My foot dog will not pull the fabric as I sew? I'm having to pull it manually myself .. Anyone know how to fix this problem?

Could be the presser foot is not applying enough pressure to the feed dogs. Check your owner manual for instructions on increasing the presser foot pressure. Could also be that the feed dog height needs to be adjusted or their teeth are worn (do not run the machine without fabric between the presser foot and feed dogs).

Sewing machines have feed dogs to pull the fabric through the machine. They are usually a pair of metal teeth that are situated in the needleplate and press against the presser foot. They grip the fabric and pull the fabric under the presser foot as the needle stitches.

You can find the drop feed dog instructions in the owner's manual:

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.

Check to be sure you have not inadvertently dropped the feed dogs on your machine. Dropped feed dogs are used for 'darning' or 'free motion quilting.' Below is info from Troubleshooting Manual:

Fabric does not feed through the machine
The feed dogs are lowered. Use the feed dog position switch to raise the feed dogs. 81
The stitches are too close together. Lengthen the stitch length. 42
The wrong presser foot was used. Attach the correct presser foot. 179
The needle is bent or blunt. Replace the needle with a new one. 34
The thread is tangled. Use scissors, etc., to cut the tangled thread and remove it from the race, etc.

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.

the presser foot or what ever foot your sewing with does not feed the
fabric,, the feed dogs in the needle plate are what moves the fabric
to be sewed, the feet only hold the fabric against feed dog so the
machine can use the needle to sew the fabric.
if the fabric is not moving then the feed dogs have to be checked
can you see the feed dogs in the needle plate area are the up or
down?
do you have a manual for the machine?
a manual help to know where the feed dog lever is, I'm sending
you a link for a manual for the machine, so you can look for the feed
dog lever, if the feed dogs are up then there is something wrong
with the feed dogs & they need to be checked.
but if the feed dogs are down then look in the manual & see where
the feed dog lever is & put it in the up position & see if that brings
the feed dogs up to the sewing position, if the feed dogs do not
come up then the feed dogs need to be checked.

have you checked the presser foot to see if the presser foot is holding
the fabric against the feed dogs so they can move the fabric thru to
be sewn by the needle?

what is the name of the machine?
do you want a manual?
the feed dogs are what move the fabric thru the machine, the presser foot only hold the fabric against the feed dogs so the feed dogs can move the fabric
the feed dogs in the needle plate area should be up

White sewing machine model 510, feed dog problem; fabric is not moving; I must firmly pull fabric through.

The feed dog is moving; fabric is not.

The fabric is not feeding properly; the fabric goes back and forth. However, the fabric does not continue to move away from me.

The feed dog is positioned up and is not smooth, it feels rough when I touch it with my fingers.

Because I had not used this sewing machine for a couple of years, before sewing, I cleaned the inside with the wire brush that came with the machine.

In an attempt to trouble shoot the problem, I applied varying pressure foot levels and stitch lengths.

Does anyone have any suggestions as to what may be the problem?

adjust your feed dog hight. manual shows u how
