MegaWide™ pickup with MegaTough™ pickup teeth offers super capacity
451M MegaWide pickup
A MegaWide pickup is base equipment on 451M, 461M, 551M, and 561M Round Balers.
Hydraulic pickup is in base configuration on 451R, 461M, 461R, 561M, 561R.
Hydraulic pickup is an option on 451E (dealer installed), 451M (factory installed), 551M (factory installed)
MegaWide pickups make baling easier, especially in wide or windblown windrows, and increases productivity; more hay volume means more bales per hour.
- Flare-to-flare width of 1.8 m (5.9 ft) on balers with a 1.2 m (4-ft) wide bale chamber
- MegaWide pickup makes it easier to produce better-shaped bales and improves crop pickup in wide, windblown, or scattered windrows
- Mega teeth, located at the ends of the pickup, pull crop around the flares when baling wide or windblown windrows
- MegaTough pickup teeth provide greater strength and durability
- Exclusive square design handles high-impact loads without yielding
- Sturdy toothbar design
- Self-adjusting roller baffle
- Spiral rotor-feed system improves feeding in all crop conditions
- Chain driven for positive feeding
- Cut-out clutch protected
- Semi-pneumatic gauge wheels
MegaTough pickup teeth
Mega and MegaTough pickup teeth are base equipment:
- Mega teeth, at the ends of the pickup, are heavy-duty for long life and improved crop retrieval
- MegaTough pickup teeth are designed to withstand the harshest baling conditions and provide long service life
Toothbars on 1.5-m (5-ft) baler
The 1.2-m (4-ft) balers use a full-length, reinforced toothbar design.
The 1.5-m (5-ft) balers use a heavy, C-channel construction. The pickup toothbars are divided into two half-sections that mount to a center spider for increased strength and even crop feeding.
Roller baffle
Available only on the MegaWide Plus pickup, the patented roller baffle is self-adjusting and produces smoother crop flow across the pickup. The roller also improves crop pickup in small windrows and prevents roll ahead of crop.
When combined with the MegaWide Plus pickup, this feeding system allows increased ground speed with less chance of plugging for increased productivity in all field conditions.
- Self-adjusting
- Smooths crop for even flow across pickup
- Allows for faster ground speed with less chance of plugging
- Increases operator productivity
Spiral rotor
Auger and rotor feed system
The MegaWide Plus pickup uses a rotor-feeding assembly, which mounts behind the pickup for smooth and even crop flow into the bale chamber.
- Augers and rotor teeth are driven on the same shaft, eliminating the need for additional drives.
- The rotor is fixed to the baler frame, allowing positive and even feeding into the bale chamber.
- Large-diameter converging augers have high crop-flow capacity, and auger scrolls help to force crop into the chamber.
- Spiral design enhances feeding in uneven windrows and reduces loading on the rotor.
Rotor stripper
Rotor strippers allow crop to be lifted from the rotor teeth into the chamber without cutting or wrapping the crop.
Cut-out clutch protection and feeder-drive chain
The MegaWide Plus pickups and spiral rotor are chain-driven for positive bale starts with cutout clutch protection. The pickup is being driven off the drive roll and bypasses the starter roll. This will allow for reduced wear and breakage of the starter roll chain.
Semi-pneumatic gauge wheel
Semi-pneumatic gauge wheels provide smooth ground gauging over uneven terrain and protection to the pickup.
- Stiffer rubber sidewalls
- No air pressure to maintain, which mean no flat tires
- Adjustable to meet pickup tooth-to-stubble height requirements
The pickup float springs are positioned for excellent flotation.
- Adjustable to meet varying field conditions
- Float springs only support the pickup reel
- Rotor assembly is fixed to the baler frame, eliminating additional weight on the pickup system
Adjustable crank handle
The adjusting crank positions the pickup to the desired operating height to match crop or field conditions.
An optional hydraulic pickup lift cylinder is available as an attachment.
