Understanding and adjusting the feed dog height on your Brother sewing machine can significantly improve the quality of your stitching and broaden the range of fabrics you can successfully sew. The feed dogs, those little teeth-like protrusions beneath the needle plate, are crucial for moving fabric evenly under the needle. This comprehensive guide will walk you through the process, explain the reasons for adjustment, and cover troubleshooting tips to ensure your sewing experience is smooth and efficient.
Why Adjust Feed Dog Height?
The primary function of the feed dogs is to grip the fabric and advance it at a consistent rate, creating uniform stitches. However, not all fabrics are created equal. Some are thick and plush, while others are thin and delicate. The default feed dog height that comes standard on your machine may not be optimal for every type of material.
A feed dog set too high can aggressively grip and pull at delicate fabrics like silk or chiffon, leading to puckering, stretching, or even damage. Conversely, feed dogs set too low may struggle to grip thicker fabrics like denim or upholstery material, resulting in skipped stitches, uneven feeding, and frustration.
Adjusting the feed dog height allows you to customize your machine’s performance for specific fabrics, ensuring even and consistent feeding, clean stitches, and professional-looking results. It gives you greater control over your sewing projects and allows you to tackle a wider variety of materials with confidence. It’s not just about getting the job done; it’s about achieving the best possible outcome for every project.
Identifying the Need for Adjustment
How do you know when it’s time to adjust your feed dog height? Here are a few telltale signs:
- Fabric Puckering or Stretching: This is a common indicator that the feed dogs are too aggressive for the fabric. The fabric may bunch up ahead of the needle, creating unsightly puckers, or it might stretch out of shape, particularly with knit fabrics.
- Skipped Stitches: If the feed dogs aren’t adequately gripping the fabric, the needle may miss its mark, resulting in skipped stitches. This can be especially noticeable when sewing multiple layers of fabric.
- Uneven Feeding: The fabric may feed unevenly, causing the stitch length to vary or the fabric to veer off course. This can be due to the feed dogs struggling to maintain consistent contact with the fabric.
- Difficulty Sewing Thick Fabrics: If you’re struggling to feed thick fabrics through your machine, even with a walking foot, the feed dogs may not be high enough to effectively grip and advance the material.
- Damage to Delicate Fabrics: Observe the fabric closely as it feeds. If you see any signs of the feed dogs snagging or tearing the fabric, they are likely too high.
- Unusual Noises: Sometimes, incorrect feed dog height can cause unusual noises from the machine, signaling that something isn’t quite right with the feeding mechanism.
If you experience any of these issues, it’s worth investigating whether adjusting the feed dog height can resolve the problem.
Locating the Feed Dog Adjustment Mechanism
The location of the feed dog adjustment mechanism varies depending on the Brother sewing machine model. Some machines have an external adjustment lever or dial, while others require accessing an internal adjustment screw.
- Consult Your User Manual: This is the most important step. Your user manual will provide specific instructions and diagrams for locating and adjusting the feed dog height on your particular machine model. Do not attempt to adjust anything without first consulting the manual. The manual is your guide to proper and safe adjustment.
- External Adjustment: Some Brother machines have a lever or dial, typically located near the feed dogs or on the side of the machine, that allows you to raise or lower the feed dogs. This is the easiest type of adjustment.
- Internal Adjustment: Other models require you to remove the needle plate and access an adjustment screw. This screw is usually located near the feed dog assembly. Again, refer to your user manual for the exact location. Always unplug your machine before removing the needle plate or accessing internal components.
- Safety First: Before you start, turn off and unplug your sewing machine to prevent accidental activation and potential injury.
Adjusting Feed Dog Height: A Step-by-Step Guide

Make the Adjustment:
- External Adjustment: If your machine has a lever or dial, simply move it to the desired position. Typically, there will be markings indicating higher or lower feed dog settings.
- Internal Adjustment: If your machine has an adjustment screw, use a small screwdriver to carefully turn the screw. Turning the screw clockwise usually lowers the feed dogs, while turning it counterclockwise raises them. Make small adjustments and test the machine frequently.
- Test the Adjustment: After making an adjustment, reassemble the needle plate (if removed), replace the presser foot, and thread the machine. Test sew on a scrap of the fabric you plan to use for your project. Observe the stitch quality, fabric feeding, and any signs of puckering or skipped stitches.
- Fine-Tune: If the initial adjustment doesn’t completely resolve the issue, make further small adjustments and retest. Continue this process until you achieve the desired results. Small adjustments are key. Avoid making drastic changes at once.
Troubleshooting Common Issues After Adjustment
Even after careful adjustment, you may encounter some challenges. Here’s how to troubleshoot common problems:
- Feed Dogs Still Too Aggressive: If the fabric is still puckering or stretching even after lowering the feed dogs, try using a thinner needle, reducing the presser foot pressure, or using a stabilizer. A walking foot can also help distribute the feeding pressure.
- Feed Dogs Not Gripping Enough: If the feed dogs are not gripping the fabric adequately even after raising them, check for lint or debris buildup around the feed dogs and clean them thoroughly. Make sure you’re using the correct type of needle for the fabric. A textured foot can help improve grip.
- Machine Jamming or Making Unusual Noises: If the machine jams or makes unusual noises after adjustment, double-check that all components are properly reassembled and that the feed dogs are moving freely. Ensure proper lubrication of the machine as well.
- Stitch Length Inconsistency: This could point to an issue with the stitch length setting itself, or persistent issues with the feed dogs’ contact on the fabric. Experiment with different stitch length settings and ensure the fabric is feeding smoothly. If problems persist, consult a qualified sewing machine technician.
Tips for Successful Feed Dog Adjustment
Here are some additional tips to ensure a successful feed dog adjustment:
- Keep a Sewing Journal: Document your adjustments and the fabrics they work best with. This will save you time and frustration in the future.

