  • Running vacuum seeder with older Ford

    I have a '68 Ford 8000 that I am planning to use to run a JD MaxEmerge 2 system. What I can't find is whether the older Ford remote valves will handle continuous flow reqs of a hyd vacuum motor. The Ford output is 12 GPM. Can't find the JD flow req in the manual. Besides flow, are there other issues to consider? Thanks!

    Depends on size of planter, but ballpark guesstimates for a 12-row planter: 7 to 10 gpm to raise/lower, 8 to 12 gpm to run 2 vacuum motors, 2 to 5 gpm to raise/lower markers, and 1 to 3 gpm to operate hydraulically-driven variable rate drive motors, if the planter is driven that way. So, if all those are running at one time (when raising the planter on a headland) it could require between 25 to 30 gpm of flow at minimum of 2200 psi.
