One thing that happens when you visit farm shows is that you find out not only what's brand new, but what companies have done to expand their line-up and offering of products. That was the case this year for those visiting the National Farm Machinery Show in Louisville.

The Yetter hydraulic air-adjust system offers another way you can control various features on the planter pneumatically with Yetter's air adjust system. The hydraulic pneumatic system is new from Yetter for this year. Yetter also still offers the electric compressor system introduced earlier.

New option for Yetter customers: The new hydraulic-powered compressor on the left is smaller than the original electric unit offered by Yetter for air-adjust systems on planters. However, the recovery time is faster for the hydraulic unit.

Get faster recharge time with the new hydraulic compressor option, spokespersons say. The choice may come down to which type of system works best with the tractor you use to pull the planter.

You can plumb directly into tractor remotes or hook into the hydraulic system at the planter level. If your tractor is maxed out on electric controls, this new hydraulic option may be appealing. In other cases if the tractor is already maxed out on hydraulic power, you still have the electric option.

Several Yetter products work with the pneumatic system, including row cleaners that can be controlled via air adjust from the cab, and downforce systems that apply pressure on planting units.

The new hydraulic unit contains a 12-gallon tank. Since it's smaller than the electric unit, you have more flexibility in where you place it. The decision could also come down to how you can plumb the hydraulics to operate the compressor. Electric units can lose some voltage if positioned a good distance back from the tractor on the planter.

Reviews
Here are comments from Farm Progress editors who have investigated new products at farm shows for a long time. The participants in this review based on information provided by the company are Tom J. Bechman, the author and editor of Indiana prairie Farmer, Lon Tonneson, Dakota Farmer and Mindy Ward, Missouri Ruralist.

Bechman: Controlling downforce on planter units and also being able to adjust row cleaners on the go are options people seem to like. More emphasis has been placed on the ability to control downforce on planter units lately. Many see it as crucial to getting uniform emergence, which is critical if you're after top yields. This new offering from Yetter gives them a line-up so you can go either with an electric or hydraulic unit, whichever fits your situation best.

Tonneson: This is another good option for being able to adjust row cleaner position, downforce on planter units and other components on-the-go. With corn a large part of the yield depends on precision planting, being able to change settings quickly to match conditions promises to increase yields.

Ward:  Well, if your tractor cab is on electronic device overload, Yetter has a solution for at least one system that might be electronic. The hydraulic air-adjust system offers you the option to control planter features with air. The system allows for row cleaners and downforce systems to be adjusted form the cab. This system has the advantage of quick on-the-go connections and a 25-seocnd recovery time.
