Have tried agriline but they dont do cultivator bits, just been in mole valley and have had the last 1 they've got, but they arent going to have any more, have started stocking 1/2" as a replacement, not much good!
Will keep eye out but think may be easier to buy some replacment mats for points from sale as new 1's seem to be rare as hens teeth unless theres some in stock on a shelf somewhere. Thanks for the help.
