Get the part numbers from that drawing of the parts that you need and do a Google search on them. Different JD dealers give different discounts for different parts, so if you want to find them for the cheapest price you will need to search around. If you're ordering things on-line, don't forget to find out what the shipping costs are as some sites list prices that are way lower than others for the actual parts, but their shipping charges might be much higher and eat up the difference. Also, any dealer that has a location within your state is required to collect sales tax even if you place the order on the internet, while out-of-state dealers do not have to charge sales tax.
