When I originally was quoted a price, I think it was $1450. (about 6 weeks ago) I decided to order a QA bucket ( I didn't order one on my loader) and also a toothbar. So I think she knocked off some more because of that. I suppose your loader came with the Kubota bucket. Maybe you can sell it rather than modify it. Markham's bucket was much cheaper than any other I priced. Used ones are easy to find also. As far as the binders, I am using straps. There is a rigger's supply near me and they can make anything for a reasonable price. I also bought some from Northern. I kind of new to this, as I have only had my trailer since November. I have transported my tractor only twice, about 20 miles each time. So far, it has worked out well. Never having used chains, I don't have any comparisons. I am careful to watch out for sharp corners that could cause wear. Finding somewhere to hook to the tractor is not easy.
Are you getting a WR Long electric over hydraulic valve? It really works well. Also when you install this, buy some abrasion resistant sleeve to encase the long hydraulic lines from the valve to the grapple quick connects. Those lines really move a lot and rub against the tractor. Catching these line with a stick would be easy, so the sleeve offers some protection. The grapple came with flush face skid steer type quick connects and my valve kit came with the Ag type. So consider that and maybe order either the valve or the grapple with whatever type you choose, rather than having to switch one end out at the installation. It seems that since you are going to a lot of expense to make the FEL skid steer compatible, the hydraulics should also be skid steer type, but I may not ever use any other implement, and most skid steer implements require more hydraulic flow than we have anyway. I switched out the grapple to the Ag type, as they were the only kind my dealer had available. So now I have a $50 pair of skid steer connects that I probably will never use. Save some money and order the right kind to begin with. Hope this helps. Keep us informed on the progress. I love spending somebody else's money! Seriously, I know you will be pleased with how it works.
