Feed dog synchronizes with needle bar feeding that creates a nice even looking stitch row.
Changing the needle is easy and convenient; and so is for changing a feed dog and presser foot (standard specification: ?" =6.4MM)
Upper shaft bushing and shaft bushing of take-up lever run by rolling shaft. No noise and handy with operation.
Use of a rolling shaft on the upper shaft lowers the level of friction that prevents the machine parts from being time-worn. Thus, the machine can be maintained in a good condition.
The design of fully automatic lubrication enforces an adequate amount of oil that results in smooth and quiet operation.
TC-8720 is designed by double the size of a large bobbin which reduces the frequency of changing the bobbin thread; and which also rises up sewing efficiency.
