I have a Kubota M5140 with 3 rear remote hydraulic connections installed by dealer. I want to purchase a front end rotary cutter which the hydraulics on the M5140 will handle (11 gpm). Two of the remotes are not used, and I used one pair for my grapple. I intended to use one of the other sets for the hydraulic cutter (trailblazer TB-flex cutter or similar). Manual says Do Not connect motor return to remotes. Does anyone know if there is a plug I can remove, add a quick connect, and allow the return line to go directly back to the sump?
