Now that looks like a nice owners Manual. Most owns manuals is full of take it to your friendly dealer for repairs so he can get into your wallet :smile:
Don't know your physical disabilities but I have yet to see a riding mower of that style that the belt can be changed from the top. It might be a lot easier if you remove the deck first. Also if you can get one of the newer mower jacks that can lift the front of the mower high might help you. This jack would also be helpful to change, sharpen blades and clean under the mower deck. One service call would pay for the jack so it wouldn't be a waste buying one. Hope you the best on this :thumbsup:
