Liquid delivery feature of Valion seed tube guards is U.S. Had the spring been oriented in another direction (e.g., pushing straight down), the problem wouldn’t be nearly so bad.Ĭontent of this page is copyright 2005-2022 Exapta Solutions, Inc. ![]() Because the spring is nearly parallel to the swing-arm, it has almost no down-stroke-i.e., the spring is in the optimum position (applying the correct amount of downforce) for only about 0.25-inch of its range. While it’s true that a swing-arm isn’t as good as a parallel link, the worst issue with the 50/60/90 opener is actually the way that down-pressure is applied to it. Some will say that the swing-arm design, where the opener pivots from a single point (rather than a parallel link) is the worst downfall. Perhaps the worst downfall of these drills is the way that down-force is applied to the opener-the rockshaft twists to compress a big coil spring on each opener. Yet there are plenty of shortcomings with these drills, and Exapta has been busy addressing those. ![]() ![]() Many of you know that I view these drills as being superior to many others on the market because of: 1) depth gauging alongside the blade, 2) an in-furrow seed-lock wheel.
