Hi Adam,
I would check with Charlie- he may have it. If not, you can look at other sites and try and find it. If you can't find it online, you may have to make it.
My turn for a question: A few years back, I asked about a fix for my mule drive that kept sliding out of the quick attach. To fix this, I mounted the mule drive where I wanted it, and drilled a hole in the frame and put a bolt in to hold it. This works well for the deck. Recently, I needed my blade to do some grading work, and the same thing happened with it. Dad tied a piece of wire around the PTO engagement lever to hold the quick attach lever up. Well, I looked on the parts diagram and I am missing those little springs that go in on the sides. With them being NLA, do any of you guys have a fix, or should I try and find the springs???? If I have to find the springs, I won't be able to get them this year, but if there is a work around I would sure like to know. Thanks!
