Brother BB370 vs. Brother XR3140 Comparison

In this comparison, we are going to compare one of the most popular affordable sewing machines, the Brother BB370 and Brother XR3140. What made these two sewing machines stand out was that they were packed with features in an affordable range combined with excellent stitch quality.

What are the major differences between the two? Below I will describe the differences in the simplest terms possible.

Brother BB370 vs. Brother XR3140: Comparison in Features

Sewing Machine Types

The Brother BB370 is a mechanical sewing machine, while the Brother XR3140 is a computerized sewing machine. Since the machine types decide they differ a lot in features, I won’t make a suggestion.

You should choose carefully based on your sewing skills and goal.

Brother BB370 vs. Brother XR3140 : Built-in Stitches

The Brother BB370 has 37 stitches. The Brother XR3140 on the other hand comes with 140 built-in stitches. The apparent difference is in the buttonhole styles, where Brother BB370 comes with One 1-step buttonhole(s), Brother XR3140 sewing machine has only 8 one-step buttonhole(s).

Start/Stop Button

The Brother BB370 doesn’t come with a start/stop button, while the Brother XR3140 sewing machine does. One of the best ways of controlling some of your variables within free motion quilting is by using your start/stop button.

Speed Control Slider

The Brother XR3140 arrives with a speed control slider while the Brother BB370 sewing machine doesn’t. A speed control slide is a useful feature that allows you to set the maximum speed you are comfortable with.

Automatic Needle Threader

Many sewing machines sold today come with an automatic threader function. This is essentially a lever that will guide the thread through the eye of your sewing needle for you so that you don’t have to do it yourself. Many sewists prefer to thread their own needles, but if you have difficulty performing this task, then a machine with an automatic needle threader might be very useful for you. Fortunately, these two sewing machines both come with automatic needle threader, allowing you to thread the machine with ease.

Drop-in Bobbin

The advantage of easy drop-in, top load bobbins is that you can readily see how much thread is left on the bobbin through the window. You do not have to remove the bobbin case to insert a new bobbin, and you do not have to remove the accessory tray from the free arm to change bobbins. Both the Brother BB370 sewing machine and the Brother XR3140 sewing machine come with this user-friendly feature.

Free Arm

There is free arm on both the Brother BB370 and the Brother XR3140. The free arm is a very useful feature to all sewing machines as it makes sewing one layer of fabric without catching another. This is because all of the workings around the bobbin race, feed dogs, and needles are housed there.

The Verdict

Feature-wise, the Brother BB370 and the Brother XR3140 differ a lot. However, the common factor is the stitch quality. These two machines provide consistent stitches over a variety of fabrics. If you ask me to pick an affordable advanced sewing machine, I will pick any one of these two machines. Since they differ a lot in features, I won’t make a suggestion. The decision has to be made on your sewing skill and sewing level.

Q. Why adjust tension on sewing machine

A. Sewing machine tension adjustment is controlled by devices that separately control the needle thread and the bobbin thread, putting varying amounts of tension (or strength) on the threads they control to form a strong, balanced stitch.

Q. What are features to look for in a sewing machine?

A. The best features will depend on the type of sewing you plan to do. For a beginner, some features to look for include built-in stitch types, an automatic needle threader, a top drop-in bobbin, and a set of standard presser feet.

Q. Can i use serger thread in my sewing machine

A. Do not use serger thread in your sewing machine. These spools of thread are tempting to buy because they’re inexpensive, but they have a very rough texture on the thread. So if you put it in your regular sewing machine, it’s going to break and jam and you’ll be really frustrated.

Q. What type of maintenance do sewing machines need?

A. Today’s sewing machines usually require just a few basic steps to keep them in good working order. While the manual included with your machine will spell out the details, it’s important to regularly remove the throat plate and use a small, soft brush to remove thread, lint, and debris that might have become lodged inside the machine. Your machine may also require oiling to keep everything lubricated and running smoothly.

Q. Can i use 3 in 1 oil on my sewing machine

A. You shouldn’t use cooking oil or automotive oil in your machine, since doing so may clog the gears and damage any fabric used in the machine. Also, 3-in-1 oil is not suitable for sewing machines, according to Threads magazine.

Q. Can a regular sewing machine sew vinyl?

A. Yes, with the same modifications listed above for leather.
