TOO MUCH SPACE. An extreme example of a 4½-inch-wide depth-gauge wheel that isnâ??t adjusted close to the disc blade. The tire lip is worn down so much thereâ??s a ½- to ¾-inch gap between it and the opening disc, which leaves the disc vulnerable to soil buildup and poor soil penetration.

Narrow, High-Tech Gauge Wheels Tackle Plugging, Emergence Issues

New materials and designs for depth-gauge wheels can help growers improve seed-depth consistency and emergence in tough no-till conditions, and possibly increase yields.

When it comes to no-till planters and drills, row cleaners and closing wheels often get the most attention from growers, giving rise to seemingly endless tweaking and innovation devoted to the attachments.

Gauge wheels, experts seem to agree, aren’t doted over nearly as much — even though they perform an essential function of establishing consistent seed-depth placement that is key to uniform emergence.

“I honestly can’t believe it sometimes when I go out and look at some planters and see the condition the gauge wheels are in, and that’s so important,” says Andy Thompson, an area manager for Yetter Mfg. Co.

But as no-till practices continue to grow, and demands placed on planters continue to increase, gauge-wheel dimension designs are undergoing some important changes.

There’s an emerging movement among no-tillers toward adopting narrower gauge wheels of 2½ to 3 inches instead of the 4- or 4½-inch wheels that come standard on most major planters.

Gauge wheel designs themselves are also evolving, with newer, more durable materials being used, as well as open, spoked wheels that allow mud and residue to flow through the row unit without plugging up the wheels and opening discs.

Innovation Necessary

The role of gauge wheels with planters is only going to increase in importance as growers push planting speeds faster or implement narrow-row cropping systems, says planter and drill expert Phil Needham, co-owner of Needham Ag Technologies.

Currently, only a handful of planter manufacturers offer narrow gauge wheels as an option out of the factory…
