From the President's Cab: blessed to have each other
Posted On: November 19, 2022

By Raymond Liska

Shaking, rattling, grinding, knocking, are all too familiar to farm equipment operators. Torn belts, loose bolts, and failed bearings are just a few things that could be wrong and must be dealt with immediately. 

Having a good sense for something going wrong is as important as being able to turn the wheel when the harvest is on the line. Operators use their skills and experiences to manage their machines persistently day in and day out. 

Online equipment auction benefits WCO; Nov. 22-Dec. 6
Posted On: November 19, 2022

WCO is proud to announce an online auction, Nov. 22–Dec. 6th, coordinated by Hansen Auction Group. The auction includes machinery typical for custom operators, but virtually all items will be considered.

As an association, WCO is looking for creative ways to maintain a strong financial position. Like all of our members, WCO’s investments have taken a hit and membership is slowly recovering from the pandemic. In addition, we have ideas for several new programs that could become a reality with additional funds.
