I do not know what you would call them in the US, but I have a device called a Sylvester that was used down coal mines in the UK and operates with a lever pulling a chain along a bar a one inch notch at a time. Very slow, but very certain. And nobody is at risk after attaching the pulling chain to the tractor. You do still need the original chain tightened every time you reach the end of the bar.
OMD,
That sounds like we call a "come along".
