question for you deere techs on a 7200 vacume planter.
both the pressure and return lines from the hyd blower motor are connected to the tractors SCV. Do I remember that the return line should dump to sump so the blower can free wheel when you kill the flow with the SCV?
This planter keeps shearing the drive key.... blower is ok and motor shaft is ok... no damage seen on both and key fits tightly in shaft and blower.
I think the sudden stop when the SCV is kicked to netural is causing the problem but its been afew yrs since I worked in a green shop.
I seen to recall adding a hyd fitting and dumping return oil to sump bypassing the SCV.
Am I a confused old man or just dreaming?
