2025 John Deere FA 20

Fast, efficient cutting for higher harvesting speeds

The 600 Series HydraFlex™ Platforms were designed to match the high capacity of the S-series Combines and are equipped with a range of performance boosting features.

Features May Include:

• HydraFlex™ float system improves operator control

The HydraFlex system hydraulically controls the float of the cutterbar by a simple turn of a knob in the cab. This provides exceptional cutterbar flexibility throughout the entire working pressure range. Higher ground speeds can be accomplished with HydraFlex, compared to the conventional float systems.

Feature benefit:

• The mechanical linkage is replaced by float arms with hydraulic cylinders at every channel. These cylinders provide the cutterbar with the ability to float over uneven ground conditions with improved operator control. Reference the operator’s manual for settings recommendations.

  NOTE: The hydraulic cylinders will be on every other channel on 630F and 635F models in model year 2022.

• The platform HydraFlex system with an accumulator maintains a constant ground pressure over changing ground conditions. Manual mode is for locking out the cutterbar in the rigid mode.

• Epicyclic knife drive increases drive capacity

The heavy-duty epicyclic knife drive gearbox provides an enhanced knife-drive system that increases drive capacity with less vibration and improved reliability.

FEATURE BENEFIT:

• Provides high level of reliability and durability
• Minimizes vibration
• Fast, efficient cutting action for higher harvesting speeds

• Enhanced single-point latching system is fast and easy

John Deere’s single-point header latching system provides combine operators a fast and easy method for connecting all front-end equipment. One easy motion of the lever connects the electrical and hydraulic circuits along with header retaining pins.

Feature benefit:

• Reduces the time required to change over headers
• No tools required to remove headers for transport or storage

Functionality:

The enhanced single-point latching system, includes a valve assembly mounted to all platform and corn head back sheets. These assemblies include an orifice valve unique to the header type and a pressure override valve. Together, these valves ensure the performance and reliability of header hydraulic functions.
