Single Roll vs. Dual Roll Adapter

Struggling to keep up in the field? Want to pick faster and finish more acres each day? We can help!

At Kooima Ag, we take the time to solve real-world harvesting challenges. This success story shows just how much performance you can gain by dialing in your setup. Follow along as Nolan shares how one customer significantly increased their earlage harvesting speed using Kooima Ag parts.

The Original Setup: Single-Roll Adapter

This customer was operating a Claas® 970-498 series with compression rollers, a Case IH® 3412 corn head, and the Kooima Ag K00494 single-roll adapter. In previous seasons, they had trouble moving efficiently with the compression rollers. The harvester struggled to feed corn effectively, limiting speeds to 1.5-2 miles per hour (mph).

The K502STOP, A Smart Upgrade with Big Impact

To help improve feedroll flow, we installed the Kooima Ag K502STOP. This part raises the upper feed rolls a couple of inches, allowing more space for corn to move through the chopper cleanly. With this upgrade, customers' speeds increased to 4-4.2 mph. That's more than double the pace they were used to, with smoother feeding and a noticeable improvement in productivity.

Taking It Further by Upgrading to the Dual Roll Adapter

Next, we upgraded to the Kooima Ag K00498 dual roll adapter. We kept everything the same: the Claas 970-498 series machine, Case IH 3412 corn head, and the same field, but the results improved once again. 

• Increased speed to 4.6 mph
• No bubbling
• Improved performance in various conditions

The field the customer was working in was green corn. Green corn tends to pick a little easier, and a dual roll adapter will do better in the drier corn in the middle of the afternoon, when it's dusty and slippery. You will gain about a half-mile-an-hour to one mile an hour difference. 

To maximize the system, we made a few more improvements to the K0048 dual roll adapter. By adding 1 ¼" shims to the front feed roll and reinstalling the front springs for better feeding consistency, the customer reached speeds of 5.5-6 mph. 

Let's Get You Moving Faster

The customer was extremely satisfied with the results. What started as a slow and frustrating harvest setup was transformed into a faster and more efficient system. With the right combination of adapters and upgrades, they were able to cover more acres with less effort.
