I have recently picked up a B5100 tractor. I know a FEL was available on these tractors and have downloaded some pics off the net, but none really show what I need to see. I'm trying to figure out how the sub-frame was made and how it mounted. If someone can give me a link to a site that has a manual with this info, or post some pics of a comparable Kubota with some really good shots of the sub-frame, that would be great. Thanks.
