I had a friend of mine move to fla and leave me with an ht20 with a mower, blower, and tiller. Well being the procrastinator that I am I decided to wait until now to put the thrower on. I see that I am missing 2 arms that attach to the back of the blower mount and 2 springs that must be for counterbalance of the blower weight. I can make probably everything that I need I was just wondering if I could get some pics of how its mounted. The blower is a 48 inch 18148. Thanks for your time. Also have a JD 400 with a mower deck and tiller. Planning on building a FEL for my wife with the JD.
