Hello, I've just upgraded to a JD3050 (for me it's an upgrade) but it needs a few jobs sorting out on it before I can start using it. Please bear with me - I'm pretty new to farming and know next to nothing about tractors less than 35 years old. Obviously a photo would really help here, and I'll go and take one to post here when I get a chance, but: There is no check chain on the right hand side. In the parts catalogues they have check chains which look like check chains always look. However, on the tractor the left hand one is not a chain and has a gaitor type thing on it; whereas the broken right hand one looks more like a gas strut. One end of this has sheared off the bracket. Does this make sense to anyone? What is that strut called? Why has it got this arrangement rather than the chains the parts book seems to think it ought to have? It's a 1991 model. This is it from the front (but I'm talking about the back linkage): Thanks, NP.
