Here is another company from Spain that converts them!!! I bought my hydraulic kit for my liebhrr loader from them, but I haven't got it installed yet!!! Hydraulic is expensive, but will out work any electric setup 3 to 1 in my experience!!! I haven't built either, but from talking to people and seeing them work, that's what I have seen!!! Hope this helps!!!
