I have an 8n backhoe with a flathead 6. This is my first tractor and I know very little about it. The loader has a hydraulic leak coming from inside the frame rail of the loader. My question is, is there a hose in the frame rail or does it have a built in reservoir? It looks to me that the hydraulic connections are welded in place right before the line coming from the control arms. The loader is from Davis products in Wichita KS. I believe it is close to the same age as this tractor. I can't seem to find any info about it. The attached picture is the tag on the loader. And the second pic is the tractor. I have loads of questions about this tractor, so any help will be greatly appreciated
