Necchi 4575 feed dogs won’t work does not push material through
If you raise the presser foot, set the stitch length to a 3 or higher, then slowly press the foot control, can you see the feed dogs rise, move backward, then drop and come forward again? If they are not moving, the feed dogs have seized. If they are moving but do not rise above the needle plate, then you have them disengaged.
If they are seized, resist the temptation to run the machine anymore until you can get it serviced. It could damage the motor causing more repair cost.
If they are disengaged (dropped), then you need to find the control lever or dial that engages them.
I cannot lower the presser foot on my necchi 681c sewing machine
Open the light cover
put some sewing machine oil on the long round
thingee, just above the black square
let this set for awhile
then use a chop stick or pencil/pen and push down [gently!!] on the square while pushing the lifter down
if this doesn't help, put a drop or 2 more of oil and let it set awhile longer
or use WD-40 to break it loose and then clean the long round thingee and put sewing machine oil on it
