I know this topic has been "beat to death" in the past postings but I have a problem adding a rear remote to a Kubota L235. The tractor has an FEL and a Gannon box scrapper on the rear. The hydraulic block under the seat has an in and out connection, both of which are used by the FEL. The FEL has an old style valve (made by victor, which is now bankrupt) which appears not to have a power beyond port so I can not hook it up as several articles mentioned. My question is how do I tap into the existing hydraulic system. Any help would be appreciated.
