I'm interested in possibly updating our drill to an 1870. It would be a 56' with a new variable rate1910 tbt pulling an nh3 wagon behind the drill. Our current tractor has standard hydraulics, so I'm thinking around 40ish gpm.....and has no problems operating a hoe drill with variable rate cart. Once the 1870 accumulators are charged is there any other flow requirements to maintain proper operation of the openers or packers? Are any of you operating this drill and variable rate 1910 with standard hydraulics? If so, would you please share your experiences (good and bad)? I hear about all the flow requirements on the other independent opener drills so I'm left wondering if standard flow hydraulics would be sufficient to operate the 1870 properly. Thanks, and I appreciate any comments you may have.
