Give Your Planter A Complete Check-Up

Consistent planter performance depends on proper adjustment and maintenance. Here are tips from planter experts at Kinze.

The folks at Kinze® Manufacturing, Inc. understand time is money during planting season as farmers rush to get their seed in the ground. Many Kinze employees also are farmers and understand the critical nature of proper planter maintenance to ensure planters are ready to place the seed into the ground when the planting window opens. 

Give Your Planter A Complete Check-Up

Do the basics first, recommends Phil Jennings, Kinze Manufacturing's service manager at the company's headquarters at Williamsburg, Iowa. "Consistent planter performance starts with a planter that is in good mechanical condition," he explains. "Make a close inspection of the soil engaging components on the row units. Badly worn parts must be replaced or planter efficiency will be impaired."

Checking disc opener blades is an important step. Farmers should check the wear on disc blades and replace 15-inch blades when they are worn to 14.5 inches in diameter. Inspect the disc blade contact too. "Optimal disc blade contact is 1 to 1.5 inches to form the seed trench," Jennings says.

There are a number of things to inspect on your planter, some not so obvious

Take a look at the inner scraper to be sure it protects the seed tube. "This prevents soil buildup between the opener blades," Jennings says. "Replace scrapers when they are worn to five-eighths inch or less."

When inspecting gauge wheels, check for light contact of the tire to the blade in the operating position, Jennings says. He also recommends looking over the arm and bushings. Different field conditions can affect the depth adjustment of the planter. "Be sure to check and adjust the depth when field conditions change," Jennings recommends.

Do not forget how important it is to assess closing wheel performance. The closing wheels must be centered over the seed trench. "Apply only enough down pressure to maintain good seed to soil contact," Jennings states. Closing wheels may be offset slightly for better residue flow, he adds. If the closing wheel plugs with crop residue, the seed trench won't close properly. An optional closing wheel shield might be needed to help prevent stalks from lodging in the closing wheel arm.

Hitch adjustment is a factor influencing consistent seed depth and spacing

"Hitch adjustment is another important factor of consistent seed depth, spacing and seed to soil contact," Jennings says. "Adjust the hitch height so the tongue runs parallel to the ground when the planter is in planting position," he states. The parallel arms of the row unit should be approximately level when the toolbar is 20 to 22 inches above the planting surface. On the planter's parallel arms, check the bolts, bushings, down pressure springs and the drive chains to be sure all the parts are performing optimally.

Do not forget other planter attachments that contribute to uniform seed placement. Inspecting no-till planter parts also is critical to optimizing planter efficiency. No-till coulters should be set at a depth slightly above the disc opener blades. Residue wheels are intended to move obstacles in the path of the row unit. This reduces hair pinning of the crop residue and creates smoother row unit operation. Residue wheels should be adjusted to just skim the planting surface and may not turn 100% of the time. If the tines of the wheel are building up with moist soil, they are set too deep, Jennings says.

Confirm what you "think" is happening; check what's actually going on in field

Always confirm what you "think" is happening with a full field check. It is not enough to just dig a few seeds up behind the planter. Jennings strongly recommends a full 1/1000th acre field check when any settings or adjustments change. For 30-inch rows, that is 17 feet 5 inches row length. Tie up a set of closing wheels and drive ahead at planting speed. "Take the time to prove it to yourself that the job is getting done right," he says. "The extra 15 minutes is an inexpensive insurance policy. Dirt is the real test." Farmers then can visibly see all of the critical factors for success, including consistent seed depth, seed spacing, and seed to soil contact.
