John Deere 420D Draper

Cutterbar visibility

Center visibility

Left-side visibility

Right-side visibility

The cutterbar and frame designs give excellent visibility across the full range of tilt.

The cutterbar and belt can be easily seen from the cab even with the optional top-crop conveying auger installed.

The cutterbar can be tilted from the cab mechanically or hydraulically depending on the windrower option chosen.

This allows operators to optimize the cutterbar angle for varying crop and field conditions, thus extending the harvest day and providing the best possible cut height and crop flow.

C-shaped cutterbar profile

The unique C-shaped cutterbar allows for easy crop flow onto the draper while providing a superior draper-to-cutterbar seal. The seal between the top of the C-shaped cutterbar and the draper belt is important to limit the amount of material that gets under the belts. The open design at the bottom of the C-shaped cutterbar allows any material that does get past the seal to fall back out. This reduces the amount of material that gets inside the draper belts. This cutterbar shape promotes smooth crop flow across the cutterbar, minimizing hesitation and crop loss in shatter-prone crops.

400D integral slow-speed transport system (W155 shown)

The 430D, 435D, and 440D Draper models can be equipped with an integral, slow-speed transport system. One person can convert the draper from field to transport in minutes without the use of tools.

The W155 Self-Propelled Windrower is the only model approved to tow a 400D Draper Platform. Transport is also recommended behind a tractor with a seven-pin electrical lighting outlet.

Dual front-dolly wheel tires and two gauge-wheel tires carry the complete weight of the draper when in transport.

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

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

Dual gauge wheel option

400D Series Draper Platforms offer optional 38.1-cm (15-in.) dual gauge wheels with spring suspension. This, combined with the windrower float system, provides flotation and excellent ground following in all conditions.
 
The operator can fine adjust the float on the go from the cab, allowing high-speed harvesting and stable flotation with the assistance of the adjustable spring-loaded gauge wheels.
 
The gauge wheels are also available as part of the integrated slow-speed transport system option.

435D split-span reel with plastic fingers

Cam reel tooth action

Reel in full forward position

The 400D Draper Platform features a cam design reel that feeds well in all crop conditions.

The cam pickup reel features a 165-cm (65-in.) effective diameter and utilizes heavy-duty plastic or steel fingers and heavy tine tubes. The reel features a cam to control tooth position. The smooth cam action and heavy tine-tube design allows the reel to operate at higher speeds with a smoother, quieter operation. This gives better feeding with less wear on the reel drive components and, more importantly, less shatter of the crop harvested.

Hourglass-shaped reel

Reel endfingers

The reel is designed and assembled to have an hourglass shape. This allows the ends to be positioned closer to the cutterbar for positive feeding while keeping the fingers at the center of the reel span from coming into contact with the cutterbar. Feeding is most important at the ends. Other reel designs do not have the capability of such tight adjustment. The hourglass shape is designed with an adjustable bolt position on the reel tine tube brackets to the disks.

Optional end fingers improve feeding aggressiveness in difficult feeding and cutting conditions with down and tangled crop.

Adjustable cam positions

The cam position and reel position are adjustable, enabling the machine settings to be matched with the crop conditions for a trouble-free harvest. The finger release position is easily adjustable to one of four cam positions.

The reel is hydraulically positioned up, down, and fore-aft to allow perfect positioning for gentle yet positive feeding action.

Plastic fingers come standard from the factory on all platforms. Steel finger options are available through Parts and are recommended for heavy forage crop conditions due to their longer life. The plastic fingers are recommended for all crop conditions. The plastic fingers weigh less and work well in all crops. The plastic fingers are easier to replace individually without having to disassemble the other fingers on the reel tube section.

All 10.7-m (35-ft) split-reel platforms (North America and export) and the 12.2-m (40-ft) split-reel platforms (North America only) come standard with tine tube stiffener kits to handle heavy crop conditions and improve the life of the platform.

Plastic tine split reel with end feed fingers

The reel is available in a single span only from 4.6-m (15-ft), 6.1-m (20-ft), and 7.6-m (25-ft) sizes. Single-span or split-reel spans are available in 9.1-m (30-ft) to 10.7-m (35-ft) sizes. Split reel only is available in 12.2 m (40 ft) size. There are optional end feed fingers (three per end are available as field installed) for tough feeding conditions.

The single-span reel offers less weight and better center visibility. It is a good option for producers who harvest canola and small grains for oil and seed.
 
The split-reel span gives better feeding in adverse crop conditions such as heavy, wet, and down crop. The split span gives better control of the reel height on wider platforms for more consistent feeding.

Five-bat reel

Six-bat reel

Nine-bat reel

The reel is available in five-, six-, or nine-bat configurations. The nine-bat configuration provides more interaction for more positive and smooth crop flow in heavy down crop conditions. Additional bats can be field installed to convert from six bats to nine bats. Additional bat configurations are recommended for heavy crop conditions such as silage and grass seed crops.

Sales and service delivered

Sales, parts, and service support from a local John Deere dealer offers overnight parts delivery and a well-trained support staff.

Platform reverser controls on W155

An optional reverser is available for the W155 Self-Propelled Windrower only. It is easily activated from the operator's station to clear the platform of plugs that may occur.

On the 400D Draper Platforms, the reverser slowly reverses the knife drive and optional hay conditioner if equipped to clear plugs. The reverser is highly recommended when using the optional hay conditioner with the 400D Platform.

On the 100A Auger Platform, the reverser slowly reverses the conditioning rolls, auger, and reel. This makes a difficult job easier, so the operator can be more productive.

Operators can run the machines nearer to their maximum capacity and it will take less time to unplug, adding to the machine's productivity.

Reverser valve block

The reverser consists of a valve block and valves, shown in image above. It is the gold-colored valve block on the right side. It is shown plumbed for a 100A Auger Platform.
