| Attaching 1770 Deere planter with variable rate drive transmissions to CIH STX 275 4WD tractor. Hydraulic's for variable rate drive is attached to tractors power beyond ports with a 3rd line for load sense. When all is connected, the tractor cranks over very slowly and is putting an excessive hydraulic load on the tractor, so much so that the starter does not have enough power to crank the engine over. If the hoses from the variable drive are uncoupled from the tractor, the engine cranks and starts fine.
Is anyone familar with this tractors power beyond feature to know exactly how to connect the load sense line to the inlet side of the power beyond or the return side of power beyond? Have 2 different CNH dealers trying to solve problem and they have not had much experience with this tractor using the power beyond.