Why is adjusting the feed dog height important for my Brother sewing machine?
Adjusting the feed dog height is crucial for achieving consistent and accurate fabric feeding. When the feed dogs are correctly positioned, they grip the fabric effectively, pulling it through the machine at a uniform rate. This prevents skipped stitches, puckering, and uneven seams, especially when working with different fabric weights and textures. A properly adjusted feed dog height ensures your sewing machine operates smoothly and produces professional-looking results.
Furthermore, the wrong feed dog height can damage delicate fabrics or struggle with thicker materials. Too high, and the feed dogs might snag and tear thinner fabrics. Too low, and they may not be able to grip heavier fabrics, leading to inconsistent feeding and potentially damaging the needle. Fine-tuning the feed dog height allows you to adapt your machine to the specific needs of each sewing project, extending the life of your fabrics and your sewing machine.
How do I know if my Brother sewing machine’s feed dogs need adjustment?
Several signs indicate that your Brother sewing machine’s feed dogs may require adjustment. The most common symptom is inconsistent fabric feeding, where the fabric either moves too slowly, too quickly, or unevenly. You might also notice skipped stitches, where the needle fails to create a stitch in certain areas, or puckering along the seam, caused by the fabric being pulled unevenly by the feed dogs.
Another indicator is a struggle to sew different fabric weights. If your machine handles lightweight fabrics perfectly but struggles with denim or multiple layers of cotton, the feed dogs might be set too low. Conversely, if it damages delicate fabrics, the feed dogs might be too high. Regular observation of your machine’s performance with various fabrics will help you determine if feed dog adjustment is necessary.
Where is the feed dog height adjustment located on my Brother sewing machine?
The location of the feed dog height adjustment mechanism on your Brother sewing machine varies depending on the model. Some models have a small screw or dial located near the feed dogs themselves, often accessible from the needle plate area. This adjustment allows you to raise or lower the feed dogs directly. Refer to your machine’s manual for the exact location of this adjustment.
Other Brother sewing machine models may not have a manual feed dog height adjustment. In these cases, the feed dog height is factory-set.

If your machine has a screw-type adjustment, you will likely need a small screwdriver that fits the screw head. A flathead screwdriver is often the most common tool for this purpose. Ensure the screwdriver is appropriately sized to prevent stripping the screw head.
In some cases, a specialized wrench or adjustment tool might be required. Again, consult your machine’s manual to determine the exact tool needed. A small brush or compressed air can be helpful for cleaning any lint or debris around the feed dogs before and after adjustment. Good lighting is also essential to clearly see the feed dogs and the adjustment mechanism.
How high should the feed dogs be above the needle plate on my Brother sewing machine?
The ideal height of the feed dogs above the needle plate varies depending on the type of fabric you are sewing. As a general guideline, the feed dogs should protrude slightly above the needle plate, enough to firmly grip the fabric. For most standard fabrics, a height of approximately 0.5mm to 1.0mm above the needle plate is a good starting point.
When working with thicker fabrics like denim or multiple layers of quilting cotton, you might need to raise the feed dogs slightly higher to ensure proper feeding. Conversely, when sewing delicate fabrics such as silk or chiffon, lowering the feed dogs slightly can help prevent snagging and damage. Experimenting with different heights and testing on scrap fabric is the best way to determine the optimal setting for each project.
Can I completely disable the feed dogs on my Brother sewing machine?
Yes, many Brother sewing machines offer the option to completely disable the feed dogs. This feature is often used for free-motion quilting, darning, or embroidery, where you need to control the fabric movement manually. Disabling the feed dogs prevents them from pulling the fabric, allowing you to move it freely under the needle.
The method for disabling the feed dogs varies by model. Some machines have a lever or switch that lowers and locks the feed dogs beneath the needle plate. Others require a special darning plate to be installed, which covers the feed dogs. Consult your machine’s manual for instructions on how to disengage the feed dogs on your specific Brother sewing machine model.
What should I do if I cannot adjust the feed dog height on my Brother sewing machine?
If you are unable to adjust the feed dog height on your Brother sewing machine, first double-check your machine’s manual to ensure you are following the correct procedure.
