We have been using these type of chain for a few years now ,they definately do a better job than any of the prickle harrows in two ways.They mulch and chop stubble rather than fluff like the others tend to do.Secondly they do not wrap like the prickle chains do which means you can do tall weeds as well as vines on the ground that used to make the others big rolling sausages.

Pics of disk chain I will attach has well over 100,000 acres on it and wear is very minimal,most operation would not wear one out in a life-time.Chain is anchor-chain with bisalloy discs welded to it,very simple.Newer ones have option of curved discs which do work soil a little deeper and take a little more to pull.

A 60 ft chain can easily be pulled by a 200hp plus mfwd,an 8420 plays with a 64ft.
