JD Picking Unit System

Premium Aftermarket Replacement Parts

The picking unit system plays an important role in any John Deere cotton harvesting machine, as it separates cotton from the spindles as they rotate, and while these spindles are spinning away, they’re extracting all the cotton lint from the bowl of the plant as the plants are funneled through the row-unit. While the picking unit bars keep those spindles separated so that they can maintain their rapid action, the picker ribs or grid bars clear away all the dried leaves, twigs, and other debris that gets picked up along with the plants.

If this material were not separated from the plant, it would all remain mixed with the cotton, and it would call for an entirely separate process to remove it down the line. That would undoubtedly be a much more expensive process than eliminating it from the rapidly turning spindles, and it would be difficult to do as good a job in a secondary process.

With the picker ribs doing a good job of clearing away all this unwanted material, it prevents having the moistening systems or the doffers from clogging up with that same undesirable debris. If the harvesting parts become clogged up with cockleburs, leaves, and twigs, it could drastically impact their ability to pick properly and quickly. That of course, would add time and expense to the whole harvesting process, and it would decrease the profitability of your harvest crop.

Ordering Parts for the Picker Unit System

To ensure you order the right parts for your John Deere machinery when you’re in communication with Certi-Pik USA, it’s best to use our part number for the item. This generally begins with a number, or you can provide us with the OEM part number, which more often begins with a letter of the alphabet. Some items have this part number etched right into their surface, but if you don’t know it, you should be able to find it in the documentation for your harvesting machine, whether it is your picker’s owner’s manual or our catalog.

Once you know that, you’ll be able to track down any cam roller, left or right cam arm, square key, upper or lower seals, O-ring seals, sleeves, plugs, bars, bushings, shims, bolts, washers, dirt scrapers, spindles or any other individual component which goes into the picker bar and spindle assembly.