- Makes raising for transport or clearing obstructions easy
- Crank handle serves as a down stop
- Adapts to regular, MegaTooth and MegaWide Plus pickups
- Hydraulic pickup lift comes standard on premium machines
Heavy Duty Package

- Two year or 12,000 bale Warranty
- Cam-Cut Out Clutch
- Heavy-Duty Chain
- Pickup - Heavier Spider Gear, Cam Arm Bearings, Cam Shafts, and Bearings in Spider
- Larger Diameter Shaft and Bearings on #11 and #9 rolls
- Grease Bank
Silage configuration
Staggered roller-auger kit
A silage-configuration baler allows the producer to put up silage hay. A silage configuration machine does not offer a precutter. There are three major components to a silage configuration baler: a staggered roller-auger kit (1), a starter roll-scraper knife, and a screen (2). The powered auger sits above the staggered roll on the baler to help keep wet hay from traveling up the belts and reduce buildup on the roll. The screen is bolted on the front of the baler as a safety feature. The knife/scraper is mounted in front of the starter roll to help prevent wrapping of wet crop on the starter roll.
The silage kit is offered as a bundle for field installation if the baler is not ordered as a silage-configuration machine from the factory. Attachment BE32442 is for 1.22-m (4-ft) wide machines and BE32443 is for1.52-m (5-ft) wide machines.
Also offered is a high-moisture kit. This kit does not include the same components that are on the silage-configuration balers. It offers the starter roll-scraper knife but does not include the staggered roll-auger kit. Attachment BE23828 is for 1.22-m (4-ft) machines and BE23829 is for 1.52-m (5-ft) machines.
Starter roll knife and screen
Base equipment on: 451M Silage, 551M Silage, 461M Silage, 561M Silage, 451R Precutter, 461M, 461R Precutter, 561M and 561R Precutter
Auxiliary take-up rolls
Auxiliary take-up rolls prevent belt crossover and flipping in wet conditions. This roll is base equipment on all silage and precutter configuration balers.
Bale scale and moisture sensor
Bale scale and moisture sensor
Bale scale and moisture sensor
Bale scale and moisture sensor
Integrated-sensor measurements for weight and moisture provide bale characteristics (moisture/weight). This technology enables producers to document bale moisture and weight and take data into Operations Center for post-harvest analysis. This allows better management decisions around water and nutrients, plus document that information to get higher prices for their bales, as well as possibly reduce their input costs.
Net lift assist and net lighting

G5e external speaker
G5e External Speaker Device
G5e External Speaker Device
The G5e External Speaker is an optional attachment for G5e displays only.
- Provides increased volume levels for all G5e display notifications
- Assist baling operations in situations with high in-cab noise or for operators with hearing impairments
- Installed externally on harness for easy access
- Omits sound separate from G5e display speaker to increase volume up to 16 percent
- Manually adjust volume by turning front dial left or right
The external speaker device provides increased volume levels for all G5e display notifications. It will omit a sound separate from the G5e display to assist baling operations in situations with high in-cab noise or for operators with hearing impairments. It is installed externally on the harness and can have volume levels changed by manually turning the front dial left or right. Adding the external speaker increases G5e notification volume by 16 percent. The external speaker is optional and is available as an attachment.
Adjustable hitch to match wide array of tractor drawbar heights
Side view of adjustable hitch
Front view of adjustable hitch
The 1 Series Round Balers came standard with an adjustable hitch and this feature will continue to be in base with the 1 Series Round Balers. This feature allows the hitch height to be adjusted to optimize crop-feeding performance. Due to the wide array of tractor tire sizes and drawbar heights, hitch adjustment may be necessary to get the proper feed opening of the baler. The adjustable hitch eliminates the need for the 51-mm (2-in.) thick tractor drawbar kit (AE57344) because it has a wider opening.
