This is a wet kit we recently designed built and installed on the model 1890 John Deere tool bar.  The grain tank was already on but we added a liquid/starter tank and plumbing that goes to all the openers through Raven flow controls and custom manifolds.  Another thing that was installed was variable rate product control through the Raven Omniseed system.  Our fab shop also adapted this auger to the back for filling with seed.  A swiveling arm and heavy duty lock down latch when seeding makes this a well-designed and lasting system.  Tight timelines made this one a rush but we got it done.
