One or more techniques and/or systems are disclosed for automatically adjusting conditioning rollers of a windrower implement, such as those used to condition hay and other windrowed crops. Adjustments can be made on the fly to rollers used to condition the crop based on several factors such as the condition of the crop, the density, speed, header conditions, and more. Sensors can be used to detect the crop's and others' conditions, and automatic adjustments can be made, such as the distance between conditioning rollers, and/or the pressure applied by the rollers, to meet a desired crop condition for the windrows.
