i know what you mean, usually i just get 4 screwdrivers some glue and a hacksaw but i just had a look at the 7930 i have it would probably be a bit difficult to add front linkage, because it has such a thin front end theres nothing to wedge it in to so i dont know \ and usually if i want weights for my front linkage i use a siku front linkage, nick the weights off any random britains tractor using a hacksaw and then buy a siku linkage adapter set, glue one of the adapters onto the weight and then it will slot onto the front linkage, i will get a pic of my jd weights i did soon
