDL-8700-7 as the trimmer variant, and listings often mix the two.
- Weight: Juki's product page and manual do not publish a weight, so it shows as [verify]. A 61.7 lb figure circulates in non-maker sources and is not used.
