Hey guys, first post. Thanks ahead for all the info. I've been reading alot from the forums on rear hydraulics, power beyond and top and tilt kits. I'm really interested in adding a top and tilt kit to my Kubota L3700SU. I have basic understanding of hydraulics and thanks to the forums, have figured out the power beyond concept. I am in the process of gathering parts for a top and tilt kit for my tractor and was looking through all the spool valve at the Surplus Center. Any recomendations on which 2 Spool valve would be best for my particular tractor? Thanks again.