Benefits of the adjustable hitch:
- Ability to match baler to numerous tire sizes
- Allows for drawbar height to fall within 330 mm to 559 mm (13 in. to 22 in.) from the top of the drawbar to the ground
- Eliminates narrow feed opening on the baler which can cause plugging
- Allows pickup head to follow terrain without missing crop
All eight bolts must be used when adjusting the hitch. There are four different positions as shown below:
Position 1 (top) (factory setting) - regular pickups
Position 2
Position 3 (factory setting) - MegaWide
Position 4 (bottom)
Also standard on all 1 Series Round Balers, except the 451E, is the drawbar shield. This helps to eliminate hay from getting caught on the hitch of the baler. The drawbar shield is designed to allow the operator to remove or attach the flap without having to unhook the baler from the tractor.

Vertical forming chamber maintains uniform bale density
Bale-starting diagram
As the hay enters the forming chamber from the pickup, belts immediately turn the hay to form a tight, dense core.
Incoming hay then feeds between the bale and the lower gate roll. Hay is tightly compressed into smooth, dense layers as it enters the bale.
Chaffing is greatly reduced to prevent loss and retain hay quality in the bale.
Full-sized bale in bale chamber
The idler arm rises with bale growth, forcing oil from the hydraulic cylinder through a pressure-relief valve to maintain uniform bale density throughout the bale-forming process.
Exclusive DiamondTough™ belts with plate-type splices
Staggered belts
John Deere's 178-mm (7-in.) wide diamond-tread design ensures fast bale starts and grips the bale to prevent slippage and reduce chaffing. The treads are self-cleaning to reduce carryover. The belts are staggered to reduce the loss of fine material and are closely spaced to contain the hay for fast, easy starts.
The belts enclose 91 percent of the bale width to reduce loss of fine material and retain hay quality.
The staggered belt roll design enables any loose hay under or behind the belts to be returned to the pickup and into the baler. This design helps to prevent buildup at the front of the baler, which could cause hay loss and belt or splice damage.
DiamondTough triple-weave belts
Every baler in the 1 Series Family uses DiamondTough belts. Belts are constructed using a patented triple-weave process of nylon and polyester materials.
They have the strength to handle heavy shock loads and help maintain consistent belt length.
The DiamondTough belts are more puncture and tear resistant than other belts on the market and provide improved belt life and reliability.
Plate-type fasteners
Plate-type splices
All of the 1 Series Balers use the plate-type fasteners.
This closed-loop design uses a plate fastener with pre-assembled rivets that lock the fasteners into the belt, providing a powerful vice-type grip on the belt.
- The plates and rivets are manufactured from high-tensile stainless steel.
- Strong belt splices mean less maintenance and more productivity.
- The loop area is cold forged, making it extremely wear resistant in the coupling area, resulting in a very long cycle life.
- The spring steel pin is notched and locks into the splice connection without having to bend the pin or use external retainers.
Additional features available on the 1 Series Round Balers
All M- and R-specification 1 Series Balers have the same stamped, steel door design.
Factory-installed grease bank
Grease bank
Standard on premium round balers is a factory-installed grease bank. This allows the operator to only have to grease eight zerks (four on each side of the baler) for grease zerks that were hard to reach on previous models. The operator will still have to grease the driveline and some other components on the baler.
NOTE: The grease bank will also be found on all 1 Series precutter configuration balers.
ISOBUS system
Connection of ISO monitor wiring harness to the tractor
Controller on baler
The ISOBUS system offered on the premium round balers allows the operator to use the latest technology when baling. They can utilize their GreenStar™ 2600, GreenStar 2630, GreenStar 1800, or certain R-Series CommandCenter displays as their baling monitor and can switch between tractors without having to take the display with them. All information for the baler is stored on the controller.
Warranty
A two-year or 12,000-bale warranty comes standard on 460R Premium and 560R Premium Round Balers only. Please see full product warranty for more details.
