The swathboard of a windrower can be remotely adjusted from the tractor seat and on-the-go using an electro-mechanical actuator or other rem otely operated actuating device. When the swathboard is adjusted to its fully rais ed position, the stream of crop materials issuing from the conditioner rolls bypasses the swathboard and engages the forming shields to be converged into a windrow having a widt h determined by the outlet formed between the rear ends of the shields. At the other extreme, when the swathboard is fully lowered, the stream impinges against t he swathboard and drops to the ground in a wide swath without ever engaging the forming shields. In any one of a number of intermediate positions, the swathboard ca n be used by the operator to deflect the stream to engage wider or narrower portions o f the forming shields, thus controlling the width of the windrow.
