I am glad to hear that all will finally be coming together. Let us know how the Backhoe works with the 2305. Also, glad to hear that there are no more issues with the radiator.
I have been enjoying the 2305. I use the box blade the most, but I definitely believe the top link that comes with the 2305 is too long. I am going to get a cheap one and cut 2 inches out of it as is explained by Davkir in a post in JD Owning/Operating section named "2305 Box Blade Problem".
The standard top link will not allow you to pitch the blade forward enough. So far this is the only trouble I have had with the tractor.
I hope it all smooths out after the kit is installed.
