Feed dogs don't pull the fabric through evenly, can I adjust them higher?

Are they in the raised position? Are they dirty--debris stuck between the teeth? Is the stitch length set to a higher number that will produce a longer stitch? Are they actually moving at all? When the presser foot is lowered, is it actually resting on the feed dogs? If you are sewing light weight fabric, you may need to adjust the presser foot pressure adjustment.

Make sure the feed dogs are not in the dropped position (for darning).

If it is very light-weight fabric, most machines will have a presser foot pressure adjustment that will increase the presser foot's pressure on the feed dogs, thus pulling the fabric through better.

Make sure the feed dogs are clean--no debris stuck between the teeth, under the feed dogs, or around the bobbin case. If it is an older machine that has been used a lot, the feed dogs could be worn down and need replacement or adjustment. (Do not run the machine with the presser foot directly on the feed dogs. This will cause excessive wear to the feed dogs and the presser foot.)

Check that the feed dogs have not been dropped for darning or free motion quilting. If the feed dogs do not rise above the needleplate, they will not pull the fabric through the machine.

Feed dogs do wear (which is why one should always sew with fabric against the feed dogs--never on bare metal).

Something else that happens is that gunk builds up between the teeth of the feed dogs so that they no longer have the grip they need to move the fabric.

Another thing to check is the presser foot "pressure." A lot of sewing machines have a pressure adjustment that increases or decreases the amount of pressure the presser foot applies to the fabric and feed dogs. (Consult your owners manual.) he pressure can be adjusted according to the type of fabric being sewn.

Adjusting the presser foot pressure on your sewing machine

sewing patternreview com

...

Make sure the stitch length is set long enough to actually advance the fabric. If set too short, the fabric movement will be very minimal. Also check that the presser foot pressure adjustment is set for the type of fabric you are sewing. The adjustment can be made for light- or heavy-weight fabric. If the presser foot pressure is too tight or too loose, it will have difficulty pulling the fabric.

***Your feed dog under the pressure foot seems to be pulling on one side a little harder which indicates wear. It is likely to solve the problem by replacing the feed dog.
***Before you do this try to lower the pressure on the pressure foot. If the material you are sewing is thick it will have an effect on the pull of the feed dogs. The material you are sewing that you sent appears to be jeans material. It looks like it is thick and somewhat slippery.

When you sew the machine must be set at the correct settings. If your machine won't straight stitch, turn it off at the power point and then turn it back on. Most machines reset to the default straight stitch setting. Secondly when you sew the presser foot must be down. This engages the "feed dogs" or the triangular looking "teeth" below the presser foot. As you sew, the feed dogs grab the two layers of fabric pulling them through, the thread above (spool) and the thread below (bobbin) meet to form the stitch. Finally, maybe fiddling around with dials and settings you may have dropped, or disengaged the feed dogs. Check with your manual on how to re-engage the feed dogs. Hope this helps and happy sewing. Remember, when all else fails..... read the manual.

I hope this is of some help different Fabrics need more or less downward pressure for the pick up dogs to move it forward, if you have tried this and that's not the problem then your feed dogs are worn but you can shim them up by removing the and cutting a piece of thick polythene of even thin paper or card be carful that yo don't make the drive dogs to high as this will then put holes in thin fabrics it,s trial and error to get it right.

Good luck

A walking foot is a foot with feed dogs, or a similar fabric moving mechanism. This is useful when there are many layers of fabric or slick fabric. Then the top layer of fabric can be made to travel at the same rate as the lowest layer (the feed dogs) or an slightly different rate. Then the fabric layers will stay even for the entire length of the seam.

A walking foot sewing machine has this feature built in. Thus you don't need to adjust extra hardware to keep your fabric aligned. (On some, specific feet are needed to use the feature. However, it is easier to adjust than the separate walking foot that I have for my older Singer sewing machine.)

I hope this helps.

First, remove the needle plate and using a small screwdriver, clean the packed lint from in between the teeth.This will allow the teeth to go up.
