I just purchased a 3 point LW-3 Backhoe attachment for my NH TC-30. Just getting started with putting it together.First my tractor does have a front end loader and I had rear hydraulics added to the rear with 2 connectors.The Lw-6 by the distributer said the Lw-6 would tie into my rear TC -30 hydraulics.The Lw-6 has a oil resevoir installed on the back hoe 1 line coming from the backhoe control valve into the side of the oil resevoir and on the other side a line coming off the side to attach to the tractor.I have so many questions it's hard were to start.Everything that I have researched if you are hooking into the tractor hydrualics that you should by pass the oil resevoir for the backhoe that would only be used if you would use a pto pump is this correct? Most pictures of the Lw-6 backhoes show 2 hoses to hook to the tractor I have only 1 coming from the oil resevoir? The back hoe has metric fittings on the hoses can I get metric fittings 1 end and standrad to fit my tractor on the other end. Will the back hoe work better using the tractor hydraulics or getting a pto pump? Thanks!!!!!!!
