Protect your crop with conditioner options to fit your needs
Achieving the right conditioning action can significantly reduce dry down time. That means less time needed to cure, maintaining optimum feed values, and preventing leaf loss in legumes. Hay and forage producers have a wide variety of crops and conditions. That’s why John Deere mower-conditioners offer four different conditioners.
Conditioning reduces the time required for dry down
Multiple conditioner options match a wide variety of crop types
Faster dry down can increase nutrients retained in harvested crops
Suitable for traditional dry hay or haylage operations
Conditioner types include:
Impeller – ideal for light-stemmed grasses and alfalfa that respond well to scuffing of the stems
Urethane – a soft roll that provides excellent performance in legumes and grasses
V10 steel – increased crimping for faster dry down and improved wear life
Tri-Lobe™ conditioner – a premium, patented roll system that uses a chevron design to crimp and crush
Reduced maintenance and proven cutterbar reliability with 5-year coverage
John Deere's patented design cutterbar is made from individual, diagonal-cut modules, making serviceability easy. Each module can be removed for service individually, leaving the remaining cutterbar modules attached to the frame.
Nodular iron modules are highly resistant to impact damage
Large, heavy-duty idler gears reduce driveline speed and wear
Shear hub protection minimizes cost and decreases repair time in the field
Gauge shoes provide accurate control of cut height and protect cutterbar
Low-profile cutterbar allows the operator to cut at a flatter angle for improved cut quality and reduced wear on components
Common oil bath keeps internal components lubricated and reduce oil-level checkpoints
Because John Deere is confident in the reliability, every mower conditioner includes a 5-year warranty on cutterbar components. This gives you peace of mind knowing that if you do experience a warrantable failure, your machine is backed through your experienced, local John Deere dealer.
Each cutting disk is attached to a shear hub (driver) on the splined pinion gear. Power to the disk is interrupted when the driver shears to protect the internal components of the cutterbar. Damage is limited to exposed components and does not require disassembly of the cutting modules.
Reduces damage to the cutterbar and driveline components
Improved uptime with limited disassembly required
The gauge shoe setting determines the height of the crop stubble, but also prevents the majority of the cutterbar from being in constant contact with abrasive soils and rocks. The S250, S300, S350, C300, C350, and C400 have three height adjustments on the gauge shoe. The C450 and C500 come from the factory with six adjustments. Through service attachments, gauge shoe extensions are available to increase the number of adjustments if there is a need for higher stubble height.
