Sergers are powerful sewing machines that can help you save a lot of time and troubles. With a decent serger, you can easily and quickly complete hems on a clothing piece. Tasks that normally take four or five steps to be done can be accomplished in just two simple steps with a serger. Two popular sergers from Juki are Juki MO644D and Juki MO654DE. These two models may look quite similar at first, but there are some differences between Juki MO644D vs MO654DE that you should consider before choosing your serger.
Design and Dimensions
In general, these two models are indeed very similar to each other, but there are some notable differences in their designs. Juki MO644D has a somewhat unconventional design. Usually, the stitch length and differential feed controls are placed on the right-hand side so that these controls can be easily reached by the common dominant hand. However, Juki MO644D’s stitch length and differential feed controls are on the left-hand side, and actually the stitch length adjustment is placed inside the looper door. This is not a big deal; you just need to get used with it. (See also : Juki MO644D vs. Brother 1034D)
On the other hand, Juki MO654DE is relatively easier to set up. You can do flip and roll hems easily with this model. In addition, regarding the dimensions, Juki MO654DE is slightly bigger and heavier. The increased dimensions and body weight are due to a few additional parts that we will discuss in the next section.
The features of Juki MO644D vs MO654DE are largely similar. They come with similar stitches, which include the 4-thread overlock, 3-thread flatlock, 3-thread overlock, 3-thread narrow overlock, 3-thread rolled hem, 2-thread overcast, and 2-thread rolled hem. They both also have snap-on presser feet, industrial tension and cutting systems, and color-coded thread paths. Most of the included accessories are also similar.
However, there are some features that are only available on Juki MO654DE and not available on Juki MO644D. These features include the fast two-thread conversion and micro safety switch. The two-thread conversion is very useful when you to quickly swap between the three-thread and two-thread stitches. In addition, Juki MO654DE also comes with the ability to disengage the loopers for fast and easy threading.
The question is, do you really need these additional features? As a matter of fact, the additional features are mainly useful for people who need to handle lots of clothing pieces regularly. The two-thread conversion and the ability to disengage the loopers will make the operation a lot faster and more efficient. However, if you rarely need to work on your serger for more than 30 minutes, you probably won’t benefit much from the additional features.
For home uses that don’t usually handle lots of projects, Juki MO644D is sufficient. It is powerful and effective to get the job done. However, if you need the ability to swap to the two-thread stitches quickly or the ability to disengage the loopers for threading, you should choose Juki MO654DE. This model is especially useful for taking care of lots of projects quickly.
