More Hectares Per Hour

Get more done in a day with the new John Deere C500 Mower Conditioner. The 5m (16ft. 4in.) cutting width of the new C500 lets you cover up to 10% more hectares per hour*. *compared to previous models

Increased Tractor Compatibility

Now you can mow with a wider range of tractors and handle hills easier, due to the lighter weight of the John Deere C400 Mower-Conditioner. In addition to the flexibility to use lower horsepower tractors, you get wider conditioning rolls, Quick Change Knives and continued great maneuverability and durability with swivel hitch options.

Save Time with Quick Change Knives

Cut your time changing knives in half* with the Quick Change Knives, available on the redesigned John Deere Zero Series Mower-Conditioners, letting you spend less time servicing your mower and more time cutting hay. Changing a knife in the field is easier than ever with Quick Change Knives, helping you maintain the best cut quality. *compared to standard bolted knives of previous models

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.
