Hi to every one. I have a cat grader h series I bought it used and the rock guard behind the mouldboard is missing. Have someone an idea what to do to protect the hoses behind the mouldboard?I ask for the original but is really expensive
I see 3 optional guards listed on a brochure but not sure if any of them are what you require. Can you post a pic. of the hoses you want to protect? I'd guess a steel cover could be made but would need to see where the hoses are. Looking at standard pics. I don't see any exposed hoses on the back of the moldboard. Could be because of the guard you're talking about though. The other thought is maybe steel lines were replaced with hoses. A pic. would be a great help.
Look this mr have the guard for the cylinder of the sideshift
The company below manufactures aftermarket guards. If you give them a part number and a scan of the parts book page, they may be able to fabricate one for you.

Most guards are relatively simple to manufacture.
From what I can see, looking at a brochure, it looks like the guards are basically a piece of plate bent to enclose the back of blade including the hoses. The plate goes from below the slide shift cylinder up most of the height of the moldboard. If the machine isn't used for much backblading or working in a lot of rocks and the operator is paying attention I think you could still use the machine for most applications until you had the guards made. Shouldn't be too hard to make for a fab. shop with a press brake. Need to make sure they don't interfere with side shifting the blade to either side. I couldn't tell if the guards are attached to the curved arms coming from the drawbar.
Pic was taken late on a smokey afternoon, but this is what they look like. They just drop over the long bolt on the top of the mouldboard and the brackets fasten them to the big round beam on the bottom. They don’t do a lot to protect hoses. We do a lot of bush work and find that nearly all hose damage is from sticks etc. coming over the top, so we don’t bother with the guards anymore.
