    The cutterbar design provides excellent visibility across the full range of tilt:

    • Cutterbar and belt can be easily seen from cab even with optional top-crop conveying auger installed
    • Cutterbar can be tilted from cab mechanically or hydraulically depending on windrower option chosen
    • Change cutterbar angle with varying crop and field conditions for best cut height and crop flow
  • Hydraulic deck shift gives larger windrows for more efficient harvesting

    John Deere 425D, 430D, 435D, and 440D Drapers can windrow out of the center, right, or left ends of the draper with effortless change using the hydraulic deck-shift option.

    Hydraulic deck shift option:

    • Larger windrows to match combine or self-propelled forage harvester
    • Match narrower-width drapers with higher-capacity harvesting
    • Place higher-density windrows in front of harvesters when yields are low
    • Discharge two windrows side by side for uniform combine or forage harvester feeding
    • Move chain stop to change center belt opening quickly and easily for different crop types and density (see operator’s manual for more information)
    • Discharge crop to the outside of the headland to prevent running over the windrow while cutting the rest of the field
    • Platform stays balanced with automatic fine-float adjustment when using deck shift
    • Optional double draper drive bundle is recommended when using deck shift and harvesting silage or wet, heavy crops
      • NOTE: The double draper drive option is not compatible with the 425D Platform.

    Slow-speed transport system:

    • 400D Drapers are towable only with W155 and W170 Self-Propelled Windrowers
    • Transport is recommended behind a tractor with seven-pin electrical lighting outlet
    • 430D, 435D and 440D Drapers only
    • Convert draper from field to transport in minutes with one person and without tools
    • Dual front dolly wheel tires and two, gauge wheel tires carry weight of transport


    It is a simple four-step process to switch from field to transport:

    1. Move right gauge wheels from field to transport
    2. Move left gauge wheels from field to transport
    3. Attach the tongue.
    4. Detach from the windrower.
