Quicker Dry Down

Getting your hay crop dried down fast is important, especially if you have weather events looming. The John Deere S250, S300, S350, C300, C350 and C400 Mower-Conditioners give you the ability for wider windrows, thanks to the forming vanes. These wider windrows help the crop dry down faster, preserving the quality of the hay and giving you more time to bale before Mother Nature strikes.
